Deep below the surface of the Indian Ocean, this patch of seabed teems with life.

Translucent eels, fanged fish, and other peculiar creatures wriggle between corals and rock formations off the coast of Australia’s Cocos (Keeling) Islands.

A recent deep-sea expedition just captured never-before-seen views of this part of the seafloor.

Earlier this month, a crew of scientists on board the research vessel Investigator returned to mainland Australia after 35 days of exploring the deep.

Researchers from several organizations, including the Museums Victoria Research Institute and CSIRO, departed from Darwin on September 31 and sailed to the far-flung islands.

They probed up to 5500 meters (18,044 feet) below sea level, collecting data on undersea volcanoes and surveying the species that live there.

The researchers also brought back numerous deep sea specimens — some of them creepier-looking than others.

Here are 10 peculiar deep sea creatures recovered from the expedition:

10. The deep-sea Viperfish sports glassy icicle teeth and a marbled eye with a shimmering blue ring around it.

9. Eerie, transparent skin covers the body of a blind eel that was previously unknown to science.

7. The Highfin Lizardfish has a similarly menacing set of teeth designed to snatch prey as it swims by.

6. It’s not a full Great White Shark, but the researchers did snag one of its lost teeth from the seafloor.

5. The tiny Tribute Spiderfish uses its long appendages to stilt-walk across the seafloor.

4. Which way is this flatfish looking?

Its asymmetrical face makes it hard to tell.

3. This is the flexy Synaphobranchyus eel, wrapped in a neat spiral.

2. Though known as a cusk-eel, Lamprogrammus is actually a genus of fish that look surprisingly eel-like.

1. Shaped like a dumpling, Batfishes like this one shimmy across the deep seafloor with their fins.
