The barracuda is widely spread across the oceans but is more commonly found in the more tropical regions where there is an abundance of food. Although barracudas can be found in the deep ocean, they tend to prefer coastal habitats along continental shelves and close to coral reefs.
The barracuda is an opportunistic predator, feeding only on other animals in the surrounding water. The carnivorous barracuda primarily feeds on smaller species of fish, marine invertebrates, crustaceans and squid, which the barracuda usually ambushes with tremendous power.
Due to the fact that barracudas can grow into very large sized fish, the barracuda has few natural predators in the ocean besides sharks and killer whales. Humans are also one of the barracuda's main predators as they are hunted and eaten all around the world.
Although little is really known about the reproduction of the barracuda, female barracuda are known to spawn during the spring. The female barracuda releases her eggs into the water which are then fertilised externally. As with many fish species, once spawned, the barracuda mother has no interest in caring for her young.
Today, due to it's aggressive nature, the barracuda is one of the most dominant predators within it's coastal environments and has even been known to act aggressively towards humans diving or snorkelling in the water.
