A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
As ambush predators, cougars silently stalk their prey with remarkable stealth. They mainly hunt deer in the mornings and evenings, and sometimes under the cover of night.
The following spring the nymphs emerge and seek out another host, often a small rodent. The nymphs become engorged and drop off the host in the fall to molt and become adults. The following spring the adult ticks emerge and seek out a larger host, often a large mammal such as cattle or even humans. Females will mate on their third host.
A white-headed dwarf gecko with tail lost due to autotomy. Autotomy (from the Greek auto-, "self-" and tome, "severing", αὐτοτομία) or 'self-amputation', is the behaviour whereby an animal sheds or discards an appendage, [1] usually as a self-defense mechanism to elude a predator's grasp or to distract the predator and thereby allow escape.
Frogfishes capture their prey by suddenly opening their jaws, with a mechanism which enlarges the volume of the mouth cavity up to 12-fold and pulls the prey (crustaceans, molluscs and other whole fishes) into the mouth along with water; the jaws close without reducing the volume of the mouth cavity. The attack can be as fast as 6 milliseconds.
Prey are typically caught while alive, and D. triton spiders are not repelled by sclerotization and metasternal secretions of potential prey. Juveniles tend to consume smaller prey than mature spiders do, especially females, who demonstrated a considerable lack of small prey capture, a trend attributed to the intense energy needs of yolk ...
Most of their body is black but they can have white areas on their bellies, pectoral fins, and the underside of their tails (flukes). In the above video, you can see that the whale has quite a lot ...
Nile crocodiles are apex predators throughout their range. In the water, this species is an agile and rapid hunter relying on both movement and pressure sensors to catch any prey that presents itself inside or near the waterfront. [1] Out of the water, however, the Nile crocodile can only rely on its limbs, as it gallops on solid ground, to ...
