Mesmerizing Footage Of Undiscovered Deep-Sea Life

Our oceans cover more than 70% of Earth’s surface. While the ocean remains largely unexplored, we occasionally get a glimpse of the weird and wonderful creatures that eke out a living in the deep. There are countless creatures on this planet we'll likely never discover. There are many creatures, some cute, some terrifying, and most of us know little about them.

Pink Dorid Nudibranchs: Nudibranchs are an order of marine gastropod consisting of more than 3,000 species. They are soft-bodied, slug-like animals many of which are adorned with bright colors and extravagant body forms. Most nudibranch species live on reefs in temperate and tropical seas and are a popular species to observe by SCUBA divers around the world. There are so many species of nudibranch, their forms are very diverse. The smallest species is just 0.16 in (4 mm) long while the largest species can grow up to 23 in (60 cm) long. They all have small, simple eyes set into their bodies that are able to do little more than discern various levels of light. These slugs can be found in oceans around the world, even in the Arctic and Antarctic. The largest diversity of nudibranchs occurs in warm waters on shallow reefs, although a recently discovered species was found at more than 8 200 ft (2 500 m).
