The well-made video, beautiful voice acting, magnetic commentary by the yoga master, coupled with the graceful longtail shark swimming posture, make people feel an impulse to be close to the longtail shark. In the face of such a beautiful creature, do you have an urge to embrace it and protect it?
Here's a quick compilation of some basic information about the longtail shark, hoping to help you understand this charismatic shark. There are three species of longtail sharks known worldwide:
Shallow longtail shark (Pelagic Thresher)
Bigeye Thresher
Slender-tailed long-tailed shark (Common Thresher)
A few facts about the longtail shark:
The tail of the long-tailed shark can reach up to 6 meters!
The long tail or tail fin of the longtail shark resembles a threshing machine, accounting for half of its body length. They are active predators, and their tails are actually used to stun prey. Until now, the largest species are slender-tailed long-tailed sharks, which can reach 6 meters in length and 400 kilograms in weight, respectively. The big-eyed longtail shark is the second largest, about 4.9 meters long, while the smallest shallow sea longtail shark is 3 meters long.
The tail of the long-tail shark is often used to stun prey, surround the fish, and stun you with its tail! This is the secret weapon of the longtail shark!
The long-tailed shark is juvenile , with a short snout on its head , a small dorsal fin , and a long upper lobe of the pectoral fin that curves backwards. With the exception of the big-eyed long-tail shark, other long-tail sharks have relatively thin eyes. The back is brown, grayish blue, or grayish green, and the abdomen is lighter. Three species of long-tailed sharks can be distinguished by the color of their backs: the slender-tailed longtail shark is dark green, the big-eyed longtail shark is brown, and the shallow sea longtail shark is blue.
The longtail shark is an impressive hunter
Longtail sharks are very attractive predators and like to prey on schools of fish. They use unique tails to help lure prey. Once the prey is near them, they will repeatedly slap the prey with their tails until it is destroyed. It then attacks its prey at speed, biting on each launch until it completely devours its prey
Long-tail sharks are warm-blooded: Long-tail sharks are one of the few shark species with heat absorption ability.
They have a slow exchange of oxidative muscles and vascular countercurrents, which helps them regulate blood pressure internally. This makes their blood 2 degrees Celsius warmer than the surrounding water. Warm-blooded animals can stabilize their proteins in colder water, helping them use muscles more efficiently. Their ability to absorb heat makes them agile hunters and agile swimmers.
The longtail shark is the fastest shark in the ocean and can swim at a top speed of 30 miles (48.2 kilometers) per hour
They swim so fast because of the extra thrust of their long tail fins, their ability to absorb heat, and having an aerobic red muscle on either side that helps it gain extra strength and strength. The body of the longtail shark is also torpedo-shaped, which can reduce the resistance of water to the body.
Longtail sharks are less of a threat to humans, with only one record of longtail shark injuries to date.
The injury is also recorded as a case of a diver grabbing the tail of a long-tailed shark and being injured by its tail
Longtail sharks prefer deep-sea and open oceanic waters: Although they breed along coastal waters, juvenile longtail sharks stay in shallower waters until they mature, preferring deep, open waters.
Most of their time is at a depth of 550 meters. Migrate north to spend the summer and winter in the south. They prefer tropical and subtropical waters, but migrate to temperate waters to hunt. Although long-tail sharks sometimes occur in shallow and nearshore waters, they are mainly found in the oceanic zone. They live about 500 meters in bodies of water. Slender-tailed long-tail sharks are more commonly found in coastal waters than in continental sheds. In the North Pacific, the slender-tailed longtail shark is found in continental sheds along North America and Asia. In the warmer central and western Pacific Oceans , slender-tailed longtail sharks are rarer , while large-eyed longtail sharks and shallow sea longtail sharks are more common.
Predation habits:
The longtail shark feeds mainly on pelagic bands such as flat trevally, tuna and mackerel, squid and squid. They track schools of fish to shallow water. They also eat crustaceans and seabirds. The long-tail shark will use its tail to surround the fish, and then use its tail to knock the fish unconscious or shoot to death, and then hunt.
Several famous diving destinations for the longtail shark can be seen:
Malapascua Philippines (Mom Pats Loofah): Known worldwide for its longtail shark dive site. It claims to be the only place in the world where longtail sharks are likely to be seen every day.
Layang Island, Malaysia: Depending on the season, good luck can see longtail shark tracks around the island.
Hurghada and Marsa Alam of Egypt
Around Bali Island in Indonesia
Around the Indonesian island of Alor
