When people think of sharks they tend to think of the big ones, such as the great white or tiger shark, and are often surprised to learn that we have several species off the coast of the UK, including large, fast, predatory species such as the porbeagle and mako and the giant plankton-eating basking shark. Excluding the controversial great white, there are 35 species of shark and 26 species of skate/ray found in British waters.
An introduction to the Megamouth shark; its discovery and some of its poorly-known biology.
Sharks & Rays (Elasmobranchs)
Sharks, skates and rays (collectively “elasmobranchs”) are an incredibly diverse group of fish comprising almost 1,500 species worldwide.
Sharks are an ancient group of animals, but despite retaining many early characteristics are far from primitive.
Sharks are eaten by a variety of species, from gulls to whales. Humans are by far their biggest predator, however.
Small-spotted catsharks have been incorrectly referred to as "dogfish" for decades. Recently there has been a drive by marine biologists to set the record straight.
Marine mammals and fish have several adaptations to the shape, density and muscle configuration of their eyes that affects how light behaves upon entry.
Elasmobranchs have reinforced jaws that help cope with hard-shelled prey.
Elasmobranchs use a combination of an oily liver and lift generated by their fins to control their position in the water column.
Planktivorous species are feeding at the bottom of the food chain, allowing them access to vast quantities of potential prey.
The first sharks appeared in our seas about 400 mya, with the rays turning up some 200 mya later.
Oxygen availability may be the key factor limiting how large fish can grow and explain why mammals can outgrow them.
