Northwest warm temperate Atlantic Ocean - List of fishes

The caribbean sergeant major is a tropical fish associated with coral reefs and rocky tropical areas of the western Atlantic Ocean. This small schooling fish has a morphologically very close cousin throughout the Indo-Pacific region: A. sexfasciatus.

Commonly known as the porkfish, this species is native to the western tropical Atlantic Ocean. During the day, this fish seeks refuge alone or in small groups in crevices while actively hunting mollusks and crustaceans once night falls. Juveniles participate in cleaning sessions for larger fish.

Carcharhinus falciformis, known as the silky shark, is widely distributed in tropical and subtropical seas. However, this species is threatened due to overfishing, and is classified as vulnerable by the IUCN. Recognizable by its elongated and slender body, gray back, and white belly, this fast and aggressive predator feeds on fish, mollusks, and crustaceans.

The bull shark is listed in most tropical and subtropical seas. It is feared due to its propensity to attack humans, being responsible for most recorded fatal attacks to date. This active predator primarily hunts in murky waters. It is capable of swimming long distances and adapts to changes in salinity, frequenting estuaries, coves along the coasts, and waters with high turbidity.

Carcharodon carcharias, known as the white shark, is found in the coastal and oceanic waters of temperate and sub-tropical oceans and seas worldwide. A solitary predator, it feeds on fish, sharks, rays, and marine mammals, and can also scavenge on whale carcasses. With a keen sense of sight, it is curious and observant towards objects and activities. It is sometimes responsible for attacks on surfers.

The long-spine porcupinefish is a pufferfish found in the majority of tropical and subtropical marine areas around the globe. Juveniles can be found in small groups. As they age, this species becomes more solitary. Specialized in hunting mollusks and small crustaceans, this fish exhibits a seemingly clumsy swimming behavior.

The tiger shark is the third largest shark in the world. It is recognizable by its distinctive stripes along its sides, and by its short, flat snout. Tiger sharks are opportunistic hunters, known for their "bite-and-see" exploratory behavior to assess the nutritional value of their prey. These sharks generally prefer shallow waters, but can sometimes be found at greater depths.

The atlantic nurse shark is found in the Atlantic Ocean, from the Gulf of Mexico to southern Brazil. It spends most of the day resting under rocky shelters or in caves. This nocturnal predator feeds mainly on crustaceans, sea urchins, mollusks, and fish. It is oviparous and reaches sexual maturity at around 220 cm.
