This pair of Palechin Moray Eels (Gymnothorax Herrei) could be found together, inhabiting the same crevice at Sail Rock for a number of weeks.

Presumably they felt less threatened in this crevice as they were far less concerned about being photographed than when they are found on the rock face.

In this photo it is easy to see the rows of tiny sensory pits, common among Morays, that line the snout and jaw area. Since Morays are generally nocturnal hunters, and have particularly poor eyesight, these aid the Moray in detecting prey.
