Other countries have at least banned shark finning, requiring fisherman to return with and use the entire carcass of a shark, which helps to reduce overall catch of sharks. Contrary to popular belief, sharks do occur around the coasts of Britain. This is the most widely distributed animal on the entire planet. Apex predators help to control populations of the different organisms that they eat, which generally allows for greater biodiversity, because competition between different prey species is not as intense with lower numbers of individuals. So do we need to fear these creatures from the deep or … Another issue with tracking blue sharks is due to their intense migratory patterns that were mentioned earlier. Worldwide in tropical to cold temperate latitudes, Order Carcharhiniformes (ground sharks), Family Carcharhinidae (requiem sharks). Since blue sharks are at the top of their food chain, they are very important in regulating the ecosystem in which they live. Human interaction. Only the belly of white sharks is whitish.

With this information you may be curious, why is the status of the blue shark so uncertain? Most of the data that we get on population numbers for sharks, and other marine organisms, comes from the “catch per unit effort” or CPUE; which essentially is number, or total weight, caught per amount of fishing effort (boats, hours fishing etc.) They were named for their blue color and are slender sharks that are usually 6-9 feet long (but can be 12-13 feet in length). White sharks are large bulky fishes with a body shaped like a blunt torpedo. They are born at around 14-20 inches long (35-50 cm), and they will reside in their “nursing grounds” for around two years before beginning to segregate, based on sex, and move to new habitats that better suit them. Many sharks are viviparous, meaning they give birth to live young. Additionally, there are some that claim orcas also feed on mature blue sharks, but the most commonly used report in this claim was unable to specify what exact species of shark it was… so the jury is still out.

Five sharks found in UK waters | Marine Conservation Society Its wide distribution and dense population structure makes the blue shark a target of fisheries in some areas and a common accidentally caught species in gillnet and longline fisheries targeting other species. Hammerhead sharks are viviparous: they retain fertilized eggs within the body and give birth to live young—from 2 to 42.
