Members of the vertebrate group including anglerfish are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate.

Nematodes (roundworms) are distributed worldwide in almost all habitats. The Mermithidae, a family of nematodes larger than others, are obligate invertebrate parasites which occur in insects, ...

Distinguished by its unusual morphology and a reproductive system based on something called "sexual parasitism," the anglerfish represents a study in how life adapts to severe environmental ...

The parasitic wasp Dinocampus coccinellae is no fool. It controls a ladybug, lays an egg in its abdomen and turns it into the bodyguard of its cocoon. This surprising host-parasite manipulation has ...

When the cuckoo chick hatches, it ejects other eggs or hatchlings to get all the space—and food—for itself. Hungry as a whole brood, the outsize baby devours everything brought by its foster ...

Biologists have demonstrated that 'evolutionary experience' as well as learning protects cichlid fish from the brood parasitism practiced by the African cuckoo catfish. There are other animals besides ...

Scroungers and parasites seem to show up in nature wherever life produces something useful, and that includes parental care. Among birds, for example, the practice of laying eggs in other birds’ nests ...

This data set concerns the possible effects of brood parasitism on the species composition of a songbird community. Your instructor will give you directions about using this file to make figures ...

Here, we test the hypothesis that a caterpillar's host plant influences the identity of its parasitoid enemies and its probability of being parasitized. Our analysis includes a broad range of forest ...
