Opis:
The most toxic life stage of the eastern newt: the red eft is explained in this video and how its bright color aids in its survival. Rather than camouflage the eft stage advertises its presence with a bright orange/red color. The scientific name of the newt is Notophthalmus viridescens and also known as Eastern Newt or Eastern red-spotted newt or simply red-spotted newt. Warning colors of monarch butterflies, milkweed bugs, lady bugs, yellow jackets, bumblebees and even coral snakes are illustrated. This strategy of advertising toxicity or danger in biology is called aposematism. Aposematism includes a warning color to advertise an organism's toxicity, bad taste, spines, aggression, bad smell or any other negative feature.
