Shark Fact!

In the Devonian period to the early Triassic, Helicoprions, a eugeneodont fish, which are an extinct shark-like group of cartilaginous fishes roamed the seas. The eugenedont had a unique feature, the spiraling "tooth whorls"

Because, like sharks, their skeletons were made of cartilage, almost all evidence of Helicoprions are fossilized tooth whorls, leading to past debate by scientists on where they were placed on the body. In recent times, it was found that they would fit into the lower jaw.

In the summer of 1975 the movie "Jaws" was released into theaters around the world. Although the movie was a massive success, it unfortunately perpetuates the myth that sharks are mindless killing machines.

In honor of the 50th anniversary, here are some small facts about Jaws!

- The author who wrote jaws, Peter Benchley, regreted the impact that that jaws had on sharks, and became an advocate for shark conservation until his death in 2006. The director of Jaws, Steven Spielberg has also expressed his regret towards the impact that his film had.

- One of the consequences of Jaws was the attitude that people had around the fishing and trophy hunting of sharks, leading to massive decrease in populations of sharks in North America

- The shark in the movie, nicknamed "Bruce," was made up of 3 different animatronic sharks, each with a different purpose. Bruce is 25 feet (7.62 metres) long .

- The average size of a great white shark is about 15-16 feet (about 4.5 meters) for females, and 11-13 (about 3-4 meters) for males.

- Footage of real sharks for the movie was filmed off the Australian coast.

While Jaws is undeniably one of the most well known pieces of media surrounding sharks, it has had a negative effect on shark populations worldwide.

Don't be afraid to enjoy the movie, it is one of the reasons I found my love of sharks, but remember it is a piece of fiction, and think critically.

Shark fact

Magamouth sharks are a rare species of deep sea shark. They are filter feeders, using their large mouths to eat while swimming through the ocean.

According to the Florida Museum, between 1976 and 2022 there had been 273 confirmed sightings of these sharks internationally, the large majority happening as by-catch in Taiwan, but there has been likely more unreported sightings by fishers who released them back into the water due to their large size(approximately 5 meters, or 16 feet in length).

Because of the rare sightings of the magamouth shark, scientists do not know how big their population is, making the conservation status marked as "least concern."

Shark Fact

Epaulette sharks, a small type of reef shark, can "walk" on land during low tides. They do this by their pectoral and pelvic fins evolving to be more like feet so that they can crawl outside of the water from pool to pool during low tide.

They are able to lower their hearts and the rate at which they need to breath to be able to go outside of the water.

Walking on land allows for better hunting as well as to move to more oxygenated pools of water.

the twitter thread the artist created after this was one of the best situations i have ever seen in my whole life:

[serpentking456]

Somebody give this ignoramus a piece of actual shark skin and tell him to rub his face with it, let him find out just how “smooth” sharks really are.

[bransonreese]

Somebody did. I use it as a pillowcase because it’s so smooth.

[severepaperhideout-deactivated2]

But buddy.

Shark skin feels exactly like sandpaper. It is made up of tiny teeth-like structures called placoid scales, also known as dermal denticles. These scales point towards the tail and help to reduce friction from surrounding water when the shark swims. … In the opposite direction, it feels very rough like sandpaper.

Buddy. It’s smooth. The link you sent me led to a website that described how smooth they are. I dunno, maybe you don’t know how to read?
