In our world, the Xenarthan lineage of mammals is... Well, confined to the land, with only one lineage experimenting with sea-travel, the Thalassocnus. However, as shown here, in this alternate earth, many, many, pelagic members of the group have survived until the present day, with all but one still having populations of least concern to this year. Pictured here are the Seaanteater, a massive relative of the giant Antteater, the Sea sloth Mareoccisor rex AKA the Sea Bear, a descendant of Thalassocnus that has become a highly evolved carnivore and another Sea Sloth commonly known as the Sea Swine, with a massive Doedicrius like Sea Glyptodont having evolved to conquer the water as well. These Xenarthran swimmers all have one thing in common: That is to say, not a lot. All but two of these strange ocean going mammals are related, with the Seaanteater having entered the water 1 million years and the Sea-Glyptodont entering 2 million years ago. To be specific, all five of these distantly related animals descended from long extinct stock and diverged significantly. And, they can not walk on land, much like cetaceans and all members of the Sirenidae order which contains Dugongs and Manatees. In fact, most are still relatively unspecialised, all having large claws and four legs. Out of the five Xenarthrans shown, Mareoccisor is the most specialised. This picture depicts the varying lifestyles of these various Xenarthrans as they go about their business... With a lone bull Sea Bear as the main focus.
