RESPIRATION RATES OF SOME NEW ZEALAND ECHINODERMS (NOTE)

Abstract Respiratory iates were measured in four common New Zealand echinoderms, Evechinus chloroticus and Goniocidaris umbraculum (Echinoidea), and Coscinasterias calamaria and Pentagonaster pulcheilus (Asteroidea). Oxygen uptake was monitored with a polarographic oxygen electrode. The respiratory rates at 12°c ranged from 3.8 to 9.8 pi O₂.h^~!.g~> (live weight). The rates for Evechinus and Coscinasterias fall well within the range of metabolic rates of other echinoids and asteroids. Goniocidaris and Pentagonaster have relatively low respiratory rates.
