The waters of Tampa Bay in Florida are home to a diverse array of shark species. Here are 8 of the most common types of sharks found in the bay and along the Gulf Coast.
The bull shark (Carcharhinus leucas) is one of the most common and well-known shark species in Tampa Bay. They are large, aggressive sharks that can tolerate fresh water and have been known to swim up rivers. Bull sharks get their name from their short, blunt snout and tendency to head-butt prey before attacking.
“The bull shark is probably the most dangerous shark in the world since it swims in very shallow waters and is found in rivers and estuaries.” 
Blacktip sharks (Carcharhinus limbatus) are fast, active predators that get their name from the distinctive black tips on their fins. They feed on small fish like mullet, croakers, and anchovies. Blacktip sharks are among the most abundant shark species in nearshore waters around Florida.
The lemon shark (Negaprion brevirostris) is a stocky, yellowish shark found in shallow subtropical waters. Lemon sharks give birth to live young and the bay provides ideal nursery habitat. These sharks eat fish, crustaceans, and other sharks. Lemon sharks got their name from their faint yellow coloring.
“Popular game fish like redfish, snook, and trout also attract lemon sharks looking for an easy meal.” 
Atlantic Sharpnose Shark
The Atlantic sharpnose shark (Rhizoprionodon terraenovae) is a small coastal shark reaching about 3 feet in length. They are abundant in estuaries and shallow waters of the Gulf of Mexico. Sharpnose sharks have a distinctly pointed snout. They primarily eat small fish, shrimp, and crabs.
The bonnethead (Sphyrna tiburo) is a small hammerhead shark found in shallow seagrass habitats. Bonnetheads are grey and reach about 5 feet long. They feed on crustaceans like blue crabs, shrimp, and squid. The unique, shovel-shaped head of bonnethead sharks allows them to find and dig out prey buried in the seafloor.
“Despite their appearance, bonnethead sharks are not considered dangerous to humans.” 
The spinner shark (Carcharhinus brevipinna) gets its name from its impressive aerial displays, leaping and spinning out of the water while hunting fish. They have slender bodies and long, pointed nose. Spinner sharks often follow schools of fish into shallow estuaries and bays. These fast-swimming sharks grow over 9 feet long.
The nurse shark (Ginglymostoma cirratum) is a large-bodied shark reaching over 10 feet in length. They are found resting on the bottom in shallow, coastal waters. Nurse sharks have small barbels that resemble whiskers near their mouths. They feed on crustaceans, fish, squid, and urchins. Nurse sharks are not aggressive towards humans unless provoked.
What is the most dangerous shark in Tampa Bay?
The bull shark is considered the most dangerous shark found in Tampa Bay due to its large size and aggressive tendencies. Bull sharks have been responsible for attacks on humans in the region.
Where are sharks most commonly found around Tampa Bay?
Sharks are most abundant along the shallow coastlines, in estuaries, and near underwater structures and reefs. The southwestern end of Tampa Bay near the mouth of the bay has a high concentration of sharks.

How can I identify different shark species?
Shark species can be identified by distinct characteristics like shape of the snout, fin markings, size, and behavior. For example, the hammerhead shape distinguishes bonnetheads, while blacktip sharks have dark tips on their fins.
In conclusion, Tampa Bay’s warm, shallow waters support a high abundance and diversity of shark species. While shark encounters are rare, it is important to be aware of the risks and know how to stay safe while enjoying Tampa Bay. Most sharks are not a threat if left alone.
