Spanish Slipper Lobster (also known as Shovel-nosed Lobster)
Scyllarides aequinoctialisIf you see what looks like a moving rock with a couple large dark spots at mid-back, you've probably spotted one of these Slipper Lobsters. Hide during the day and forage at night. You may catch a glimps of one just after sunrise or a bit before sundown. They grow to about a foot long. They are pretty tolerant if you can approach them. I=one of these was in water about 3 feet deep, the other in about 10 feet. Not what you are looking for? Try the Spotted Spiny Lobster.
