Microbrachis ('small arm') is an extinct genus of lepospondyl amphibian from the Carboniferous period. It was about 15 cm (6 in) long.
Microbrachis was an elongated, salamander-like creature with over 40 vertebrae instead of the average 15-26 in its relatives. It probably swam using fish-like lateral body movements, not using its small limbs. Microbrachis probably fed on fresh water plankton such as shrimps. Microbrachis was pedomorphic, retaining its larval gills in adulthood. Similar traits are found in the extant axolotl.
