barracuda with dull teeth

the great barracuda is the biggest species of barracuda, reaching over 5 ft (1.5 m) in length. great barracudas inhabit the tropical and subtropical reef waters throughout the world from depths of 0 to 330 ft (100 m) they are carnivores that mainly hang out in shallow water close to shore and feed on other fish with their two rows of needle-like teeth. barracudas will hover almost motionlessly in the water and dash at prey that swims by with a single burst of speed. prey is located visually with their very good eyesight. great barracudas normally travel alone, but they have been


observed swimming in large groups in order to circle and trap schools of small fish. their compressed bodies are designed for speed. they can reach speeds of up to 35 mph (56 km/h) in short bursts. large barracudas are notorious for accumulating a toxin in their tissues called ciguatera. this makes them very unpopular for human consumption. ciguatoxin can make humans sick or even cause death if these fish are eaten. female barracudas can release over 500,000 eggs into the water when spawning takes place. juvenile barracudas take shelter from predators in mangrove forests and sea grasses


until they are a year old. their lifespan is around 14 years. great barracudas can be distinguished from other species by the black spots on their sides. their predators include dolphins and sharks. in rare instances barracudas have attacked humans. this is usually the result of mistaking something shiny, like an earring, for a small fish. for more marine facts, click the subscribe button!!
