... in egg masses,using egg masses of the Antarctic nudibranch mollusk, Tritonia challengeriana . When warmed from –1.5° to +1.5°C, embryos of T. challengeriana showed large increases in O 2 consumption (Q 10 values of 9.6–30.0). Oxygen electrode measurements in intact masses showed, however, that O 2 levels...

... species of nudibranch molluscs: two Antarctic species ( Tritonia challengeriana and Tritoniella belli ; –1.5 and +2°C)and one temperate Pacific species ( Tritonia diomedea ; 12 and 22°C). D for all three species was approximately 8×10 –6 cm 2 s –1 , and there was no detectable effect of temperature...

... natural egg masses of a nudibranch and artificial egg masses made from sand dollar embryos and low-melting point agarose. Both temperature and embryo age strongly affected metabolic rates of nudibranch embryos. For embryos of a given age (stage), rates of oxygen consumption roughly doubled between 12...

...Stuart Thompson; Winsor H. Watson, III SUMMARY The nudibranch mollusc Melibe leonina swims by bending from side to side. We have identified a network of neurons that appears to constitute the central pattern generator (CPG) for this locomotor behavior, one of only a few such networks...
