They can grow up to about four inches long, says National Geographic. They have mutualistic relationships with anemones, but are able to avoid their dangerous stings because of a special mucus they secrete. Out of the 30 species of clownfish, the two most widely known are the orange clownfish ( Amphiprion percula) and the ocellaris clownfish ( Amphiprion ocellaris). Though many people are scared of clowns, this tiny fish is anything but scary.

Goblin sharks can also protrude their snouts to reach out and grab prey, which is covered in electroreceptors to detect prey in dark waters. With a flabby body, elongated and flattened snout, and gray-pink coloration, this deep-dwelling shark is incredibly unique looking.

TheyвЂ™re capable of scurrying up to 10 miles per hour, able to quickly disappear from predators into burrows that can extend for four feet underground. Ghost crabs are aptly named for their abilities to camouflage with the sandy beaches and dunes that they inhabit.

Horned puffins hatch from their eggs with small, black вЂњ horn marksвЂќ above their eyes already visible, making them easily distinguishable from other puffin species. The horned puffin-the least common of the puffin species-is found along the North American West Coast.

This elusive species escapes predators by flashing photophores outlining its arms and fins, and ejects a bioluminescent mucus into the water before vanishing in a flash. The vampire squid is the only squid species that spends its entire life in dark, oxygen-poor deep ocean waters. Take a look below to learn more about some ocean animals that are aptly prepared for the holiday this week.ДЄn illustration of a vampire squid ( Vampyroteuthis infernalis).

With Halloween just around the corner, weвЂ™re taking a close look at marine animals that are able to celebrate Halloween all year long through their fear-invoking names. With some species, though, the fright isnвЂ™t in their looks but simply in their name-like the vampire squid or ghost shrimp. As you probably know, the vast, deep ocean is home to rich amounts of biodiversity-much of which appears rather spooky and frightful, like anglerfish with their many sharp teeth, to the stargazer fish with eyes on top of their head.
