Decapod anatomy Decapod anatomy The decapod crustacean, such as a crab, lobster, shrimp or prawn, is made up of 20 body segments grouped into two main body parts, the cephalothorax and the pleon (abdomen). Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail: The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Maxillipeds are appendages modified to function as mouthparts.

Little hermit and some small insects. It feeds mainly by trap-lining. Little hermit The little hermit ("Phaethornis longuemareus") is a hummingbird that is a resident breeder in north-eastern Venezuela, northern Guyana, Suriname, French Guiana and Trinidad. This lowland species occurs in various semi-open wooded habitats, e.g. mangrove, secondary forest, plantations and scrub. In Trinidad it also occurs in rainforest. It is fairly common in most of its range, and therefore listed as Least Concern by BirdLife International. Previously, several other small hermits were considered subspecies of this species. This includes the stripe-throated hermit ("P. striigularis") of Central America and north-western South America,
