The Rarest Marine Animals In The World

The ocean is a vast and mysterious place, full of beauty and questions. It captures our imaginations. It makes us think about freedom and solitude. The ocean also makes us think about the myriad, disparate creatures that fashion their existences beneath those constantly moving blue waves. There truly is another world under the surface and it is full of wonderment. From hermit crabs in the tidal pools of Maine to the coral reefs off Australia’s coast to the largely unknown creatures of the Mariana Trench, the life that exists in the world’s oceans is awesome and most certainly worth investigating .

The ocean covers up to 70 percent of the Earth, making it the largest ecosystem in the world. Deep below the surface lives millions of different marine animals, some breeds that have yet to even be discovered. Rare animals in the ocean are, obviously, hard to come by, but often come along with the most interesting characteristics.

What Is the Rarest Sea Creature in the World?

There are many shy sea animals, reticent and distant, that people rarely lay their eyes on. Perhaps the rarest is the Dumbo Octopus. These tiny creatures live in the extreme ocean depths of between 3,000 and 5,000 meters and they only grow to about 20 centimeters tall. These tiny members of the octopus family have big ears, which they use to swim and which is why they are named after that famous cartoon elephant.

What Are the Most Beautiful Sea Creatures in the World?

The oceans are full of beautiful creatures. Most of us think about the pretty little fishes that swim around coral reefs in the tropics, brightly colored and with stunning patterns. In truth, though beauty is in the eye of the beholder, we think that there is a lot of beauty in the sea.

Nudibranches are tiny mollusks that do not have shelves and their predilection to self-preservation is the source of their beauty. Because they lack shells, they protect themselves by employing camouflage to disappear into the seascape. Consequently, they boast bright, beautiful colors and patterns. Nudibranches live all over the world, from tropical waters to the frigid northern oceans.

The brittle star is a creature that mostly comes out at night, choosing to hide in crevasses during the day. Symmetry is a calling card of these animals, which have long, slender arms extending from a small circular body. One of the most captivating things about brittle stars is the way in which they move. They use their arms to pull themselves and move in a hypnotic, snakelike manner.

Leafy seadragons are found along the southern Australian coast. Arguably the kings of camouflage, they tend to float among kelp and seaweed, which look very much like the stringy, leaflike body of the leafy seadragon. These translucent wonders can change shades depending on the background and propel themselves through the water with thin, almost transparent fins.

What Is the Most Endangered Sea Creature in the Ocean in 2022?

Sadly, there are quite a few sea creatures that are currently on the endangered list. The vaquita, or little cow, is a species of porpoise and is perhaps the most endangered ocean creature on the planet. They live in the Gulf of California and there are less than 30 of them left on the planet. Though they are difficult to get a glimpse of, they prefer relatively shallow waters, relatively close to shore. Vaquitas generally can be found in waters less than 30 meters deep and not farther than 25 kilometers from shore. The biggest risk facing vaquitas are fishing nets, chlorinated pesticides and illegal fishing.

Rarest Marine Life Animals

  • Sea Dragon. The sea dragon is a rare ocean animal most easily identified by its leaf-like fins. The sea dragon uses these fins to blend into its surroundings to escape enemies. In addition, they are known to be symbols of luck in Australia, so they are usually hunted for festivals, which is a big reason their population is at risk of extinction.
  • Dumbo Octopus. Along with being one of the most interesting looking, the dumbo octopus is thought to be the rarest marine animal of all. It is called “Dumbo” since its fins resemble the ears of the Disney character. It is able to withstand high pressure and preys upon animals by swallowing them whole.
  • Spade-Toothed Whale. Unlike any of the whales we see, the spade-toothed whale is one of the rarest mammals in the world. The breed was discovered washed up on the shore of a beach in New Zealand. They are easily identified by their extremely long beaks, which helps them to dive up to 800 meters below the surface to feed on animals, such as squid. 
  • Blob Fish. The rare ocean animal, the blob fish, is extremely gelatinous to the point that it literally looks like a blob with a face. They live in the deep waters of Australia, Tasmania and New Zealand. In 2013, it was voted the ugliest animal in the world.
  • Marine Pig. The marine pig got its name due to its head and mouth looking strangely similar to that of a pig. These creatures live at the bottom of the ocean and feed on organic particles from plants and animals.
  • Hairy Toadfish. The hairy toadfish has a fascinating appearance, much like other rare marine animals. It is bright orange, so it lives among the corals and sponges so that it can blend in as much as it can to avoid enemies. Its round facial features and the fact that it jumps on its prey is what gives this rare sea animal its name. In addition, it possesses poison, which makes it highly dangerous.

There are so many marine animals that human beings have yet to discover. It’s rare sea creatures like the ones listed above that make it essential to protect our oceans so we can learn even more about our world! Spreading awareness on how to keep our oceans safe is the best way to take the first step in keeping them alive.
