Last week I gave you this long, pink, wrinkly specimen to have a go at identifying:

There was a lot of discussion about whether it has limby bits, fins, flaps left over from damage during preparation or some other unnamed and dubious appendages. I’m relieved to confirm that it has limbs – albeit rather reduced limbs.

The limbs are important, since they allow us to rule out all the legless groups of similar critters, like Caecilians (limbless amphibians), Synbranchidae (swamp eels), Amphisaenidae (worm lizards) or of course snakes (not that any self-respecting snake would have a face that looks like it belongs to a poorly made sock-puppet).

The state of the legs, especially the very reduced state of the front limbs, also allows us to rule out a variety of Olms, Sirens and other Salamanders – except for one odd little genus called Amphiuma.

There are only three living species of Amphiuma – the One-toed, Two-toed and (believe it or not) Three-toed. Someone in the past hedged their bets and labelled the mystery specimen as follows:

Since the Three-toed salamander is Amphiuma tridactylus Cuvier, 1827 and the Two-toed is Amphiuma means Garden, 1821 this label is misleading.

The Three-toed salamander does have three visible toes on the forelimb and this specimen clearly doesn’t – with just a vestigial wriggly bit (that doesn’t make it the One-toed salamander however, as they are smaller and they have an even more reduced hind limb). So this is the Two-toed Amphiuma means.

Finally, it might be a bit confusing that the mystery object is a pink thing, while the living animal is a mottled muddy colour. That’s just an artefact of it being preserved in ethanol for the last 125 years. Trust me, no-one looks good after that much exposure to alcohol.
