To address this, we quantified arm regeneration and respiration in the Australian brittle star Ophionereis schayeri for 10 weeks...

Most of the few documented examples of four-stroke breathing among sarcopterygians are fully aquatic salamanders that lack robust gills, such as Cryptobranchus and Amphiuma , which apparently take advantage of a second two-stroke cycle to decrease the mixing...

Insect respiration is most easily monitored through measurement of CO 2 release, and three major respiratory patterns have been identified: discontinuous, cyclic or continuous gas exchange. Whereas some insects release CO...
