by Christopher Mayerl, Evolutionary Morphology and Biomechanics Laboratory at Clemson University (S. Carolina, USA). If you would like to contribute a guest post, please get in touch, such as on Twitter or Facebook. When you see a turtle, you automatically know it’s a turtle and not something else, probably because of its distinctive shell. However, there’s…

In focus: The big picture of little bones in tuatara

By Sophie Regnault with John Hutchinson and Marc Jones Sesamoid bones are specialised, typically small, bones found in tendons near to joints, with several unusual characteristics. We’ve covered them here before. These sesamoids tend to alter the mechanics of joints, and their development also seems highly influenced by movement. They can vary between individuals or…

In focus: What is the Portuguese Man-O’-War?

Our guest post this week comes from Emei Ma, a scientific artist. If you would like to contribute a guest post, please get in touch on Twitter or Facebook. Occasionally, we come across an image or a video that compels us to ask, “What is that?” Such was the case when I saw the mesmerizing work of Aaron…

In focus: The mysterious extra ‘digits’ of pandas, moles and elephants

The biological ‘five finger rule’ is strikingly consistent throughout living tetrapod vertebrates. Humans and other primates, most carnivorous mammals, crocodiles, lizards and tortoises all typically possess the five digits (fingers and toes) characteristic of tetrapod limbs. It wasn’t always so – the ancient ancestors of the first vertebrates to walk on land, such as Ichthyostega and Acanthostega, had up to…

#FossilFriday: Ingenious camouflage found in ancient amber-preserved insects

While many species are known to have evolved specialised colouration to better blend into their environmental backgrounds, there is another important form of camouflage: incorporate your environment into your appearance! This can be seen across the animal kingdom, including in insects and their larvae, sea urchins, and snails. Now, researchers have found some of the…

Sloths’ mysterious teeth decoded

Like most mammals, we humans have a variety of tooth types for different purposes: incisors, for gripping, canines for ripping and tearing, and molars (also pre-molars) for grinding and chewing. But one group, known as the Xenarthra (a particularly excellent name meaning “strange joints”), have very simple dentition, with similar, unrooted teeth which lack enamel and…

Incredible electron microscope GIF gives an amazing sense of scale!

//giphy.com/embed/26BRQY7cHMMVzU6n6 This series of SEM (scanning electron microscope) images shows a tiny crustacean called an amphipod before zooming in on a miniscule diatom resting on its head, and finally picking out the shape of a single bacterium on the surface of the diatom. A truly awesome science GIF! Via Smithsonian mag, GIPHY.

In focus: Launching our new CrocBase project!

We are delighted to announce the launch of the first of several new open access databases from John Hutchinson’s team at the RVC, containing complete CT and MRI scans of almost all our modern crocodile specimens! Our CrocBase is hosted via the Open Science Framework, and contains 53 scan datasets of five crocodilian (AKA crocodylian to scientists) species…
