As the group circles a school of small fish such as salmon, krill, or herring, they use a team effort to disorient and corral the fish into a "net" of bubbles. [4] One whale will typically begin to exhale out of their blowhole at the school of fish to begin the process. [4] More whales will then blow bubbles while continuing to circle their prey.
Spider wasps paralyse and eventually kill their hosts, but are considered parasitoids, not predators.. At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; moreover, some relationships that result in the prey's death are not necessarily called pre

In passive electrolocation, the animal senses the weak bioelectric fields generated by other animals and uses it to locate them. These electric fields are generated by all animals due to the activity of their nerves and muscles. A second source of electric fields in fish is the ion pump associated with osmoregulation at the gill membrane. This ...

Gleaning is a feeding strategy by birds and bats in which they catch invertebrate prey, mainly arthropods, by plucking them from foliage or the ground, from crevices such as rock faces and under the eaves of houses, or even, as in the case of ticks and lice, from living animals.
