Black Shark

It stalked us for days. We could see its fin drawing circles around our boat, and at night its teal glowing eyes were visible underwater. Never before have I been this scared. We were certain it would tear down our boat. The sheer size of this shark was phenomenal. Yet for some reason it left us alone eventually.

The black shark, also known as great black or black terror, is an apex predator roaming the seas all over the world. It is believed to be the largest shark on the planet. While they usually hunt other large sea animals they are also known for attacking ships when they are hungry and no other food is around.


Black sharks are robust-looking sharks which are notable for their size and inflicted nature. Their skin is black with dark grey stripes on top, and a dappled light grey on the underside. Each specimen has a distinct pattern of cuts and tears on their body, not due to past wounds but rather because they are born this way. It is believed that their shabby appearance is due to their inflicted nature. Proof of that are their teal glowing eyes, two on each side of their conical shaped head (Four in total). Females are larger than males. Black sharks keep growing all of their lives. The larger the shark, the older it is.


Not much is known about the black sharks mating habits. It is believed though that the gestation period takes about 13 months. One female can give birth to 4 - 15 pups. They reach sexual maturity around the age of 30 (males) and 35 (females). The pups remain with their mother for several years until they are large enough to survive the oceans on their own. Despite their lack of natural predators black sharks are uncommon. This is largely due to their slow maturing and long gestation period.

Social Behaviour

Although lone black sharks have been sighted on more than one occasion they tend to live in small packs of 5 to 15 individuals. They have a dominance hierarchy depending on the size, sex and squatter's rights: Females dominate males, larger sharks dominate smaller sharks, and residents dominate newcomers. When it is time to feed they separate and hunt independently of one another.

Diet & Hunting

Black sharks are excellent hunters. They have exceptional smell and sight and seem well equipped to spot prey at a large distance, even if that prey is motionless. One of their more dangerous features is that they somehow can make themselves impossible to spot. It is unknown how they do this, although their coloration does help as well. They feed on anything they can dig their teeth in. This can be seals, squids, birds, whales and even smaller sharks. Black sharks show above average intelligence. When they are hungry and no other food is in sight they can attack boats and even large ships. They seem to know their is prey on board. Their powerful jaws can easily crush boats and even larger ships are not always safe. They are very curious animals, so when a black shark stalks a ship it does not always mean the crew is in danger. Sometimes they merely follow along to go their own way after their curiosity has been satisfied.

Habitat & Geographic distribution

Black sharks can be found in almost all seas with a water temperature between 10 and 25°C. Younger sharks can often be found in coastal regions, while the larger ones prefer deeper waters.

Species | Dec 21, 2020

A group of species linked together due to the condition that forced their original ancestors to mutate into new monstrous species.

I am sure we will be branded lunatics, but we all saw it. Black sharks can make themselves invisible! I am the first to admit their colors make them hard to spot in the sea. But this was way more than mere camouflage. We could see its dorsal fin clearly as it swam closer to the seal colony, and then it disappeared. Not because the shark submerged itself underwater. No it disappeared because it became invisible. We are certain of this because we saw some unseen force lifting an unfortunate seal into the air a moment before the shark reappeared. The seal crushed between its teeth.

Thank you so much. I would probably die from fear if such a beast was swimming around the ship I was on.

Shark are between my favourite animals, for my honeymoon I went to Cuba and wanted to submerge with a cage to see Mako Shark but my wife said that she didn't want to become widow so early, now she says she'd let me go next time! :P

Haha, good luck. I don't think I want to ever be near a shark.

Whoa! Sharks scare me enough, so this is really cool. I find it kind of interesting they are called black sharks like the great white sharks here in our world. Huh. Was that done on purpose or just kind of...came that way? :p   In particular, I really like their social behavior! Never thought about a hierarchy like that for animals. Their curiosity, while terrorizing, makes them... I don't know, kind of cute? XD

It was unintentional. I remember I used it in a quote or something along the lines of: ... as deadly as a black shark. And at the time I just needed something deadly. I thought of a shark and black sharks apparently don't exist in our world, or at least I could not find info on them. So for the apex predator prompt these were ideal to write about. Thanks for your comment Mar. :)

Of course for this article I did look up info on great white sharks, tiger sharks, megalodons, and such. :) So great black as nickname comes from the great white sharks. :D

I think my favourite detail is the fact that they have four eyes. And that they are massive!

These are terrifying and fantastic! Great article, I reached the end and wanted to read moooooore! Do they prefer certain temperatures of oceans, or avoid any?
