Three new live-bearing toads from Tanzania!
This week we have published an exciting new paper describing three new species of bumpy, bright-coloured, live-bearing, tree-dwelling toads from the Eastern Arc Mountains of Tanzania! You can read …

Three new species of tree toads from Tanzania have been discovered. 🐸

These amphibians don’t lay frogspawn or have a tadpole phase like most other toads, but instead give birth to live young!

Find out how museum specimens helped scientists to discover these species. 👇

Watch this space for some news at 12:00 GMT tomorrow! Something new for me, and a really awesome collaboration. 🐸🧪

Seems obvious to me that having a gut that be longer than your body is clearly advantageous. This is a great way to overcome one of the limits imposed by diminutive body size itself!
Crazy-looking larval cusk eel with an impressive external gut. We’re still not sure why having the intestines on the outside is advantageous, but there must be a good reason 🤔
TL ~2.5cm

It has been an extremely dry year for me in terms of publications so far, but a flurry of activity in the last few weeks has left me with eight papers submitted and two in press due to drop in the next couple of weeks! A total turnaround. Huge push by many coauthors. Next year may be a bumper! 🧪

My exit from the other site cost me a contact and wondering if anyone can assist with a taxonomist who works on polychaetes??? 🪱🧪🔬

Frog-people! What’s the current consensus on the origin of chytrid? Is shipping Xenopus around the world in the 1930s still the vibe or is an East Asian/Korean origin for the pandemic lineage where we’re at these days? 🐸

Violet webcap (Cortinarius violaceus) growing under gorse today near the Devil’s Punchbowl in Surrey. An absolute stunner of a mushroom and nationally rare - it’s always good to see these beauties.

After ELEVEN YEARS of work, today I finally submitted my 205-page monograph on the diamond frogs of Madagascar, genus Rhombophryne, in which we are describing several new species. Feels so good to finally have it submitted. I can't wait to share the new species with you all! 🧪🐸🟤💎

So sorry to hear of Dame Jane Goodall's passing. What a life to celebrate, though! One of my most prised possessions is my copy of the Silmarillion, which she signed for me in 2014 when she came to deliver a talk in Munich. She said that she, too, admired the works of Tolkien. 🧝‍♀️💎💎💎

Spent a little time in the last couple of day working with micro-CT scans of frogs again. This is the holotype of Rhombophryne coronata. I’m hoping to submit a manuscript including a plate of this specimen’s skeleton tomorrow! 🧪🐸🩻

@herphighlights.bsky.social heya, the call you played as Heterixalus boettgeri in Episode 235 is a microhylid, not a Heterixalus. It may be a Plethodontohyla or a Platypelis. Heterixalus have cricket-like stridulating calls.

Four generic frogs? No! These are members of four different FAMILIES from Europe, Borneo, Madagascar, and East Africa, convergently evolved on the generic brown frog morphotype! 🧪🐸

Check out the remarkable variation in the Critically Endangered Anodonthyla theoi. It is restricted to a tiny area of littoral forest in SE Madagascar, and its habitat is extremely threatened by deforestation and fire. When the rains come, males emerge from tree holes and leaf axils to call. 🐸🧪

Just another day at the office! Today, we needed to get a specimen out of the freezer to be prepped as a skeleton, so we pulled out this nice big Paleosuchus trigonatus. 🐊🧪

Look at the fantastic variety of shape in these wonderful frogs I photographed in Gunung Mulu National Park on Borneo last year. Amazing how much frogs can do with so little. 🐸🧪

Having a diffuse research group means that I rarely get to spend any time with my group in 3D. It was a great delight therefore to be joined by @collinbos.bsky.social @alicepetzold.bsky.social @njorisfleck.bsky.social and @clarakeusgen.bsky.social together in Bonn for the #SEH2025! 🧪🐸🦎🐍🧬
