Big brains are very useful, but they cost ENERGY and RESOURCES, at least for mammals and birds. Now a new study has shed light on what determines whether reptiles and amphibian species have evolved to be clever, or nice but dim. We also discuss cannibalism by snakes, which is actually pretty common albeit difficult to document due to their secretive lifestyles. Become a Patreon:…
This week we delve into the evolutionary history of a fascinating little salamander from North America: the cascade torrent salamander. Volcanoes and flooding have shaped this species' history over the last 15 million years, but they remain steadfast. Then we chat about some newly described frogs from Ecuador.

This week we're diving into two reptile papers: the first is about desert lizards being secret nutritional strategists, timing what they eat across the year to nail mating season and prep for hibernation. Then we stumble into the chaotic world of rattlesnake seed dispersal, where a snake eats a rodent that ate a seed, and thanks to the snake, a tree grows. Become a Patreon:…
Bradykinin is a hormone that is released naturally in response to tissue damage, so if you hurt yourself, it makes it hurt. Quite a few animals from wildly different evolutionary histories have defensive toxins which are fake copies of this hormone. We discover which animals have them, when these defences evolved, and ultimately, how they are used for defence. For our Species of the Bi-Week there…
Invasive species are well known to damage ecosystems by directly eating other animals and disrupting the food chain. But their impacts can go much deeper, as a new study about seed dispersal by pythons and tegus in the Everglades has shown - they may be contributing to the destruction of rare and unusual habitats.

Pitvipers of the genus Bothrops are famed for their camouflage and for being deadly ambush predators. New insights from snake CCTV have revealed that these snakes can only really catch and eat animals who can't spot them hiding in the leaf litter, and it's bad news for our furry friends. Then we chat about a jazzy new species of newt described from central China. Become a Patreon:…
Mimic poison frogs are utterly amazing, famous for mimicking multiple different frog species, and like other dart frogs they demonstrate bi-parental care where both male and female frogs team up to look after the young. What we didn't know was how flexible these parental roles are - can females step in to move tadpoles when males start slacking, and what triggers them to do so? It turns out they…
Chinese conservationists have worked hard to protect the critically endangered Chinese alligator, creating new habitats for them after significant alterations made most of their Yangtze River home unsuitable. Thanks to the power of GPS technology, we now have some fascinating insights into how they are using the wetlands they are being reintroduced to, and it's mixed news. We follow that chat up…
Common knowledge suggests that albino animals are rare in the wild because they stick out like a sore thumb and get eaten by predators, but studies supporting this are relatively scarce. Now, researchers from Australia have discovered that the drawbacks of albinism are not limited to their obvious appearance. Even better, they used our old friends cane toads to prove it.

New methods in antivenom technology may yield a treatment that works on most of the cobras in Africa, thanks to the blood of alpacas and some very clever scientists. Then we follow up with two new species of sleepyhead snake from Venezuala.
