Biology. Dragon Sharks are a large and dangerous type of shark. They have very rough skin similar to a Sharpedo, but are nearly unmatchable in speed underwater. A unique aspect of the dragon sharks is that their front fins have clawed fingers and their tail fins are horizontal rather than vertical.
The Goblin Shark Is not as Scary as It LooksThe Goblin Shark mostly feeds on fish, mollusks and crab, and it poses no real danger to humans. It lives in very deep water, far from humans, and it is thought to be a poor swimmer and have bad eyesight. There are no reported incidents of Goblin Sharks attacking humans.
Frilled sharks have been living in the deep ocean for 80 million years, but little is known about them. A rarely seen creature from the deep sea was recently pulled up from the ocean near Portugal.
But that's because it's perfectly adapted to life in the abyss. So called because of the fluffy appearance of its gills, the frilled shark has six gill slits on either side of the head. It's thought to hunt along the seabed using its senses to find its prey, and when it does it lunges at it like a snake.
A new study suggests that a tsunami of cosmic energy from a supernova killed off large ocean animals – including the huge megalodon shark – 2.6 million years ago. A shower of particles may have spelled curtains for the megalodon, a school-bus-sized shark, 2.6 million years ago.
Extinction of a mega sharkWe know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. Precisely when the last megalodon died is not known, but new evidence suggests that it was at least 3.6 million years ago.
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. Amphipods are shiny, shrimplike scavengers commonly found in deep-sea trenches. The holothurians may be a new species of bizarre, translucent sea cucumber.
Because of its extreme depth, the Mariana Trench is cloaked in perpetual darkness and the temperature is just a few degrees above freezing. The water pressure at the bottom of the trench is a crushing eight tons per square inch—or about a thousand times the standard atmospheric pressure at sea level.
34 to 39 degrees Fahrenheit
A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench.
The Portuguese Dogfish is a species of Sleeper Shark known to survive at depths of up to 12,000 feet. The Pacific Sleeper Shark and Greenland Shark are huge animals reaching over 20 feet in length which can live at depths of up to 9,000 feet. Even the great white shark has been recorded diving to depths of 4,000 feet.
While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
Frilled sharks, Chlamydoselachus anguineus, are an uncommon “primitive” shark species typically found near the sea floor in waters over outer continental and island (insular) shelves and upper slopes, usually at depths between 120 and 1,280 m but up to 1,570 m and occasionally even at the surface.
Goblin Shark Facts Overview

|---|
| Color: | Pink, tan and almost white grey |
| Diet: | Fish, such as rattails and dragonfishes as well as cephalopods and crustaceans. |

The goblin shark feeds mainly on teleost fishes such as rattails and dragonfishes. It also consumes cephalopods and crustaceans, including decapods and isopods. Garbage has been recorded from the stomachs of some specimens.
Frilled sharks are eerie-looking deep sea sharks that resemble eels. They are named for the six gill slits on either side of the bodies, which are frilly-looking in appearance.
In this tutorial, we will draw Frilled Shark.
- How to Draw a Frilled Shark.
- First start the tutorial by drawing an oval & a circle.
- Draw curve line.
- Make head, eye & jaw.
- Draw outline for body.
- Make tail.
- Make fins & gills as shown.
- Draw eye & lines in the middle of the body and over the tail as shown.
