Chain Moray Eel GALLERYEchidna catenata
The pattern of black with the yellow chain-like markings are unique to each individual, like the stripes on a Zebra or the spots on a Leopard, or the fingerprints on your fingertips. They have rather thick bodies that do not taper-off towards the tail, giving them sort of a blunt tail. Most of these pictures were taken in as little as three feet of water. They may grow as long as 2.5 feet, but most of the ones I've seen are in the one to one-and-a-half foot length.
