Frog-killing fungus is a skin-loving hybrid

Frog-killing fungus is a skin-loving hybrid

These are not the best of times for amphibians. All around the world, populations of frogs, salamanders and newts are declining. At least 489 species (7.8% of all known amphibians) are nearing extinction.

The Biology of Sirens

Sirens build nests, have beaks, eat plants and have a history of "size shuffling"--they're incredible!

Nobody Expects the Korean Crevice Salamander

The presence in Europe of plethodontids is unusual enough (albeit well known), but a major surprise in plethodontid research was the discovery of an Asian member of the group, the Korean crevice salamander Karsenia koreana Min et al., 2005. Plethodontid expert David Wake described its finding as “the most stunning discovery in the field of herpetology during my lifetime”...

<i>Megophrys</i>: so much more than <i>Megophrys nasuta</i>

Megophrys: so much more than Megophrys nasuta

In the previous article, we looked at parsley frogs or pelodytids - a small and conservative lineage within the anuran clade Pelobatoidea (also known as Anomocoela, and commonly as the spadefoot toads).

Tadpole nests, past and present

Thanks to that recent Tet Zoo article about American spadefoot toads and their tadpoles, I've had visions in my mind of drying ephemeral pools in hot, arid environments, crammed with crowded, gasping tadpoles.

Sunday Species Snapshot: Panamanian Golden Frog

Sunday Species Snapshot: Panamanian Golden Frog

These tiny, brightly colored amphibians pack a potent neurotoxin on their skin. That toxin protected them from predators, but it won’t save them from extinction.

Teenage Mutant Ninja Temnospondyls

You all enjoyed the many Platyhystrix images featured here the other day (interesting discussion still going on in the comments section on that article, check it out).

Because caecilians are important

Because caecilians are important

This is the 200th article at Tet Zoo ver 3 – thanks, pass the champagne, donation cheque etc. (hint hint). The plan is to produce a lengthy introspective-type article that includes links to all the content that’s appeared on Tet Zoo ver 3 so far.

Model salamanders, in a cave

While on a family holiday recently I visited Dan yr Ogof, the famous National Show Cave for Wales. Besides being interesting for the expected geological and speleological reasons, Dan yr Ogof is set within landscaped gardens that, bizarrely, feature one of Europe's largest `dinosaur parks'.

33% of the newts of my country

33% of the newts of my country

I know the newts of my country… but that’s not hard, there are only three (or four if you count the alien one). The Palmate newt Lissotriton helveticus is Britain’s smallest species (reaching 95 mm in total length), though it’s not the smallest of all European newts, being exceeded by the 80 mm Italian newt L.

A Need for News on Nototriton

I must have said that one of my aims here at Tet Zoo is to write about obscure amphibian species that rarely get covered elsewhere. The main thing stopping or slowing this plan concerns the availability of images – good, available pictures showing the species concerned are often not availability. Anyway, through the good graces of Jonathan Kolby, I here present an image of the extremely rare tropical American plethodontid salamander Nototriton brodiei of Guatemala and Honduras. The animal is known from less than ten specimens.

Parsley frogs: spadefoots without spades

Parsley frogs: spadefoots without spades

Anurans - frogs and toads - haven't received enough coverage on Tet Zoo of late, so here's one of several efforts to redress the balance. For no particular reason, in this article I want to talk about pelobatoids, also known as anomocoelans: the anuran group that (as conventionally conceived) includes spadefoot toads (Pelobatidae) and parsley [...]

THE AMAZING WORLD OF SALAMANDERS

THE AMAZING WORLD OF SALAMANDERS

Tet Zoo loves amphibians* (that’s anurans, salamanders, caecilians and their close relatives), and since 2008 I’ve been making a concerted effort to get through all the amphibian groups of the world.
