Typhlonectes natans
A fully aquatic caecilian from the rivers of Colombia and Venezuela. Limbless and dark grey to black, it reaches 55 cm and carries out most of its respiration through the skin. It is ovoviviparous and gives birth in water.
Typhlonectes natans is a fully aquatic typhlonectid caecilian from Colombia and Venezuela. It reaches 45-55 cm and is dark grey to black, with a limbless worm-like body marked by ring-shaped grooves and extremely small eyes. It does occasionally breathe air at the surface, but most of its respiration is cutaneous. It occupies a wide range of waters, from dry savanna and tropical shrubland to seasonally flooded lowland grassland and rivers. It is ovoviviparous: after a gestation of about 220 days, three to seven fully developed young are born in the water, reaching about 25 cm, close to half adult size, within a year. Aquarium shops sometimes sell it as a fish under the name rubber eel, but it is an amphibian of the order Gymnophiona. In October 2019 a specimen was collected in Miami-Dade County, Florida, the first caecilian recorded in North America, and further animals with evidence of breeding suggest it may be establishing there.

Earthworms, shrimp, small fish and other small animals
It lives in tropical rivers and seasonally flooded lowlands. Hold the water steadily at tropical levels matching its range and avoid sudden swings.
Being fully aquatic it needs a tank whose volume and floor area suit a 55 cm animal. Most of its respiration is cutaneous, so water quality matters more than usual. Add pipe sections or driftwood as hides, and leave access to the surface for occasional air breathing.
Caecilians are generalist carnivores; stomach contents of wild animals include earthworms, termites, shrimp and small fish. Feed animal-based foods in captivity as well.
Its eyes barely function and it locates food by smell and by its chemosensory tentacles. It is slow and not aggressive, but fish small enough to swallow are potential prey.
It is sometimes sold as a fish under the name rubber eel, but it is an amphibian, so fish medications and high aquarium temperatures do not suit it. A population apparently derived from released animals is establishing in Florida, so never release it outdoors.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Rio Cauca Caecilian is 5-10 years. With proper care and nutrition, they can live a long and healthy life.
