A tangle of aquatic caecilians, including gravid females.
It was about midnight and a heavy seasonal shower had just abated. I was standing on the edge of a small inlet on the Rio Orosa in Amazonian Peru. I had been hoping to find a small aquatic snake or two, had actually succeeded (another story), and was just about to call it a night when a bit of a commotion in the shallows a dozen feet from me caught my eye. I hurried the few steps needed to get to the disturbance, and saw what appeared to be a big dark colored worm rapidly coiling and uncoiling.

Dark and a worm, eh? Ah ha! An aquatic caecilian, Typhlonectes compressicauda, my first in the wild. .As I watched it uncoiled and moved slowly—forward, stop, reverse a little, probe, forward again--into some water edge, emergent, vegetation. I watched it for another 5 minutes before it disappeared into the bottom mulm.

These representatives of the third group of amphibians (the other 2 being the caudatans and the anurans) were once common (although, legally they shouldn’t have been) in the pet trade. Most that arrived here (USA) were imported from Colombia as tropical fish (“rubber eels”, if you will—they were also marketed as “Sicilian” eels!). Adults are hardy aquarium animals, feeding well on black (tubifex) worms or sectioned earthworms. Adults are legless, finless, have a tactile tentacle, and lack external gills. The babies, borne alive, have large, external, parchment like gills.

Perhaps at some point in time these will again be available; perhaps not. But if they are, they are an interesting and easily kept amphibian species for aquarists and herpers alike.
