Here’s a photo of one of my favourite anurans: the fantastic Helmeted water toad, or Gay’s frog* Caudiverbera caudiverbera, a large, robust Chilean species (the only extant member of its genus) that is said to mostly feed on other anurans (though it also eats insects and other arthopods, fishes and even small birds and mammals)…
Females can reach an SVL (that’s snout-to-vent-length) of 320 mm, which is huge. Its larvae reach a ridiculous size of about 150 mm and take about two years to metamorphose. Together with another obscure Chilean anuran (Telmatobufo), Caudiverbera has conventionally been included within the leptodactylids (a huge motley assortment of mostly South American anurans) but… well, I don’t want to say any more as that would spoil the surprise and, besides, this was meant to be nothing more than a picture of the day submission, and already I’ve written too much. Lots more on obscure anurans and other lissamphibians to come soon. It’s going to be timed to coincide with a very special event. Well, special-ish.
Much better photos of Caudiverbera are available elsewhere on the web, such as at Felipe E. Rabanal’s Anfibios de Chile.
* Not ‘Gray’s frog’ as it says in some books.
