1) Blobfish (Psychrolutes Marcidus)

Blob Fish Small


The Blobfish is a deep sea fish that can be found off the coasts of mainland Australia and Tasmania.

It’s tricky to catch sight of a blobfish owing to the depths at which it lives.

The fish is made up of a gelatinous mass with a density only slightly less than water.

It’s lack of muscle does not prove problematic  as it feeds on edible matter that floats across it’s path.

2) Orange Sea Pen (Ptilosarcus Gurneyi)

Sea Pen


Sea Pens can be found in tropical and temperate waters worldwide.

Named of their  feather-like appearance reminiscent of antique quill pens, not all species live up to the comparison.

Using their root-like peduncles to anchor themselves in sandy or muddy substrate, the exposed portion of sea pens may rise up to two meters.

Rarely found above depths of 10 meters, sea pens prefer deeper waters where currents are less likely to uproot them.

3) Narwhal (Monodon Monoceros)


The Narwhal is a medium-sized toothed whale that lives year-round in the Arctic, found primarily in the Canadian Arctic and Greenland.

The Narwhal males are distinguished by their long, straight tusk extending from their upper left jaw.

It feeds on mostly flatfish, at depths of up to 1500 meters under dense pack ice.

Narwhal have been harvested for over a thousand years by the Inuits for meat and ivory subsistence hunts continue to this day.

4) Seawolf (Anarhichas Lupus)

Sea Wolf


The Seawolf or Atlantic wolffish is a marine fish, the largest of the wolffish family – Anarhichadidae.

The numbers of Seawolves are rapidly diminishing due to overfishing and by-catch.

Although it is a gruesome looking creature, the Seawolf is only a threat when defending itself outside of the water.

Seawolves can also be distinguished by the natural antifreeze they produce to keep their blood moving  in their very cold habitat.

5) Yeti Crab (Kiwa Hirsute)

Yeti Crab


The Yeti Crab or Yeti Lobster is a crustacean discovered in 2005 in the South Pacific Ocean.

Approximately 15cm long, the yeti crab is notable for its silky blond fur covering its legs and claws.

The crab also has strongly reduced eyes that lack pigment, and is thought to be blind.

6) Flying Gurnard (Dactylopterus volitans)

Flying Gurnard


The Flying Gurnard is a fish of tropical to warm temperate waters on both sides of the Atlantic, found as far north as New Jersey and as far south as Brazil.

When calm, the fish looks fairly normal. When excited, the fish spreads its “wings“, which are semi-transparent with a bright blue phosphorescent color (designed to scare away predators).

The fish also has large eyes and the head is similar to species of porcupine pufferfish.
