The name "anglerfish" derives from the species' characteristic method of predation. Anglerfish typically have at least one long filament sprouting from the middle of their heads, termed the illicium. The illicium is the detached and modified first three spines of the anterior dorsal fin. In most anglerfish species, the longest filament is the ...
The humpback anglerfish uses a modified dorsal spine as a fishing rod with a bioluminescent lure to attract and capture prey. [1] A camouflaged predator: snow leopard in Ladakh. The distinction between aggressive mimicry and predator camouflage depends on the signal given to the prey, not easily determined.
In aggressive mimicry, predators or parasites resemble harmless species, allowing them to approach or to attract prey. [8] Anglerfish have a long filament (the illicium) sprouting from the middle of the head above the eyes and terminating in an irregular growth of flesh (the esca). The esca can be wiggled to resemble a small worm, luring other ...
The American anglerfish is an ambush predator. It spends most of its time on the seabed partly covered in sediment waiting for suitable prey to pass. It can swim slowly or "walk" with the help of its pectoral fins. Its diet normally consists of fin and ray fish, squids, cuttlefish and occasionally carrion. [4]
The plumage of the peacock increases its vulnerability to predators because it is a hindrance in flight, and it renders the bird conspicuous in general. [7] Similar examples are manifold, such as in birds of paradise [8] and argus pheasants. [citation needed] Another example of sexual dichromatism is that of nestling blue tits. Males are ...
Lophius was first proposed as a genus by Carl Linnaeus when he described Lophius piscatorius in the 10th edition of Systema Naturae given as "in Oceano Europæo", meaning the Northeastern Atlantic Ocean, Mediterranean and Black Seas with localities mentioned including Bordeaux, Marseille and Montpellier in France; Genoa, Rome, Naples and Venice in Italy; Lesbos in Greece; and Syria.
Emsleyan mimicry was first proposed by M. G. Emsley [2] as a possible explanation for how a predator species could learn to avoid an aposematic phenotype of potentially dangerous animals, such as the coral snake, when the predator is likely to die on its first encounter.
The unusual appearance of the frogfish functions to conceal it from predators and sometimes to mimic a potential meal to lure it in. In the study of animal behavior, this is known as aggressive mimicry. Their unusual shape, colour, and skin textures disguise frogfish.
