Nudibranch With a Shrimp Partner

Wallpaper Description:

Amidst the bright blue tufts and the dark blue fringes of the beautiful Risbecia tryoni, you might not even notice the red emperor shrimp (Periclimenes imperator). The two animals are native to the Indo-Pacific region and are often found accompanying each other. The nudibranch eats sponges, while its shrimp partner feeds on worms. Both are small creatures, with the nudibranch typically reaching 60 millimeters in length.
