Aposematism Essays

In evolutionary biology, mimicry can be defined as a similarity of one species (the mimic) to another (the model) as a protective mechanism for either one or both species, against another species (the signal-receiver or the audience), typically a common predator of both species. The stimulus occurs as appearance, behaviour, sound or scent. The model is usually another organism, with the exception of automimicry. For prey species, mimicry strategies evolved as an adaptation against predators within

The Choco Indian rolled the dart tip on the Golden Poison Dart Frog 's back. Then he inserted the dart into the blowgun, ready for his dinner. The poison of the Poison Dart Frog has been used by the Choco Indians since ancient times. The Choco Indians would use the Golden Poison Frog 's poison by exposing the frog to heat. They then would lace their darts and arrows with this toxin. Although the Poison Frog might seem like a menace, its habitat, prey, and toxin can all be adjusted so that the frog

It has an irregular V-shaped canopy. The bark is black, it has white flower-balls and flat sickle-shaped pods (Eco Travel Africa, n.d.). The thorns have aposematic colouring. Aposematism is the use of bright colours to advertise that an organism is dangerous or unpalatable (The Amateur Entomologists' Society, n.d.). The conspicuous colour of the thorns becomes a visual sign to animals who would attempt to feed on it (Lev-Yadun,

Poisonous Animals The cane toad is an invasive species that came from Hawaii to Australia to eat the cane beetles. The cane beetles were causing a big problem as they were eating Australia’s sugar cane. Once introduced to Australia, the cane toad multiplied until its numbers reached up to 200 million. The toad eats snakes and lizards. The cane toad’s main defense mechanism is its toxin. It has parotid venom-secreting glands that are present at all times. Even from the time a cane toad is an
