About 28 structural classes of alkaloids are known in poison dart frogs. [5] [22] The most toxic of poison dart frog species is Phyllobates terribilis. It is believed that dart frogs do not synthesize their poisons, but sequester the chemicals from arthropod prey items, such as ants, centipedes and mites – the diet-toxicity hypothesis.
An example of poison ingestion derives from the poison dart frog. They get a deadly chemical called lipophilic alkaloid from consuming a poisonous food in the rainforest. They are immune to the poison and they secrete it through their skin as a defense mechanism against predators.
The green-and-black poison dart frog, while not the most toxic poison dart frog, is still a highly toxic animal. The very small amount of poison the frog possesses is enough to make a human heart stop beating. [citation needed] The green-and-black poison dart frog, as with all poison dart frogs, loses its toxicity in captivity due to a change ...
Like most poison dart frogs, the yellow-banded poison dart frog has evolved aposematic colouration as a warning to potential predators that it will make an unpalatable or toxic meal. Predominantly, these frogs have a bright yellow colouration with varying numbers of broad black stripes and/or spots that extend over the whole body.
The dyeing poison dart frog (Dendrobates tinctorius), also known as the cobalt poison frog, tinc (a nickname given by those in the hobby of keeping dart frogs), is a species of poison dart frog. It is among the most variably colored and largest species of poison dart frogs, typically reaching snout–vent lengths of about 50 mm (2.0 in).
Oophaga solanensis is a large poison dart frog, with an average snout–vent length of 36.2 ± 1.7 mm (1.425 ± 0.067 in), although individuals can vary in length from 33 to 55 mm (1.3 to 2.2 in). O. solanensis have a dark black background color marked with variable orange or red spots and limb bracelets. In the typical color pattern, there are ...
Ranitomeya amazonica is a poison dart frog in the genus Ranitomeya. [3] It was first described by Rainer Schulte in 1999 as Dendrobates amazonicus when he separated it from Dendrobates ventrimaculatus, primarily on the basis of call characteristics.
This relatively large poison dart frog has a snout-vent length of up to 42 mm (1.7 in). [5]Gurupi Biological Reserve, Maranhão, Brazil. The best known variants of this species are black below and yellow, orange or red above, but its color is extremely variable with some having whitish-mint or light blue upperparts, some having a mottled or spotted pattern above, and some being almost all ...
