Interesting Hunting Strategies Found in Nature

Humpback Whales and Bubble Net Feeding

One peculiar hunting strategy that humpback whales (Megaptera novaeangliae) use involves the coordinated effort of a few whales, a shoal of fish, and bubbles.  The technique starts with one whale singing an eerie, high-pitched feeding call beneath a shoal of fish while the rest of the whales circle the fish and release bubbles that creates a net-like barrier that disorients the prey.  The combination of high-pitched noise and bubbles drives the prey into a tight group near the surface of the water.  Then the fruition of this coordinated effort occurs when the whales swim together directly up through the middle of their gathered prey with their mouths open, thus yielding a hefty bite.  Now that’s teamwork!

The Stoat and the Freak-out

The stoat (Mustela erminea), also known as the short-tailed weasel, when hunting an animal such as a rabbit, which can be much larger in size, uses a technique that is sometimes informally referred to as the ‘weasel war dance.’  During this performance, the stoat flips around making erratic movements while also honing in on its mesmerized prey, eventually switching gears from the nutty neighbor to the hungry slayer.

Cats in the Cradle

The margay (Leopardus wiedii), a neotropical cat native to Central America, has been observed mimicking the vocalizations of rodents, birds, and even primates in order to attract its prey.  Cats are known for their physical agility, but this vocal manipulation of prey species indicates a psychological cunning which merits further study," said study researcher Fabio Rohe, of the Wildlife Conservation Society (WCS).
