Contrary to popular belief, the slow loris is not actually a venomous primate. Rather, the animal produces an allergen (Fel d1) from a gland in its armpit, which is transferred to the mouth when licked. When the loris then bites, this chemical doesn’t elicit a response because of toxicity; some individuals just have a strong allergic reaction. Quite astoundingly, this allergen is the same as that produced by the domestic cat. So in effect, if a slow loris is venomous, then so is the common house cat!

On a side note, can you see the small second tongue? It’s called a sublingua, and most likely functions to remove hair and debris from between the teeth - it’s basically a built in tooth pick!

Reptile? No. Fish? No. Earthworm? No. Amphibian? Yes! This animal is a caecilian - in fact, the individual pictured here belongs to a recently discovered species!

Although this image just looks like a rock formation, pictured here is actually a species of chiton, Acanthopleura granulata. Recent research on this animal identified functional eye-like structures on each of the shell plates. Rather than being formed from proteins, these “eyes” are actually composed of aragonite, a carbonate mineral. Interestingly, the team of researchers concluded that aragonite can be used to form a lens effective both above and below water.

Everyone knows what a moth and a butterfly is, don’t they? The differences between the two are obvious, right? Wait … what do you mean it’s not a straightforward answer, like we’ve come to expect from the world of ecology? Okay then, so just what is the difference between a moth and a butterfly? Phil travels to the Lower Derwent Valley National Nature Reserve to answer the question once and for all. Hopefully…
