Everybody loves glassfrogs

Glassfrogs (or centrolenids) are a really interesting but comparatively little known group of anurans, you might have heard of them. Ha ha, just kidding – you know them well already since they were recently covered at reasonable length here at Tet Zoo. Since that article went live, I’ve been talking with glassfrog expert Juan Manuel [...]

Glassfrogs: translucent skin, green bones, arm spines

Glassfrogs, or centrolenids, are wide-skulled, long-limbed arboreal little frogs (SVL 20-60 mm), unique to the Central and South American cloud and rain forests. Not until 1951 did this group get recognised as a distinct and nameable entity: prior to this, species within the group (known to science since 1872) had been classified as part of [...]

The New Forest Reptile Centre

Back in May this year I visited the New Forest Reptile Centre (Holidays Hill, near Lyndhurst, New Forest National Park, Hampshire, UK). I’ve been meaning to visit for a long time – I think I last went there some time during the late 1990s – and the very hot and sunny weather meant that it [...]

Dwarf mountain toads and the ones with the doughnut-headed tadpoles

As you’ll know if you’ve been following Tet Zoo for any length of time, I’ve been slowly working my way through the toads of the world for the past few years – yes, all of them, more or less. Seeing as there are about 540 living toad species, this may take a while. I’m currently [...]

20-chromosome toads

More toads! (for previous articles in the series – required reading if you’re really interested – see the links below). In the previous article I introduced the idea that a large number of (mostly) poorly known African toads might be close relatives: they generally group together in cladograms, and – even when they don’t – they [...]

The toads series comes to SciAm: because Africa has toads too

One of my long-term goals at Tet Zoo has been to complete my series of articles on the toads of the world… actually, this started out as a short-term goal, but it ended up taking rather longer than expected. This enormous, near-globally distributed anuran clade (properly termed Bufonidae) encompasses incredible variation and a huge amount [...]

In pursuit of Romanian frogs (part III: brown frogs)

Time to look at more of the frogs I encountered in Romania. In the previous article I discussed Western Palaearctic water frogs (the species of Pelophylax). Here in Europe, water frogs live alongside another group of ranid frogs – the brown frogs, the only frogs unambiguously and unquestionably associated with the generic name Rana. Well, [...]

In pursuit of Romanian frogs (part II: WESTERN PALAEARCTIC WATER FROGS!!)

As you’ll recall if you read my recent article on Yellow-bellied toads Bombina variegata you’ll know that I recently wandered about the Romanian countryside, hunting for frogs. You can never have too many frogs and, these days – what with the global amphibian crisis and all – you typically don’t. The good news is that [...]

In pursuit of Romanian frogs (part I: Bombina)

I recently spent a bit of time in Romania, working with colleagues in an effort to find new Cretaceous reptile fossils. As usual, I can’t talk about what we found (yet. And we did find a lot). But what I can talk about is the modern-day wildlife I encountered while on the trip. Partly due [...]
