And a rich grandmother at that, living in an air conditioned house instead of a broiling shack on stilts in the sylvan area of Ayutthaya. "Not yours, buddy; not yours," said a gecko that was crawling around his tomb within the train. "What?" asked Nawin, whining ingenuously. "The only panty hose that you have ever stroked are the ones you take off as a precursor to your copulatory sports."
The effect of the parasite in the male is that the abdomen is broader, the copulatory styles reduced, and biramous hairy appendages are developed similar to those of the female, but smaller. In the female the abdomen remains broad, but the appendages are much smaller than in the normal female, about equal in size to those of the 'sacculinised' male.
In Inachus the abdomen of the normal male is very narrow and has no appendages except two pairs of copulatory styles. The abdomen of the female is very broad, and has four pairs of biramous appendages covered with hairs, the normal function of which is to carry the eggs.
It need hardly be mentioned that the sexual peculiarities are not yet developed, and that in the males the hand-like enlargements of the anterior ambulatory feet and the copulatory appendages are still deficient. To the question, how far the development of Ligia is repeated in the other Isopoda, I can only give an unsatisfactory answer.
As I pointed out in my Sexual Dimorphism , the common characteristic of somatic sexual characters is their adaptive relation to some function in the sexual habits of the species in which they occur. All other differences, therefore, including genital ducts and copulatory or intromittent organs, are somatic.
As she stared at her creation she ruminated that nature was so foolishly wasteful in formulating these tenuous beings who spent a fourth or more of their lives trying to acquire sufficient knowledge so that they could begin to think for themselves, and thereafter most of their energies in copulatory obsessions so that they could replicate new know-nothings.
The conception of adaptation applies to these also, since we find that characters consist often of weapons such as horns, antlers, and spurs, used in sexual combat, of copulatory or clasping organs such as the pads on a frog's forefeet, of ornamental plumage like the peacock's tail serving to charm the female, or of special pouches as in species of pipe-fish and frog for holding the eggs or young.
