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. Particularly in the less advanced decapods, these can be
Cinnamon-throated hermit analysis by Hinkelmann where it merely is considered the male plumage of "P. nattereri". But as it seems, the Maranhao hermit only occurs in the northern part of the range of "P. nattereri", and as the two have different voices they seem to warrant recognition as distinct species "P. maranhaoensis". It is pending of confirmation by molecular work. Cinnamon-throated hermit The cinnamon-throated hermit ("Phaethornis nattereri") is a species in the hummingbird family, Trochilidae. It is found in a broad dry to semi-humid belt along the southern edge of the Amazon Rainforest from far north-eastern Bolivia north-east to Maranhão in Brazil.
