All of the larvae and adults are carnivorous and predaceous (except the parasitic Sisyridae), devouring enormous numbers of mites, insect eggs and larvae, ants, thysanopterans, psocopterans, and homopterans.
Neuropteran eggs and larvae are preyed upon by other neuropterans, other predaceous insects (e.g., coccinellid, or ladybird beetle, larvae, ants), birds, and bats.
The larvae are predaceous, usually nocturnal, and may leave the water to search for prey or to molt.
They were the dominant reptiles of the Permian Period (299 million to 251 million years ago), and, although they were primarily predaceous in habit, the adaptive radiation included herbivorous species as well.
Dental features are particularly well suited for this important role in classification because they reflect the broad radiation of mammalian feeding specializations from the primitive predaceous habit.
All amiiform fishes (that is, the bowfin's extinct relatives) were probably predaceous.
There is increasing evidence that food is not a limiting factor on summer bird populations in the Arctic, except in the case of strictly predaceous species during years of scarcity of prey.
Spanning several species, tigerfishes are so named on the basis of their pugnacity when caught, their fiercely predaceous habits, or their appearance.
Predaceous diving beetle (family Dytiscidae), also called diving beetle, or true water beetle, any of more than 4,000 species of carnivorous, aquatic beetles (insect order Coleoptera) that prey on organisms ranging from other insects to fish larger than themselves.
Mesoveliids are predaceous and are usually seen on floating vegetation or on the water surface.
The earliest mammals were small, active, predaceous, and terrestrial or semiarboreal.
