Microbrachis was an elongated,
salamander-like creature, about long, with over 40
vertebrae instead of the average 15–26 in its living relatives. It had minute limbs, and probably swam using
fish-like lateral body movements.
Microbrachis probably fed on fresh water
plankton such as
shrimp.
Microbrachis was
pedomorphic, retaining its
larval
gills in adulthood. Similar traits are found in the extant
axolotl. == References ==
