The frilled shark is a “living fossil” — a species that has retained some of the features of its primitive ancestors.
With its grisly appearance, the frilled shark is an example of a “living fossil,” an extant animal whose appearance has not evolved much through the millennia. The term can also apply to creatures that have few or no close surviving relatives.
What’s most unusual about this prehistoric-looking predator, which is endemic to the Atlantic and Pacific Oceans, is the way it reproduces. In other mammal species, embryos are nourished via a placenta. However, frilled shark embryos obtain energy from yolk sacs and mothers only give birth once their offspring are capable of surviving on their own.
Growing upto 7 feet long, frilled sharks primarily prey on squid. They’ve also been known to feed on fish — and even other sharks.
Hagfish are known for their repulsive feeding habits: Lacking jaws, they consume the decaying carcasses of other sea creatures by burrowing into them with tooth-like structures.
There are estimated to be 76 species of hagfish — and some live as deep as 5,500 feet below the water’s surface. They are also known as slime eels because of the goop their bodies produce to ward off predators.
Scientists estimate that there are 76 species of hagfish, which can grow to be between 16 and 40 inches long. Some live as deep as 5,600 feet below the water’s surface.
The Atlantic wolffish is a predatory species characterized by a mouth full of sharp, canine-like teeth.
A predatory species that feeds on hard-bodied or spiny invertebrates like sea urchins and large marine snails, this creature is not aggressive towards humans unless provoked.
You’ll find the Atlantic wolffish, which can grow up to five feet long, in the North Atlantic and Arctic Oceans. Preferring chillier water, it lives at depths ranging from 328 feet to 1,640 feet.
With its lengthy, eel-like body, this fish is also known as a wolf eel. Keep reading to know more about deep sea fishes in https://cedointercultural.org/‘s article.
The goblin shark has 50 teeth in its mouth.
You can identify goblin sharks — a rare, bottom-dwelling species — by the shape of their snouts, which are elongated and flattened.
With 50 teeth in their mouths, these gruesome creatures command attention.
Interestingly, female goblin sharks are larger in adulthood than the males of the species. Females can be a maximum of 11 inches long, while males grow to be an average length of 8.66 inches.
The Japanese spider crab can weigh up to 44 pounds.
Native to the Pacific Ocean, the Japanese spider crab grows up to 15 inches wide and weighs up to 44 pounds. It’s one of the largest known arthropods, a group of invertebrate animals that also includes lobsters, spiders, and insects.
The vampire squid’s scientific name, Vampyroteuthis infernalis, means “vampire squid from hell.”
In Latin, the name of this cephalopod — which is neither a squid nor an octopus — is even more sinister. Its scientific name, Vampyroteuthis infernalis, means “vampire squid from hell.”
But the vampire squid, found in the inky depths of the mesopelagic zone (about 3,300 feet below the ocean’s surface), is gentler than its appellation indicates. Unlike its namesake, it doesn’t feed on blood. Instead, this creature subsists on “marine snow,” decaying organic material that falls to the ocean floor — kind of like the dead leaves that litter forests.
The anglerfish is most famous for the bioluminescent growth on its head, which lures prey to its death.
The anglerfish, possibly one of the world’s ugliest creatures, is most famous for the bioluminescent growth on its head, which lures prey to its death at the the lightless bottom of the ocean.
However, there are more than 200 species of anglerfish, divided into four groups: goosefish, batfish, frogfish, and deep-sea angler. Only females possess the iconic, bioluminescent angling apparatus. Most live at the bottom of the Atlantic and Antarctic Oceans, sometimes as far as a mile below the surface.
Due to their long, tapered bodies, grenadiers are better known as “rattails.”
There are about 300 species of grenadiers, a large-headed fish found in warm and temperate waters.
Due to their long, tapered bodies, these rodent-like creatures are better known as “rat-tails.”
This ghoulish-looking creature is aptly named ghost shark, or chimaera.
Like sharks and rays, the ghoulish chimaera is a type of cartilaginous fish. It also bears an uncanny resemblance to Zero, the dog from “The Nightmare Before Christmas.”
Inhabiting temperate to cold waters around the world, chimera live at depths of 8,200 feet or more. There are about 47 species, which range in length from 24 to 80 inches.
Archaeological evidence has proven that chimera have been around for millions of years. The earliest fossil specimen, a skull, was dated to about 280 million years ago. It was unearthed in South Africa in the 1980s.
