An Overview Of Nurse Sharks That Are Found In the Waters Around Cozumel
By Tom Seest
At TopCozumelNews, we help Cozumel tourists plan their trips and activities using information collected on trips to the beautiful island.
I’m not an expert on sharks, but I’ve done my research. I know that they’re apex predators, and they can be dangerous. But I also know that they’re not always looking to attack people. In fact, most shark attacks are caused by mistaken identity.
So, while I’m not going to go swimming with sharks any time soon, I’m not going to let my fear of them control my life. I’m going to enjoy the ocean and just be aware of my surroundings.
And if I do see a shark, I’m going to remember that they’re just animals, and they’re not out to get me. I’m going to stay calm and try to make myself look as big as possible. And if all else fails, I’m going to swim like a madman.
Palancar Reef is Cozumel’s premier snorkeling and scuba diving site with stunning coral formations like tunnels, caves, arches, swim-throughs, tunnels, and swim-throughs. Additionally, it is home to an abundance of marine life, including toad fish, turtles, eagle rays, and moray eels – perfect for both snorkeling and scuba diving!
Apex predator sharks don’t hang out here, but you may spot nurse sharks relaxing on the sea floor. There will also be plenty of smaller creatures here!

Cozumel’s warm and clear waters attract divers from all over the world, drawn there by vibrant coral reefs and diverse invertebrate life. Additionally, this is home to many shark species, including Atlantic nurse sharks.
These sharks are among the most frequent and least dangerous of those you might see during a dive in Cozumel, typically resting under rocks or ledges away from the potential danger posed by curious snorkelers and divers.
Although you might encounter numerous types of sharks during diving in Cozumel, you might come across something much larger and more intimidating – the bull shark. These large and intimidating animals resemble smaller versions of their cousin, the great white shark, in terms of size; should be provoked, they can be very dangerous indeed! Bull sharks are not commonly sighted around Cozumel, but some divers do encounter them at Cantarel, for instance.
Colombia Wall, a popular dive site featuring coral pillars and tunnels, is another spot where sharks can be found. Divers can expect to spot Blue Tangs, sea turtles, barracuda, and Caribbean reef sharks, among other marine life, while diving there.
Atlantic nurse sharks are one of the most frequently seen shark species on Cozumel and can be spotted year-round. However, its reefs also support an impressive array of marine life, from eagle rays and turtles to fish and more – you might even spot filefish triggerfish and colorful anemone-dwelling anemone shrimp!
Cozumel’s coral reefs stand out among Caribbean dive sites for being protected as national park reserves, meaning that they are well-preserved and full of marine life.
La Francesa and Dalila reefs are two excellent spots to spot nurse sharks. Look out for them, hiding out in cracks or crevices on rocky walls or resting on soft sandy areas of these reefs.
These quiet hunters primarily feast on soft animals such as fish, shrimp, and squid; however, thanks to their rows of tiny teeth, they can also consume coral or shellfish.
There’s one species of shark found near Cozumel reefs – though not natively here – which makes for an amazing diving experience: whale sharks. These massive predators typically frequent Playa del Carmen and Isla Mujeres waters but occasionally pop up off Cozumel too. Maple Leaf Scuba and other operators provide unique diving experiences where divers wear full-length dark wetsuits to enter and exit quietly from the water when diving with these massive fish.
Since nurse sharks are nonmigratory species, they can be found diving all year in Cozumel. As large bottom dwellers with a maximum length of 10.1 feet (3.08 meters), nurse sharks feed on fish and reef invertebrates – their daily diet comprises fish and reef invertebrates which they hunt day and night with two barbels attached on either side of their heads which allow them to skim the sand or reef floor looking for prey before lunging into it headfirst and swallowing whole! Their tough hide and tile-like scales ensure minimal damage from impacts when encountering potential obstacles during this encounter!
Nurse sharks are viviparous, meaning their eggs develop within the female nurse shark, and she gives birth when she’s ready. She can lay up to 30 eggs at one time. On average, nurse shark pups typically grow 4-6 inches annually.
Fearing swimming around sharks is understandable; however, it is important to remember that sharks do not attack humans. Any bite from a nurse shark usually results from harassment by a spear, hook, net, or hand, and its clamping bite is intended to deter further attacks by the aggressor. By remaining still, divers can reduce injury risks while simultaneously helping the shark relax so it can release itself from its tormenter.
Scuba divers who travel to Cozumel will experience an extraordinary underwater world that features the Mesoamerican Barrier Reef, one of the largest reefs in the Western Hemisphere and protected. Scuba divers are welcome to explore all corners of this wonderous reef while watching for its migration between January and March – which scuba enthusiasts are sure to witness first-hand!
Diving around coral reefs in Cozumel is filled with majestic sharks – and nurse sharks are some of the most harmless. But that shouldn’t cause panic: Cozumel offers many types of sharks for divers to encounter.
Nurse sharks have long cylindrical bodies with broad heads featuring small eyes and two barbels on their snout. They reach 14 feet in length with two dorsal fins. Nurse sharks use the side-to-side movement of their jaws to crush hard-shelled prey as well as filter feed, often sporting light yellowish-brown to dark brown hues with several small dark spots on them.
Squid are typically peaceful creatures that will shy away from divers unless they feel threatened or harassed, often resting on sandy bottoms or hiding under crevices and reef overhangs during day dives, while during night dives, you might spot one cruising through an isolated channel looking for food.
Blacktip Reef and Palancar Reef provide excellent opportunities for diving enthusiasts looking to see nurse sharks. Palancar Reef, in particular, boasts an incredible 3.5-mile-long reef full of caves, tunnels, archways, and swim-throughs that showcase a diversity of coral species – plus you may spot manta or stingrays that pose threats to the coral ecosystem. When diving here, it is wise to avoid interaction with these non-native invasive species as this would damage reef ecology and should be left alone!
Nurse sharks do not pose a threat to humans and should not cause alarm on a dive trip. Instead, these bottom-dwelling predators feed on fish, shrimp, squid, and shellfish and hunt alone using two fleshy growths on either side of their mouths (known as barbels) to search the reef or beach for food before sucking it up into their mouth where a cavity in their throat allows them to crush and chew soft shellfish and fish before swallowing whole.
On daytime reef visits, it is likely you will come across sea urchins lounging around, often hidden under outcrops of coral or submerged ledges where they rest. By nightfall, they hunt solitary, although occasionally you may come across small groups together – likely hiding from something. Their long tails – which make up as much as one-fourth of their total length – help conserve energy during hunting or swimming activities.
Nurse sharks may not be the primary draw of diving around Cozumel; you are more likely to encounter spotted eagle rays, sea turtles, and schools of colorful fish, as well as various varieties of coral such as table coral, sergeant major coral, and giant fan coral; Lionfish are also quite frequent as are moray eels and stingrays.
In the event of encountering a nurse shark near Cozumel waters, it’s essential that you remain calm and polite. These sharks tend not to be aggressive but will bite as a form of self-defense when provoked; should one bite you accidentally, any injuries from it likely only include minor cuts or puncture wounds.
At first glance, it can be captivating to witness all of the different species found swimming through the waters of the Caribbean Sea. Scuba divers especially delight in seeing nurse sharks and other large marine life like hammerhead sharks or whale sharks that reside there. Cozumel offers plenty of opportunities for viewing these impressive aquatic inhabitants!
Nurse sharks are beloved among scuba divers for their gentle nature. These slow-moving bottom dwellers are completely harmless to humans and often rest on sandy areas or rest in small crevices under ledges when not hunting for sustenance.
These sharks are so gentle that they’ve even been observed cuddling together on the ocean floor in “cuddle piles.” These beautiful animals are truly incredible to observe and should not be considered threats by scuba divers; however, it is important to remember that any wild animal may act unexpectedly; should one act aggressively, it is wiser to leave its area until later when it calms down before returning later when conditions have settled down again.
Sure, here’s a list of tips for individuals who might encounter Nurse Sharks:
- Stay Calm: If you spot a nurse shark, try to stay as calm as possible. Rapid movement or panic can attract the shark’s attention.
- Maintain Visibility: Always keep the shark in your field of view. If you can see the shark, you can predict its movements and react accordingly.
- Don’t Corner the Shark: Nurse Sharks, like most wild animals, are more likely to act defensively if they feel trapped. Make sure the shark has a clear escape route.
- Avoid High-Risk Areas and Times: Nurse Sharks are more active in the twilight hours (dawn and dusk) and in areas where their prey congregates. Avoid swimming during these times and in these areas if possible.
- Do Not Touch or Tease: Never attempt to touch, ride, or tease a shark. Not only is it dangerous, but it also contributes to the negative human impact on marine life.
- Bleeding or Open Wounds: Stay out of the water if you are bleeding or have an open wound. Sharks have a highly developed sense of smell and can detect blood from far away.
- Avoid Splashing: Try to keep your movements in the water as smooth and quiet as possible. Excessive splashing can mimic the movements of a wounded animal, which may attract sharks.
- Swim in Groups: Sharks are less likely to approach people if they are in a group rather than alone.
- Respect the Wildlife: Remember, when you enter the ocean, you are entering the home of countless marine species. Treat all sea life with respect and observe from a distance.
- Get Informed: Before you enter the ocean, get information about the presence and behavior of Nurse Sharks in the area. Local guides or authorities can provide valuable advice.
Always remember that shark attacks are extremely rare. Sharks are often misunderstood creatures that play a vital role in the ecosystem. Learning about them can help reduce fear and promote coexistence.
I’m no expert on sharks, but I know enough to stay out of their way. I’ve seen Jaws, and that was enough for me. I’m not sure what kind of waters sharks are drawn to, but I’m guessing it’s not the kind of water I want to be in. I’m more of a pool shark, myself.
I know that sharks are predators, and they’re not afraid to eat people. But I also know that they’re not mindless killing machines. They’re just animals trying to survive. So I try to give them the respect they deserve, even if I’m a little bit scared of them.
If I ever find myself in the ocean, I’ll be sure to keep an eye out for sharks. But I’m not going to let them ruin my enjoyment of the water. I’m just going to be careful and hope that they’re careful too.
