A LARGE LOBSTER

Lobster claw leg.

His right leg was shorter than the left and ended in a conical stump. The foot had a well developed big toe and rudimentary second toe, and was located halfway up the lateral aspect ofthe leg (Fig. 1). The lateral three toes were absent.

The Vitamin a of the Lobster

In many crustacea, including the lobster, the bulk of the vitamin A of the whole animal is concentrated in the eyes. Recently Fisher, Kon, and Thompson found that vitamin A extracted from the eyes of euphausiid crustacea has only about one half the biological potency of the same amount of the all-trans acetate or fish liver vitamin A. In the present experiments the vitamin A of the lobster eye ...

Lobster olfactory genomics.

Lobsters have numerous adaptive specializations of the olfactory system that make them especially suitable model organisms for the study of olfaction. Recent work using genomics and physiological genomics to study the lobster olfactory organ extends the advantages of their use further. A subtracted cDNA library from the mature zone of the olfactory organ and 3 physiological genomics experiments...

Biological Basis for the Protection of Large Lobsters in Lobster Fishing

In October 2007, the Regional Director-General (RDG), Maritimes Region, announced a number of priorities for the Maritimes lobster fishery, including improving conservation measures to provide better protection for large mature female lobsters in particular. At a meeting with the lobster industry in September 2008 to discuss potential new measures, industry raised questions about the biological...
