Mouthbrooders are fish or amphibians that take the fertilised eggs or hatched young into their mouths to protect them from predators.
There are two types of mouthbrooders: ovophilic and larvophilic. In ovophilic mouthbrooders, the "egg-loving" fish, the caring parent takes the eggs into its mouth during courtship. In contrast, larvophilic fish, the "larva-loving" fish, only take the hatched larvae into their mouths for brood care.
A distinction is also made as to which parent animal is responsible for caring for the fry. In the maternal care system it is the female, whereas in the paternal care system it is the male. If both parents are involved in brood care, this is referred to as biparental brood care.
Yes, once the guppies have been fertilised, they can store the sperm and use it for subsequent litters. This means that females that have been kept in an aquarium with males can still birth to young without males.
The mating organ of the males of most live bearing toothcarps is called the gonopodium. At the onset of sexual maturity, the male's anal fin transforms into the gonopodium. The anal fin of females resembles a triangle.
