The decapod (crustaceans 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 . [1] [2] Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail:
Lobster anatomy includes two main body parts: the cephalothorax and the abdomen. The cephalothorax fuses the head and the thorax, both of which are covered by a chitinous carapace. The lobster's head bears antennae, antennules, mandibles, the first and second maxillae. The head also bears the (usually stalked) compound eyes. Because lobsters ...

The cell on the left is going through mitosis and its chromosomes have condensed. Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis (transcription) occur.
Not from the actual human body, of course, but from the anatomical diagrams that purported to represent it. Goss was the esteemed editor of the 25th edition of the seminal classic Gray’s Anatomy . Internationally lauded as the authority on all things anatomical, Gray’s Anatomy had been considered essential for any would-be physician to own ...
The Lobster Conservatory includes information on the biology and conservation of lobsters. The majority can be applied to crayfish due to common ancestry and homology. Neural and tail anatomy provides an idea of the organization of the segmental ganglia in the tail of the crayfish. The second diagram on the page is a transverse section through ...
Dalí had already introduced the lobster as an erotic symbol in his 1936 surrealist object “Lobster Telephone,” and the following year, Schiaparelli offered him a new kind of blank canvas ...
