What wildlife can you see on Roatan?

Mostly, it is underwater. Roatan sits at the southern end of the Mesoamerican Reef, and a mask and snorkel from the beach will put you among parrotfish, angelfish, rays and, often, turtles. Divers add eagle rays, seahorses, octopus at night and, on a specialist baited dive, Caribbean reef sharks. On land the island's own animals are smaller and rarer: an iguana and a coral snake found almost nowhere else, a native agouti, and an endangered parrot. The sloths and monkeys visitors photograph are not native to the island.

This is the guide to all of it, what is actually native, what you can realistically expect to see, and how to see it without being part of the problem.

What is the reef around Roatan?

The southern end of the Mesoamerican Reef, which runs for about 1,000 kilometers along the coasts of Mexico, Belize, Guatemala and Honduras. WWF describes it as the largest reef system in the Americas and the second largest in the world after the Great Barrier Reef. The phrase you will see everywhere, "second largest barrier reef", is looser than that: strictly, the barrier-reef title is usually given to the Belize section, though even WWF uses the phrase loosely at times.

Roatan's own reef is mostly fringing reef, starting close to shore, which is why you can swim to it from places like West Bay. Along parts of the coast it behaves more like a barrier, with a lagoon behind a reef crest, and a 2017 study in the journal Facies described the island as one of the rare Caribbean examples of an oceanic barrier reef system. Both are true in different places. Off the north side the reef drops away into deep water, which is what gives Roatan its walls.

Across the whole Mesoamerican Reef, WWF counts more than 65 species of stony coral and more than 500 species of fish.

What will you see snorkeling or diving?

The everyday cast is the reef fish: parrotfish, angelfish, surgeonfish, grunts, snappers and bright little damselfish guarding their patch of coral. On almost any snorkel or dive you will see those. Turtles and rays are frequent extras. Seahorses, octopus and nurse sharks take luck or a night dive, and Caribbean reef sharks take the specialist shark dive. The table below is our summary of what dive shops and published accounts report, not a survey, so treat it as a guide to the odds rather than a promise.

For snorkeling straight from the shore, West Bay and West End are the easy starting points: the reef begins a short swim out, and turtles, rays and big schools of reef fish are regular sights there.

Animal	How often reported	Notes
Hawksbill and green turtles	Common	West End dive shops logged more than a thousand turtle sightings in one summer in 2014, according to a ProTECTOR research report. Hawksbills are Critically Endangered; green turtles were moved to Least Concern globally in 2025
Spotted eagle rays	Fairly common	Among the likeliest large sightings on dives
Southern stingrays	Fairly common	On sand patches
Seahorses	Occasional	Divers look for them at sites like Mary's Place
Octopus	Common at night	Sometimes in water shallow enough to stand in
Nurse sharks	Occasional	The shark you are most likely to meet on an ordinary dive
Caribbean reef sharks	Occasional	Less common than nurse sharks on ordinary dives, and seen on most baited shark dives off the south side
Groupers	Common on wrecks and walls	Black grouper on the deeper walls and channels, and big groupers around the El Aguila wreck
Green moray eels	Common	Residents on the wrecks, especially El Aguila, and used to divers
Barracuda	Common	Often hanging in the blue off the walls and channels
Wild dolphins	Occasional	Seen from boats from time to time, especially off the north shore
Whale sharks	Rare	Seen off both Roatan and Utila; Utila is where the long-running research and the dedicated trips are
Hammerheads	Rare	Great and scalloped hammerheads have been recorded at a few Roatan sites by the shark-research group ilili, but nobody can plan around one

What lives on the wrecks and the deep walls?

Bigger fish, mostly. Roatan's two big freighter wrecks, El Aguila and the Odyssey, both sit at around 110 feet, deeper than the 60-foot limit of a basic Open Water course, so check what your dive shop requires. El Aguila, sunk in 1997 and broken into pieces by Hurricane Mitch the following year, is known for its resident green moray eels, which are well used to divers, and for big groupers and snappers around the hull. The Odyssey's superstructure is covered in azure vase and red rope sponges. The Prince Albert, off CoCo View, is a shallower wreck at around 65 feet.

On the deeper walls and channels, such as Peter's Place and Spooky Channel, black grouper and barracuda are regular sights, with horse-eye jacks patrolling the walls at Mary's Place. Caribbean reef sharks turn up on deeper dives from time to time, though the baited dive is still the reliable way to see them.

And for the truly deep, Stanley Submarines has taken passengers down from West End in a small private submersible since 1998, to as deep as 2,000 feet. Passengers report six-gill sharks and other rare deep-water sharks, dumbo octopus, coffinfish, sea lilies and bioluminescent animals glowing in the dark: a side of Roatan's wildlife that almost nobody else ever sees.

Can you swim with dolphins on Roatan?

Yes, at Anthony's Key Resort in Sandy Bay, where the Roatan Institute for Marine Sciences keeps a resident group of bottlenose dolphins at Bailey's Key. Encounters run from a 30-minute introduction to swims, snorkels and a trainer-for-a-day program. The cruise-port dolphin encounters we looked at all run there too.

It is worth knowing where the dolphins came from. According to a 2023 history in Paya magazine, the founding animals were caught in the wild off the Honduran coast near Trujillo between 1989 and 1990, with further captures in 1998, 2002 and 2003. At the time of that article the group numbered 17, all but two born at the facility. Welfare organizations such as Whale and Dolphin Conservation oppose keeping dolphins in any captivity, sea pens included, and that applies here as anywhere. Whether to book is your decision; we would rather you made it knowing the history. Wild dolphins are also seen around the island from time to time, which is the other way to meet one.

Can you dive with sharks on Roatan?

Yes. A specialist operator has run a baited Caribbean reef shark dive off the south side for well over two decades, and a second baited site, Marco's Place, is run by another dive center. Divers kneel on the sand at around 70 feet while a small amount of fish draws in the sharks, often somewhere between six and twenty, though numbers vary and no dive is guaranteed. Dive shops that sell it, such as Sun Divers, set their own requirements: some take Open Water divers, while others ask for Advanced Open Water or a minimum number of logged dives because of the depth and the currents. You book through a dive shop rather than directly. It is a controlled, briefed dive, quite different from meeting a shark on an ordinary reef dive.

Outside that dive, sharks are an occasional bonus rather than a feature, most often a nurse shark resting under a ledge. None of this is a reason to worry about swimming here: nurse sharks and Caribbean reef sharks are not considered dangerous to people, the species behind most serious bites around the world are not part of everyday diving on Roatan, and the only Roatan entry we could find in public shark-incident records dates back to a castaway in the 1720s. Honduras made all its waters a shark sanctuary in 2011, banning shark fishing across some 240,000 square kilometers of sea. A 2016 decree and its regulation later allowed limited use of sharks caught by accident in small-scale fishing, so the protection is strong but not absolute.

Where are the whale sharks?

Around both islands, but Utila, the next island west, is where the research and the dedicated whale shark trips are. Researchers there describe sightings in every month, with the most around March and April and a lot of variation from year to year; some guides add a second, smaller window later in the year. In early 2026, divers on Utila were reporting fewer sightings than in past years. Whale sharks also pass Roatan, and a 2025 citizen-science count by ilili logged more reports off Roatan than Utila, though that reflects where people were looking as much as where the sharks were. Nobody should promise you one.

What land animals are native to Roatan?

Fewer than you might expect, and a surprising number of them are found nowhere else on Earth. Islands do this: cut off from the mainland, small populations drift into species of their own. Most of Roatan's are reptiles, most are small, and nearly all are threatened.

Found only on Roatan

Roatan spiny-tailed iguana (Ctenosaura oedirhina), the island's "black iguana". The one you are most likely to meet, and the one locals usually mean when they talk about black iguanas: black to dark gray with cream bands that whiten with age, a rounded snout and a ringed, spiny tail. It lives only on Roatan, Barbareta and a few small cays, in dry forest, mangrove and scrub, and is Endangered, with the IUCN action plan putting the mature population below 4,500. Hunting, dogs, roads and interbreeding with introduced iguanas are the threats. Resorts and ecoparks are the likeliest places to see one, but not every iguana at an animal park is this species.
Roatan coral snake (Micrurus ruatanus). Black and red rings, with more black rings than its mainland relatives, and the island's only venomous snake. Critically Endangered and rarely seen; admire it from a distance if you ever do.
Roatan vine snake (Oxybelis wilsoni). A very slender snake that lives entirely in the trees and shrubs, named after the herpetologist Larry David Wilson. Endangered.
Roatan long-tailed snake (Enulius roatanensis). A small, secretive snake with an unusually long tail, living in leaf litter and burrows; first described from near Mud Hole Bay. Endangered, and almost never seen.
Roatan anole (Anolis roatanensis). A small anole lizard described in 2001, listed as Endangered, and hard to tell from its commoner cousins in the field.
Roatan least gecko (Sphaerodactylus leonardovaldesi). One of the smallest lizards on the island, with pale hip stripes and dark flecks, hiding in leaf litter and under palm fronds on Roatan, Barbareta and Isla Morat. Named after the Honduran biologist Leonardo Valdés Orellana.
Roatan freshwater crab (Potamocarcinus roatensis). A freshwater crab described in 2003 and listed as Vulnerable because its range is so small.

Found only in the Bay Islands

Yellow-naped parrot, Bay Islands subspecies (Amazona auropalliata caribaea). Paler and more olive than mainland birds, feeding on Caribbean pine cones on Roatan, Barbareta and Guanaja. The species is Critically Endangered, and only a few dozen birds roost on Roatan itself.
Bay Island least gecko (Sphaerodactylus rosaurae), named after the yacht of the expedition that collected it in the 1930s, and the Honduran leaf-toed gecko (Phyllodactylus palmeus), first described from Roatan. Both are tiny, nocturnal and Least Concern.

Other native animals

Roatan agouti. A rabbit-sized rodent, orange-brown with a white chin, often seen at dawn and dusk in scrub and resort gardens. It was long treated as an endemic species and is still listed by the IUCN as Endangered, but in 2026 the Mammal Diversity Database reclassified it as a distinctive island population of the Central American agouti.
Monkey la la. The local name for the brown basilisk (Basiliscus vittatus), the lizard famous for running across water on its hind legs, which is why it is also called the Jesus Christ lizard. It is common around streams, ponds and gardens, and it has also given its name to one of the island's best-known cocktails.
Green iguanas, native and common, and bats: a 2021 study of Utila's bats put the total for the Bay Islands at fifteen species.

The sloths and the monkeys are not on that list. Roatan has no native monkeys or sloths: the ones visitors photograph were brought from the mainland, many through the illegal wildlife trade. At Gumbalimba Park, white-faced capuchins wander freely around the grounds, but we found no record of a wild troop living independently anywhere else on the island. A January 2025 notice from Honduras's forestry and wildlife authority, the ICF, banned holding sloths, monkeys and other named animals for photographs.

How healthy is the reef?

It has had a hard few years, and we still think it is worth every dive. Here is the evidence on both sides, kept separate, because local damage and regional trends are different things.

Between 2023 and 2025 the Caribbean went through the worst marine heatwaves on record, part of what NOAA calls the fourth global coral bleaching event, and a 2026 study in Frontiers in Marine Science reported a 44 percent fall in live coral cover across three monitored sites at Cordelia Banks, just off Roatan's southwest coast, a reef that had held 46 to 73 percent coral cover for most of the previous two decades. Regional monitors reported Cordelia's cover falling to around 5 percent by early 2024. Stony coral tissue loss disease, which has spread through the Caribbean, was first confirmed on Roatan at Flowers Bay in September 2020.

On the other side, the Healthy Reefs Initiative's 2024 report card, covering 286 sites across the whole Mesoamerican Reef and based mainly on 2023 surveys, so largely before the worst of the heat, found reef health improving for the first time in five years, from 2.3 to 2.5 on its five-point index, still graded poor. Commercial fish biomass rose 40 percent and herbivorous fish 30 percent, and herbivorous fish improved across the Bay Islands except Guanaja. In 2025 the Roatan Marine Park and the California Academy of Sciences opened the Coral Restoration Center Roatan, the first land-based coral-rearing lab in Honduras, according to the California Academy of Sciences. Its first spawning, in June 2025, produced about 3,000 young brain corals, half of which went into protected tents on the reef, with the rest later moved onto the reef from the lab.

Who protects the reef?

Three layers. The Bay Islands National Marine Park, first created in 1997 and set in law by Decreto 75-2010, covers about 647,000 hectares around all the islands. The Sandy Bay to West End marine reserve, one of the island's first protected stretches of reef, has been co-managed by the Bay Islands Conservation Association since the 1990s. And the Roatan Marine Park, a community non-profit founded by dive operators and local businesses in 2005, runs patrols with the Honduran Navy, maintains mooring buoys, treats diseased coral and runs the lionfish culling licenses. It is funded partly by a voluntary contribution, sold as a reef bracelet, which some dive shops may mention when you book. Our guide to how healthy Roatan's reef is covers the state of the coral.

What are the rules?

In short: take nothing, spear nothing but lionfish, leave sharks and turtles alone, do not hold wildlife for photos, and keep your hands off the reef. Some of that is law, some is Roatan Marine Park rules, and some is simply what the island asks of visitors.

Do not take anything. Coral, shells with animals in them, conch, lobster, turtles and their eggs are all off limits. The Roatan Marine Park lists catching lobster and conch among the activities prohibited in the national park. Honduras also closes lobster and queen conch fishing nationally from 1 March to 30 June each year.
No spearfishing in the marine park and reserve, except licensed lionfish culling.
No sharks. Shark fishing has been banned in Honduran waters since 2011.
No holding sloths, monkeys, macaws and other named wildlife for photographs, under the ICF's 2025 notice.
Do not touch, stand on or feed anything on the reef. Touching or riding nesting turtles is illegal, according to the Roatan Marine Park. For the rest of the reef it is a request from dive operators and conservation groups rather than a written law, and it is the single biggest thing a visitor can do for the reef.
Sunscreen. There is no ban in force yet, although the Roatan Marine Park, with local partners, has petitioned the municipality to ban six chemicals, including oxybenzone and octinoxate. A mineral sunscreen, or a rash vest, is the considerate choice.

What about lionfish?

Lionfish are an invasive Indo-Pacific species that reached the Bay Islands around 2009 and eat young reef fish at a rate native predators cannot match. The response here has been to hunt them: the Roatan Marine Park trains and licenses divers to spear them, and lionfish is now on the menu at dozens of restaurants on Roatan and Utila. It is the one fish on the reef you are encouraged to eat.

Common questions about wildlife in Roatan

What animals can you see in Roatan?

Underwater, reef fish, hawksbill and green turtles, spotted eagle rays, southern stingrays, octopus and, with luck, seahorses and nurse sharks, plus Caribbean reef sharks on a specialist dive. On land, green iguanas, the endemic Roatan spiny-tailed iguana, agoutis and parrots. Sloths, monkeys and macaws are kept at animal parks but are not native to the island, and since 2025 holding them for photos has been banned.

Is Roatan part of the Great Barrier Reef of the Caribbean?

Roatan sits at the southern end of the Mesoamerican Reef, which WWF describes as the largest reef system in the Americas and the second largest in the world after the Great Barrier Reef in Australia. It runs about 1,000 kilometers through Mexico, Belize, Guatemala and Honduras. Roatan's reef is mostly fringing reef close to shore, which is why you can snorkel it straight from the beach.

Is the reef in Roatan healthy?

It has had a hard few years. Record heat between 2023 and 2025 caused severe bleaching, and one study recorded a 44 percent fall in live coral cover at three sites on Cordelia Banks. Coral disease reached Roatan in 2020. On the other side, the 2024 Healthy Reefs report card found regional reef health and fish stocks improving for the first time in five years, and a coral-rearing lab opened on Roatan in 2025. We still think the diving and snorkeling are well worth it.

Are there sharks in Roatan?

Yes, but you will rarely see one by chance, and they are not the dangerous kind. The sharks divers meet here are nurse sharks, usually resting on the bottom, and Caribbean reef sharks, seen mostly on the baited dive off the south side. Neither is considered a real risk to people, and we found no recorded shark bite on Roatan in modern times. Honduras has banned shark fishing since 2011.

When is the best time to see turtles in Roatan?

Any month, if you mean seeing them in the water. Hawksbill and green turtles feed on Roatan's reefs and seagrass all year, so snorkelers and divers meet them in every season. Nesting does have a season, roughly May to November, with hatchlings emerging about two months after the eggs are laid. It is small-scale, on quieter beaches such as Paya Bay and Camp Bay, and there is no hatchling tour to plan around. If you find a nest or a turtle on the beach, report it to the Roatan Marine Park.
