Although the primary investigation into the OPA anhydrases of squid tissue has been of the squid-type OPA anhydrase, squid does contain the more widespread "Mazur-type" OPA anhydrase. Gill, heart, mantle, and blood tissues all exhibit OPA anhydrase activities that are Mn2+-stimulated and hydrolyze soman faster than DFP (Hoskin et al. 1984). 

Because longitudinal resistance is inversely proportional to cross-sectional area, impulses are conduoted faster in large-diameter fibers. The squid axon is unmyelinated and exceptionally large (-800 pp) therefore, impulses are conduoted rapidly along it. Contraction of the mantle of a squid, however, is an uncomplicated procedure that does not require a complex sensorimotor system. Perhaps, during evolution, vertebrates developed a complicated input-output system of many fibers oollected in bundles, as shown in Figure 16.2. 

In the absence of a suitable commercially available artificial diet, five and fresh feed sources currently represent the most suitable vehicle for the administration of nutrition for the promotion of adequate growth and survival in phyllosomas. While phyllosomas will readily accept a variety of commercially available five and fresh feed sources, such as squid, mussel mantle and gonad, vlrfemia sp., oyster and clam, it is generally well accepted that Anemia sp. and mussel gonad, in combination, are the most common food sources for phyUosoma culture (Takeuchi and Murakami, 2007). However, fluctuations in the supply and nutritional quality of these feed sources results in an unreliable feed source, which potentially impedes the establishment of robust mass rearing protocols.
