The Beautiful Imperial Nudibranch.

This two-inch-long sea slug has some amazing colors, and was almost extinct a few years ago. In the 1970s divers would find these slow-moving creatures out on the reef on a regular basis, but by the 1980s they all disappeared. It wasn’t until recent times that they started showing up again, and when I saw two of them on a dive in Maui a few days ago I was extremely happy to know that this stunning nudibranch still exists in Hawaiian waters.
