Abstract
The poeciliid fish Poecilia mexicana successfully colonised a sulfur cave in Tabasco, Mexico. The eye size, melanin pigmentation and scale tuberances as well as aggressive and schooling behaviour are reduced in the cave fish. Besides these regressive characters some constructive ones have been found. The genital region of the female is enlarged to a genital pad and in both sexes the number of taste buds is considerably increased on the upper side of the head. The cephalic lateral line shows a hyperdevelopment with an incomplete covering of some channels. Nearly all of these characters studied form a genetically based gradient from the beginning to the end of the cave, which seems to be the result of gene flow from the outside to the inner part of the cave. A special behavioural adaptation was found among females which prefer bigger males during courtship. In darkness, only the cave females show this preference.
