One of these species, the Pelagic Thresher shark (Alopias Pelagicus), is known to inhabit the waters of Malapascua Island. The maximum length of Thresher shark is noted 6.1 meters yet. Fertilization and embryonic development occur internally; this ovoviviparous or live-bearing mode of reproduction results in a small litter (usually two to four) of large well-developed pups, up to 150 cm at birth in thintail threshers. All sharks are rare in Greece, and those that are seen or caught by fishermen are usually from less-dangerous types—basking sharks, thresher sharks, and dogfish. All sharks are rare in Greece, and those that are seen or caught by fishermen are usually from less-dangerous types—basking sharks, thresher sharks, and dogfish.

Many individual whale sharks have been approached, examined, and even ridden by divers without showing any sign of aggression. The young fish exhaust their yolk sacs while still inside the mother, at which time they begin feasting on the mother's unfertilized eggs; this is known as oophagy. Though they give live birth, Pelagic Threshers do not connect to their young through a placenta. The thresher shark is easily told from other sharks by the long upper lobe of the tail, which can be as long as the shark's body. Bigeye Threshers are normally the largest with Pelagic Threshers being the smallest. Scientists estimate that the life span of the whale shark ranges from 60 to 100 years. We do know that they are Viviparous, which means that eggs evolve in the uterus until birth. For the most part, they are rogue mavericks and remain largely independent. Bigeye Threshers are normally the largest with Pelagic Threshers being the smallest. Thresher sharks are not dangerous to people, in fact, we are lucky to have such an interesting predator living the Santa Monica Bay. The environments in which many thresher sharks species are known to live. But the exact habitat, again, remains largely a mystery.

University of Bologna - Italy. Thresher sharks reproduce each year and are. In addition to electro receptors that all sharks have, which gives them they ability to detect electrical impulses from living creatures, they also have an extraordinary heat exchanger system. In addition, they have slow-oxidative muscles centrally located within their bodies and a blood vessel countercurrent exchange system called the rete mirabile("wonderful net"), allowing them to generate an… These are very athletic sharks. Depending on the species, thresher sharks may be gray, blue, brown, or purplish. This is the primary concern with keeping large, pelagic sharks.

Like the fast-swimming sharks of the family Lamnidae, the common thresher has a strip of aerobic red muscle along its flank that is able to contract powerfully and efficiently for long periods of time. The thresher shark's behavior can be related to its location. Bigeye Threshers are normally the largest with Pelagic Threshers being the smallest. Sharks are common down to depths of 2,000 meters (7,000 ft), and some live even deeper, but they are almost entirely absent below 3,000 meters (10,000 ft). They favor the Pacific and Indian Oceans, especially at the continental shelves of America and Asia. Thresher sharks are found in tropical and temperate seas throughout the world.
