An Overview Of Hammerhead Sharks That May Be 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 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.
Cozumel is one of the world’s premier diving destinations, boasting stunningly colorful reefs full of marine life.
However, seeing sharks on every dive may not be guaranteed; nurse sharks are frequently encountered at many dive sites on the islands.

Though they are rarer, hammerhead sharks can occasionally be seen around Cozumel’s reefs. While bonnethead or shovelnose sharks are more frequently seen here, hammerheads stand out due to their unique appearance – with their saw-like snout, blunt head with saw teeth, olive to brownish-grey coloration, and an array of rings, ovals, and loops on their dorsal surface, maximum size estimated to be 4 feet long.
White sharks, an endangered species, can occasionally be seen swimming through our waters. With their characteristic bullet-shaped bodies and cone-shaped snouts topped by lunate caudal fins (shaped like crescent moons), these sharks usually only venture into shallower water during winter.
Nurse sharks, which you are likely to come across on our dive sites, are harmless bottom-dwellers with powerful jaws for crushing shellfish and devouring them whole. You will likely encounter these gray-brown creatures during dives on our dive sites. They are commonly found resting on sandy bottoms near underwater ledges, crevasses, or tunnels, where they spend most of their time resting before devouring it themselves!
Bear in mind that only 17 unprovoked shark attacks against humans have ever been recorded in Cozumel waters, but it is always wise to be cautious when diving here or elsewhere.
The hammerhead shark is one of the ocean’s most effective predators. These massive sharks live alone in isolated groups, tracking down and hunting helpless prey at night. Although incredibly tough, some may only live for 30 years in their natural environment before dying off or being relocated elsewhere.
The world’s largest hammerhead sharks can be found swimming near tropical shorelines or along shelves worldwide, where they feed on an assortment of organisms that include bony fish, squid, octopus, crustaceans, and even our beloved sting rays (they specialize in ramming them with their unique design before devouring them!).
Cozumel’s national marine park may not regularly see hammerhead sharks, but divers may still encounter Atlantic nurse sharks, black-tip reef sharks, and scalloped hammerheads on certain dive sites. There have also been reports of bull sharks at Los Arcos for snorkeling enthusiasts.
Though shark sightings on Cozumel may not be common, El Cielito dive site is known for the magnificent spotted eagle rays which migrate through this section of Mesoamerican barrier reef between January and March each year, providing divers with an incredible chance to observe these magnificent creatures as they skim along the surface and gather clouds of sand with their wings-like pectoral fins.
Bull sharks are found worldwide in shallow, warm water. These predators have an array of prey that includes other sharks, fish, crustaceans, and squid. Sometimes even taking on sting rays and turtles, though rare human attacks have been recorded.
Bull sharks can often be found near Cozumel on dives and are one of the few types that can be seen close to shore.
At Devil’s Throat on Cozumel’s east side, snorkel or scuba dive among these massive beasts in its dark tunnels teeming with brightly-colored coral and eagle rays for an incredible underwater experience.
At Cozumel, other shark species you could encounter include Atlantic nurse sharks – year-round residents in its reefs and visible on dives of varying depths – that can often be found curiously approaching divers on dives. At certain times of the year, you might also see whale sharks – filter feeders which grow up to 60 feet with their large flat heads recognizable by divers.
Hammerhead sharks are among the most specialized predators in the ocean. They possess incredible hunting and destructive capabilities and can consume anything in their territory, including fishes, other sharks, crabs, squid, and lobsters – as well as inflicting a vicious bite when necessary.
Hammerhead fossil records date back 23 million years; some experts speculate they first appeared even earlier. Hammerheads are considered among the newest of all shark groups to appear and exhibit diverse behaviors, including swimming in schools during the day and hunting alone at night.
Octopuses can be found around the globe in warm tropical waters near coasts and continental shelves, where they feed on fish, crustaceans, squid, octopus, and their favorite meal: stingrays! Their unique hammerhead design enables them to use forceful attacks against them before eating away at them piecemeal.
Hammerhead sharks are not unusual sights around Cozumel waters, making diving sites like El Cielo, Isla de las Golondrinas and Barracuda Reef the ideal places for divers to witness these powerful predators in their natural environment. Take this chance and witness these magnificent predators up close!
While they can be found globally in warm temperate waters, hammerhead sharks tend to prefer shallow coral reef environments with sandy bottoms and sandy surfaces for hunting. Hunting either alone or in schools, they eat various species of fish as well as squid, octopus, crustaceans, and other marine life they come across – including other sharks of their own species! In contrast to aggressive bull sharks, however, smooth hammerheads have never attacked humans without provocation.
The Great Hammerhead inhabits coastal regions in tropical and warm waters worldwide, often found along continental shelves and lagoons. As an apex predator, they prey upon marine species such as stingrays using their large, hammer-shaped heads to pin them to the ocean floor before feasting upon them like crabs.
Cozumel waters are home to this massive, migratory fish species known as a giant grouper that can reach 60 feet long, boasts a distinctive humped back with ridges, and has an enormous flat head. Divers and these playful giant fish alike will find it exciting and inquisitive creatures to watch, with flashing strobes or sudden movements often surprising these curious fish; however, they may become startled by bubbles from diver’s air tanks; therefore, it is important to remain calm while following your dive guide’s instructions to witness one!
Cozumel’s waters are home to many aquatic creatures, from sharks and whale sharks to fish, rays, and turtles. You might even spot one of Cozumel’s majestic whale sharks – they can reach 60 feet long! Their flat heads with ridges allow them to feed on plankton while moving slowly through the waters grazing on plankton. Other common marine creatures found there include slow-moving nurse sharks with broad heads known for using their jaws to remove shellfish fragments with ease!
The Great Hammerhead Shark can often be found cruising Cozumel waters. While usually shy, this powerful predator has been known to approach divers when curious. Unfortunately, this species is heavily fished for its dorsal fin and is listed as Endangered by IUCN.
This April, Carlos Roberto Castro Tadeo captured a video showing a hammerhead shark chasing a stingray through the clear waters near Cozumel. It was posted on Storyful and claimed by the boat captain on board that they had never before witnessed such an encounter! Interestingly enough, Carlos noted he had never witnessed such shallow water conditions with such a shark present before!
Though sharks pose a danger to humans, their presence also helps ensure species further down the food chain don’t overpopulate and keeps our coral reefs healthy. When encountering one of these fish, it is important to stay calm; jostling could make the shark mistake you for prey and may lead them to investigate further. Instead, slowly swim away while maintaining eye contact, if possible, with it.
Cozumel waters are home to several species of sharks, such as Great Hammerheads, Scalloped Hammerheads, and Bonnethead or Shovelnose Sharks. Each shark type bears a unique head shape associated with its name but differs in terms of size and other characteristics.
On April 15, 2022, one of the most remarkable interactions with sharks occurred when a hammerhead shark chased and then devoured a stingray to the amazement of a boatload of tourists. It was an impressive display that demonstrated that sharks can be scary but are part of our marine environment and should be respected as such.
Sure, here’s a list of tips for individuals who might encounter Hammerhead Sharks:
- Stay Calm: If you spot a blacktip 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: Hammerhead 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: Hammerhead 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 Hammerhead 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 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.
