15 Super rare creatures of the sea

by DrPrem Jagyasi

With every dive into the ocean, explorers are finding rare species thriving in the deep seas. For a long time, it was believed that no life form could thrive beyond depths of 1800m in the deep sea, where even light fails to reach. We have only explored 5% of the total ocean cover of the planet, which is why with each deep sea dive, newer species are surfacing. These strange looking alien-like creatures appear to have arrived from a different world. Here are the 15 rarest creatures of the sea.

First discovered in 1985 in the waters of eastern Australia, more than a hundred goblin sharks were reported in the north-eastern waters of Taiwan after an earthquake. This slow-moving, deep sea creature is still a mystery to scientists. It has a unique set of dentition to serve dual purposes and can grow up to 3.8 meters or more.

Living at depths of 600-900m, this squid is a relatively low-level dweller when considering squids. It has large eyes in terms of its body size proportions and has a unique defense mechanism. The squid releases a bioluminescent ink to confuse the other animals and escape.

This mysterious shark belongs to a group of primitive sharks known as chimeras, which reportedly branched away from sharks about 400 million years ago. Using fins to ‘fly’ through water, this shark has been sighted deep of the coast of California. The male has a spiky, club-like, retractable sexual organ that protrudes from its forehead.

Water bears (or tardigrades) are tiny invertebrates that live in aquatic and semi-aquatic habitats such as lichen and damp moss. Paramacrobiotus craterlaki is a carnivorous species that feeds on nematodes and rotifers. Water bears are found throughout the world, including regions of extreme temperature, such as hot springs, and extreme pressure, such as deep underwater. They can also survive the high levels of radiation and vacuum of space. Magnification: x330 when printed at 10 centimetres wide.

The world’s toughest known creatures are a micro-species known as water bears. These are classified as extremophiles, meaning they can thrive in conditions that are completely unfavorable for all life on Earth. They are reported to have lives spanning more than 200 years.
