A large adult lobster's curiosity seems to override its instinct for self-preservation as it slowly approaches me from its hiding place under a coral overhang. After only a few seconds it will decide to back up, warily retreating to the safety of its lair. This pattern of advancing then retreating seems typical among these creatures, known as either "rock" or "spiny" lobsters. This colorful specimen has fuzzy growths of green algae on the tips of its legs. Coral overhangs such as this are also a good place to look for moray eels and even the occasional sleeping shark. Identification: Panulirus versicolor
