Dermophis mexicanus - Mexican Burrowing Caecilian; a robust 'living salami' of a caecilian at St Louis Zoo
Jealous face being pulled at that one! Typhlonectes natans and T. compressicauda comprise my entire caecilian life list. While we're on amphibians, I'm very much liking the Anderson's Salamanders in the aquarium at Chester now (Ambystoma andersoni).
