September 27th: Male Strategies and Assessment
Males of many species come in alternate morphs. For example the image
here shows an African Cichlid, Lamprologus callipterus. In this species,
males are either large "nest males" who collect shells in which
the female will lay her eggs, and the very small "dwarf males" hide hoping
to sneak a mating with the female. (for more detail see Taborsky, 2001)
