Cnidarians occupy a key evolutionary position as basal metazoans and are ecologically
important as predators, prey and structure-builders. Bioregulatory molecules (e.g.,
amines, peptides and steroids) have been identified in cnidarians, but cnidarian signaling
pathways remain poorly characterized. Cnidarians, especially hydras, are regularly used
in toxicity testing, but few studies have used cnidarians in explicit testing for signal
disruption. Sublethal endpoints developed in cnidarians include budding, regeneration,
gametogenesis, mucus production and larval metamorphosis. Cnidarian genomic
databases, microarrays and other molecular tools are increasingly facilitating mechanistic
investigation of signaling pathways and signal disruption. Elucidation of cnidarian
signaling processes in a comparative context can provide insight into the evolution and
diversification of metazoan bioregulation. Characterizing signaling and signal disruption
in cnidarians may also provide unique opportunities for evaluating risk to valuable
marine resources, such as coral reefs.

Montie, Eric W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-09)Cetacean blubber is a primary site for lipid storage, which the animal utilizes during periods of energetic stress. It is important to understand how the blubber responds to factors such as ontogeny, water temperature, ...
