Phyllosome (larva) of a spiny lobster, about 10 mm long.  It posses very long legs that are cut out of this photograph. 

When I was taking the picture, I thought that the small projection on the left was its head, followed by wider thorax with legs and then abdomen (right half of the photograph).  I was wrong.  After taking an undergraduate zoology course, I realized that this animal, as a larva, has a minimized abdomen that houses its anus.  Therefore, that small blimp on the left is the larva's abdomen.  To the right, is a "two-part" thorax, with legs at the rear (left) part of it.  Thus, I have completely left out its head.

Specimen collected during the 1996/1997 research cruises to the coastal waters of Barbados.
