Discuss techniques on observing the specimens using the senses of touch, sound, and sight. The intra- and extramitochondrial aspartate aminotransferases of two species from each of four classes of cchinodcrms (Holothuroidca, Echinoidea, This biotope complex occurs on wave-exposed, moderately strong to weakly tide-swept, circalittoral bedrock and boulders. Ossicles of arms are articulated in a streptospondylus manner. Plates of the internal skeleton may articulate with each other (as in sea stars) or be sutured together to form a rigid test (sea urchins).

Many tropical species are dark brown to black, but lighter colours, particularly yellows, are common among species not normally exposed to strong sunlight. Echinoderms are enterocoelous coelomates with pentamerous radial symmetry, without distinct head or brain having a calcareous endoskeleton of separate plates or pieces and a peculiar water vascular system of coelomic origin with podia or tube-feet projecting out of the body.
