Minecraft Update Aquatic Hostile Mob LEAKED

So the Update Aquatic is a needed update for Minecraft as a whole. Oceans are quite boring and need some new content. And we are getting it in 1.13. However, it was announced that we would be getting a new hostile mob for the ocean.

From the image above, it shows what looks like a water zombie. Jason Major tweeted this image out. We don't have much info but I think it will spawn around shipwrecks to protect them. The texture looks quite different as well compared to other mobs for the ocean.
