Cadborasaurus willsi
"Caddy" has been given a scientific name by some overzealous cryptozoologists despite the fact that they have produced no type specimen as required by normal scientific procedures. It is, depending on who you ask, either a sea going reptile or a mammal similar to an extinct whale, but the evidence that it exists at all is very slight, and falls far below the standard of proof required by even the laziest zoologist.
