Oxygen consumption in echinoderms from several geographical locations, with particular reference to the Echinoidea.

1. "Whole body oxygen consumption data are determined for a variety of echinoid, asteroid and holothuroid species, and for one ophiuroid and one crinoid.2. Comparisons of tropical and temperate asteroids indicate no correlation of oxygen consumption rate with environmental temperature among the individuals tested. As is the case for echinoids. body size appears to be an important factor in determining the Qo2 of a particular species.3. Whole body oxygen consumption data are determined for several temperate and tropical echinoid species, and for a deep-water echinoid of the Pacific Coast.4. A comparison of respiratory physiology in S. purpuratus and A. fragilis is made, with particular attention to the body wall and gonad indices.5. Comparisons of tropical and temperate echinoid oxygen consumption rates reveal that, when animals of similar size are compared, the Qo2 of the tropical forms is similar to that of their temperate counterparts.6. The generally smaller body size of the tropical species tested res...
