Chthonerpeton haydee Roze, 1963 Typhlonectes natans, also incorrectly called the rubber eel, is a species of caecilian in the family Typhlonectidae found in Colombia, Venezuela, and possibly Trinidad and Tobago.

A specimen of T. natans was found in October 2019 in Miami-Dade County, Florida, making it the first caecilian to be collected in North America.

While T. natans can and occasionally does breathe air at the surface, most of its respiration takes place through its skin.

The species is ovoviviparous, giving birth to young in water.

Three to seven live, fully developed young are born, which after only one year reach almost half the size of an adult (25 centimetres (10 in)).
