Crocodilia

The Crocodilia (or Crocodylia) are an order of mostly large, predatory, semiaquatic reptiles. They appeared 83.5 million years ago in the Late Cretaceous period (Campanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the crocodilian total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, a less ambiguous vernacular term for this group is crocodilians.

Large, solidly built, lizard-like reptiles, crocodilians have long flattened snouts, laterally compressed tails, and eyes, ears, and nostrils at the top of the head. They swim well and can move on land in a "high walk" and a "low walk", while smaller species are even capable of galloping. Their skin is thick and covered in non-overlapping scales. They have conical, peg-like teeth and a powerful bite. They have a four-chambered heart and, somewhat like birds, a unidirectional looping system of airflow within the lungs, but like other reptiles they are ectotherms.

Biography

Ridley was born in Bethnal Green, in the East End of London, where he lived and worked until moving to Ilford. Ridley studied painting at Saint Martin's School of Art and his work has been exhibited throughout Europe and Japan. He started as both a performance artist and the creator of a long sequence of charcoal drawings called The Epic of Oracle Foster. One drawing from this sequence, "Corvus Cum", portraying a man ejaculating a black bird, was exhibited at the ICA in London while Ridley was still a student and – with calls for it to be displayed behind a curtain – became a cause célèbre. Ridley also started his own theatre group as a student, acting in many of the productions, and made several short art films, including Visiting Mr Beak which starred the veteran actor Guy Rolfe. His short film for Channel 4, The Universe of Dermot Finn, was officially selected for the Cannes Film Festival, where it was a critical success and went on to receive theatrical distribution.
