Starfish and abalone. Coloured X-ray of a starfish (class Asteroidea) and an abalone (Haliotis sp.). A starfish typically has 5 arms radiating outward from a central disc. Tube feet (not seen) located on the undersides of the arms are used for movement. A starfish does not have a brain. Instead,coordination is controlled by one or more rings of centrally-located nerves. An abalone is a mollusc,related to limpets and snails. Its flat shell contains a row of holes,through which inhaled sea water is expelled after respiration is complete. Several species of abalone are edible and are an important food source | |
