|Latin name:||Lepus marinus|

The hare of the sea
The sea-hare appears in some medieval encyclopedias. Some medieval "naturalists" believed that for every land animal there should be an equivalent marine animal; this idea is as old as Pliny the Elder's Natural History.
There is a group of marine molluscs called sea-hares. They can be quite large, and have a rounded body with two long projections from their heads that resemble the ears of a hare. The animal has been known and described since Roman antiquity or earlier.
