The Hipp, a.k.a. Sea-Horse of Ganymede (Hippocampus Catamiti), is an amphibious creature native to Ganymede which can be used as a mount by Human colonists.
Hipps have a 20-foot-long body with only two feet and a tail, and also possess a hard outer shell which protects them from Gamma Rorqual attacks.
