10 Cool Facts About Sharks for Shark Week

Shark Week is  de-fin-nitely Jawsome!

Sharks are amazing, beautiful creatures. Unfortunately, they have a bad reputation which is very misleading. These slick creatures who are part of our ecosystem are pretty cool and beneficial to our planet! We have put a list of 10 cool facts about the shark that might give you another perspective on the stealthy and impressive fish.

Alone from the Start

When baby white sharks (called pups) are born, usually by the dozen, they swim away from their mother who see them as prey. From day one, white sharks are on their own and have to quickly learn how to be stealthy as they are easy prey for bigger sharks. When a pup is born, it measures on average 1.5 meters (5 feet).

One Big Meal at a Time

White sharks can last one or two months without a big meal! When they hunt, these sharks will usually go for large mammals such as seals or sea lions. When they catch one, it can satisfy them for a month or two until they hunt again, catching small prey, like other fish, in the meantime. Sharks also don’t chew their food! They rip of chunks of meat from their prey and swallow them whole.

Not so Scary

People have unfortunately learned to fear sharks because of bad reputation and movies such as “Jaws” when, unfortunately, it’s sharks that have to be afraid of us! More than 100 million sharks die each year because of us. Humans have become sharks’ most deadliest predator over the years. Most of it is because of shark finning, where fishermen remove shark fins for later human consumption, specifically shark fin soup served in the biggest part in China. The sharks are then released back into the ocean where they are still alive but sink to the bottom and often are eaten alive by other fish.

Hey there Grandpa!

Sharks are even older than dinosaurs! It is estimated that sharks have been swimming around for more than 450 million years and have survived all 5 mass extinctions during the past 493 million years! Tough cookies? Yup! The Megalodon, which existed 16 million years ago, could reach sizes of 15.25 meters (50 feet) in average! They were huge predators compared to today, but sharks are still kings and queens of the ocean. That is if humans stop killing them senselessly.

Red Hot Chili Peppers

The Aztecs as well as the Kuna Indian tribe of Panama used to tie strings of chili peppers and spicy solutions to their boats to keep sharks away. The team over at Mythbuster, however, debunked this theory as sharks who would bite into spicy animal remains were not even phased by the taste.The chili peppers were more of lucky charms than they were repellents!

All you can Eat Buffet

Blue sharks, unlike Great Whites, eat and eat and keep on eating! They are hardly ever satisfied with their meals and will regurgitate after having eaten, and then will ask for more! Blue sharks usually feed on small fish and squids.

“Like, whatever!”

Great white sharks do not close their eyelids but instead roll their eyes to the back of their head when they attack on prey. This prevents debris from hitting the shark’s eyes as they swim quickly to the surface and also protects their eyes from their prey’s trashing about.

Because of the Full Moon

Sharks are affected by the full moon and its control over ocean tides. Eating habits have been noted to change during full moons and draws sharks closer to shore. When sharks are closer to the shore and the tides quickly become low, people are closer to sandbars and the sharks are closer to them, making them susceptible to being attacked. So during full moons, stay away from the ocean’s shore!

Don’t need no man!

Some female sharks, once in a while, can reproduce without a male! This phenomenon is called parthenogenesis, where reproduction from an ovum is caused without fertilization. So some female sharks fly solo! Scientists have documented a few cases, however, in the right circumstances, most female sharks can get pregnant on their own.

Not So Cold-Blooded

The Great white shark, contrary to most fish, is warm-blooded. This allows the creature to adapt to different water conditions as it can regulate its own body temperature. Pretty cool!
