Expanded Information
Sea wolves can be up to 2 meters long and are aggressive. Their body is long cylindrical, mouth pointed, head like a shuttle, two dorsal fins far apart, the front dorsal fins have five spines, the rear dorsal fins have a spine and nine radial lines, the rear dorsal fins are the same size as the anal fins and are located directly above the anal fins. There are distinct lateral lines on both sides of the body, extending from the head through to the tail. They are also known as sea wolves due to their broad mouth jaws and possession of long, sharp teeth that protrude like wolf's teeth. There are 28 known recorded species of barracuda. Inhabiting the lagoon, the sea reef area or bay, daytime activities, solitary, belong to the migratory carnivorous fish, to fish, cephalopods, etc. for food. Mainly distributed in tropical and subtropical waters, more often found near coral reefs and sea grass, most barracudas live in the ocean, but some species of barracudas can survive in brackish water, such as the Barakin barracuda. The age of sexual maturity is 2-3 years for males and 3-4 years for females, and they regularly form large groups to spawn in harbors and estuaries every year, and the hatched fry drift with the tide to near-shore estuaries, where they remain at the confluence of brackish and fresh water to feed and grow. The mating season is usually in the spring, the male and female fish release sperm and eggs into the water, eggs and sperm in the water and fertilization to form fertilized eggs, the female fish can lay 1000 eggs at a time, but few eventually survive to grow into adulthood. Sea wolves can live up to 10-15 years, and most wonderfully and amazingly, we can tell their age by the number of rings on their scales and otoliths, just like the annual rings on a tree. Sea wolves are usually found near offshore reefs where they are easy to hunt, either singly or in packs. The sea wolf's two broad dorsal fins and forked tail provide them with strong forward momentum. They are fierce predators and will hunt by ambush, using high speeds to launch themselves at their prey, some of which are as big or even bigger than they are. Sea wolves are competitive by nature and often compete with other fish such as mackerel and sometimes even dolphins for prey. Their prey includes Czech fish, grouper, small tuna, _ fish, etc. The barracuda will simply and brutally bite them in half in one swift motion, or instantly tear the prey into pieces and swallow it. The sea wolf has been nicknamed the "Tiger of the Sea".
