Kiribati has in fact already begun to export fish from Christmas Island and the fish are flown to Honolulu for sale in retail fish markets. Most of the fish that are exported at the present time are milkfish (Chanos chanos) from the interior lagoon, and spiny lobster from the reef flat - neither of which are ciguatoxic but other reef species make up part of the export.

The arthropod hemocyanins have yielded the most to diffraction studies. Studies of Limulus hemocyanin by Magnus and Love (1983, cited by Preaux and Gielens, 1984) showed a kidney bean-shaped subunit which is consistent with both electron micrographs and the structure of hemocyanin from Panuliris interruptus (spiny lobster). 

The deoxy forms of hemocyanins are colorless, as a result of their 3d ° dicopper(I) centers. Although chemical and x-ray absorption spectroscopic studies had shed considerable light on the nature of the deoxy-He dicopper binding site, there now exist two x-ray crystal structures, the first on the the spiny lobster He, Panulirus interruptus [23], and a recent one of the horseshoe crab Limulus II protein [24], The structures exhibit rather different active-site characteristics, and since the former was crystallized at low pH and possesses rather odd copper coordination, the latter Limulus II structure is probably representative. It indicates that the two Cu(I) ions are 4.6 A apart, each found in a trigonal-planar coordination environment with Cu-NMs bond distances of about 2.0 A (Figure 1). Intersubunit 02 binding cooperative effects are probably initiated and trans-...

Crustaceans are known to use pheromones in behavioral contexts other than avoidance, including reproduction and social interactions. For example, at least one spiny lobster, the California spiny lobster Panulirus interrupts, has been shown to be attracted to the odor of conspecifics.131 This pheromonal phenomenon is taken advantage of by workers in the lobster fishery, who use live lobsters as bait in their pots.132 However, relatively little research has been performed on the topic of aggregation pheromones, including the nature of the signal and its sensory reception. Pheromonal chemical signals are also involved in the establishment and maintenance of social hierarchies in crustaceans.133 134...

Hemocyanins (He) are oxygen-transport proteins found in the blood of insects, Crustacea and other invertebrates (MW 105-107) (20). One of the smallest He (MW 450,000) extracted from spiny lobster consists of six subunits, each containing two Cu atoms. Upon oxygenation, the deoxy-form (Cu(I), colorless) turns to blue (Cu(II), blue blood ) by binding one molecule of O2 per two Cu atoms. Freedman et al. (21) measured the RR spectra of oxy-Hc extracted from Crustacea and observed the v(02) near 750 cm-1, which shifts to 705 cm-1 upon 1602/1802 substitution. In contrast to oxy-Hr, the two O atoms of the coordinated O2 were found to be equivalent since...

Cleary the four alpha-helix bundle motif with the metal center can be seen. The three histidines coordinating Cu-A are colored red, those coordinating Cu-B green. The two copper atoms are colored blue and oxygen red. The cysteines binding covalently a histidine at the Cu-A site are colored yellow. In the case of Ipomoea, a water molecule connects the two copper atoms...
