May 05, 2021 11:17 AM EDT Many parts of the ocean are still unexplored, including a wide variety of strange underwater life that scientists have barely begun to understand. In fact, some of these can be so bizarre that common names for them are elusive. Such is the case of Ramisyllis multicaudata, a very peculiar sea worm with various segments that each has its own set of rear ends. Though as silly as that sounds, it may not appear that way to the common eye. In fact, the most amazing thing is that they do not appear to be worms at all, but look more like white filigree coming out of many of north Australia's resident ocean sponges. (Of course, similar species have been found near the Philippines.)
