Protosiren (SciiFii)

The sealatee (Protosiren modernus) is a species of large amphibious mammal of the order Sirenia that originally lived throughout the Lutetian and Bartonian stages of the Middle Eocene as an extinct species of Protosiren and was once extinct, but has since been brought back from extinction and introduced to the coastlines from all over the world (except the Arctic or Antarctica) to help boost biodiversity. Like most sirenians (manatee and dugong), sealatees feed on various aquatic plants including sea grasses as well as freshwater plants. Unlike manatees or dugongs, however, sealatees have hind limbs, which are well developed, although they are small and the sacroiliac joint is weak. Consequently, it is mostly aquatic, only coming onto land to rest and/or breed. The conservation status of the sealatee is Least Concern due to successful conservation efforts, the sealatee's wide range, and its ability to tolerate pollution as well as adapting to man-made beaches and seal docks.
