چکیده

Carotenoids and their fatty acid esters in the carapace of the spiny lobster Panulirus japonicus were investigated. Fatty acid esters of astaxanthin, adonixanthin, and pectenolone were characterized by (1)H-NMR and FAB-MS. The acylated position of adonixanthin and pectenolone monoesters was determined to be a hydroxy group at C-3' by (1)H-NMR. The fatty acids esterified with these carotenoids were identified as C22:6, C20:4, C20:5, C18:0, C18:1, C17:0, C16:0, C16:1, C14:0, and C12:0 from FAB-MS spectral data. Furthermore, 2,3-didehydrocanthaxanthin (4) was first identified as a natural product.

Neurodynamic control of the heart of freely moving spiny lobster (Panulirus japonicus)

The heart of the crustaceans has its own pacemaker neurons inside the heart, which are composed of 9 neurons. The neurons receive innervations of only three kinds of axons originated from the central nervous system; one pair of inhibitory and two pairs of acceleratory axons. Thus, in terms of the neural cardiac control from higher center, this system may have much more simplistic operation comp...

Neurolipofuscin is a Measure of Age in the Caribbean Spiny Lobster, Panulirus argus, in Florida

Accurate age estimates for the commerciallyimportant Caribbean spiny lobster, Panulirus argus, would greatly enhance analyses of life history and population dynamics. Previous estimates of their age based on size and growth may be inaccurate because of variable growth in the wild. An established technique for aging crustaceans – histologically-determined lipofuscin content in the nervous system...

Behavioral responses to variable predation risk in the California spiny lobster Panulirus interruptus

Shelter dwelling and gregariousness are behavioral strategies used by benthic marine organisms to reduce the risk of predator-induced mortality. For spiny lobsters, the relative and synergistic success of shelter dwelling and aggregation in reducing mortality may vary with the perceived risk of predation as well as the availability and size distribution of conspecifics and shelters. We tested h...
