These beautiful frogs are splashback poison dart frogs [Adelphobates galactonotus]. They are endemic to the southern Amazon Basin in Brazil. Though the specimens above share similar coloration, this species is highly variable between individuals. Some specimens may be solid white, or have green-blue markings rather than orange. Genetic testing has confirmed that despite appearances, these frogs are all members of the same species. Images by John White.
Here at Gettysburg Reptile Expo with a bunch of fun new things! New axolotls, gila monster, leopard and tokay geckos, skinks, and a bunch of salamanders! Come see me over at J14, from 9-4 today!
if you take requests could i request Dendrobates tinctorius (particularly the azureus or powder blue morphs) because i'm doing my dissertation on the genetic basis of colour variation between those morphs!!!
Batrachotoxins are a class of extremely potent neurotoxic alkaloids found in certain species of frogs, insects, and birds. These toxins work by permanently binding to sodium ion channels, blocking nerve signals to the muscles and causing paralysis. While these toxins are most famously present in poison dart frogs [“batreachos” is Greek for “frog”], the frogs themselves do not produce the toxin. Rather, poison dart frogs consume toxic insects, and repurpose the toxins in their skin for self-defense. For this reason, wild dart frogs are incredibly dangerous to touch, whereas captive-raised specimens are safe. The specimen shown here is Oophaga anchicayensis, an endangered species native to Colombia. Image by Cristian Gonzalez Acosta.
