‘In addition to the 21 resident sharks, there are at the least 11 deepwater shark species together with the Portuguese Dogfish, Black Dogfish, Kitefin Shark and Gulper Shark,’ The Sharks Belief explains on its web site. 

Clean hammerhead shark

The Clean Hammerhead Shark has a broad distribution worldwide however prefers temperate waters. 

It’s a really uncommon sight in British waters, but when one does seem, it would almost definitely be within the North Atlantic, off the coast of the western tip of Cornwall. 

The hammerhead shark household is made up of 9 species, which all have distinctive hammer-shaped heads. 

As its identify suggests, the sleek selection has a extra rounded head form than different species. 

In 2019, a clean hammerhead shark was noticed within the Celtic Sea, about 100 miles south west of Eire – the furthest north the species has ever been seen in British waters. 

Consultants say the lone specimen may have been misplaced however most likely ventured additional north than regular as a result of oceans getting hotter.

Dr Paul Connolly, director of fisheries and ecosystems providers on the Marine Institute stated: ‘That is an thrilling encounter, particularly since a uncommon deep-water shark nursery, 200 miles west of Eire, was found by Irish scientists final 12 months.

‘This sighting of a brand new shark species, reveals the significance of our fishery surveys to observe our marine setting, and to watch modifications in our oceans and marine ecosystems.’

Based on consultants, there have been no recognized fatalities from hammerhead sharks wherever on the earth to this point.

Future charges of warming threaten marine life in additional than 70 % of essentially the most biodiverse elements of Earth’s oceans, new analysis reveals. 

The researchers used a brand new method to check previous and future extremes of ocean warming, which allowed them to map worldwide publicity to future local weather change and decide distances that species would want to maneuver to seek out higher local weather situations.

‘Our analysis reveals that areas with exceptionally excessive marine biodiversity are essentially the most uncovered to future oceanic warming, making them significantly susceptible to twenty first century climatic change,’ stated lead creator Dr. Stuart Brown from the College of Adelaide’s Setting Institute in a press release.
