There are those who pretend to be dead, those who exploit or hide sunlight and those who have learned to imitate the verses of prey: the most astute and brilliant techniques for getting lunch.
A HUNTING SUIT
The white- legged spider females (Misumenoides formosipes) change color, turning from white to yellow, to camouflage with the pollen of the flowers on which they patiently wait for their prey. The males do not seem instead endowed with the same chameleonic skills.
A THOUSAND BLUE BUBBLES 🐳
Humpback whales ( Megaptera novaeangliae) catch shoals of small fish with a technique known as a "bubble net". Once the prey has been identified, the cetaceans surround it, emitting air from the breather and creating a circle of bubbles from which the fish can not escape. At this point all that remains is to plunge with the jaws wide open. According to marine biologists, this ability - of which you see an example below - would not be innate, but transmitted from whale to whale.

STICKS AS BAITS 🐊
What is the first rule for effective hunting? Know the weaknesses of your prey. Some Indian swamp crocodiles (Crocodylus palustris) and American alligators ( Alligator mississippiensis ) know that and they have learned to wait for hours under the surface of the water, with sticks on their heads. The reptiles would seem to have sensed that, during the mating season, the herons would be looking for sticks for the construction of their nests. Hiding under the raw materials, lunch seems assured.
IMITATE THE VERSES OF THE PREY
The wily margay or cat of Wied (Leopardus wiedii, a wild feline of the forests of South America, has learned to reproduce the yelps of the bald tamarine cubs ( Saguinus bicolor). Animal attracted by the verses approach, going towards death.
TO PRETEND TO BE DEAD
The opossum is not the only animal that can pretend to be dead . An African fish of the Cichlidae family, the Parachromis friedrichsthalii, uses this trick to attract small fishes interested in its meat. The freshwater animal is positioned on the shallow water and remains motionless as if it were dead, for a period of time that reaches up to fifteen minutes. When the prey gets close enough, grabs them with a sudden click. In practice it uses it own body to act as bait. In doing so, however, it sometimes puts back shreds of fins.
