 In March 2017, one crocodile shark washed ashore dead off the coast of Devon, England in Hope Cove, the first ever seen off the coasts of the United Kingdom.Thus far, it remains unknown as to why this particular shark was present so far north of its normal range.With a long body, small fins, and large liver rich in squalene and other low-density lipids, the crocodile shark is convergently similar to mesopelagic dogfish sharks such as the cookiecutter shark ("Isistius brasiliensis").
