Whale sharks are known as gentle, bespeckled giants that swim in tropical seas and scoop up plankton with their cavernous mouths. According to new research, they also have a sharp eye—literally: their eyes are covered in tiny teeth.

The “dermal denticles” are modified, tiny teeth that cover the whale shark’s eyeballs.

Whale sharks’ eyes have no eyelids and poke out on either side of their heads, which makes them vulnerable to exposure. Eyeball teeth, probably serve as protective armor against the elements.

Sharks predate trees by over sixty million years.

Your ordinary run of the mill shark may have around 20,000 genes.

A simple flowering tree has twice as many.

Sharks also predate the rings of Saturn and the formation of the North Star.

Sharks have existed long enough for our solar system to make a galactic orbit. Twice.

An unusual entry technique 🤣

If you look really closely, you can see the mistake Comment your answer below ⬇️ But in all seriousness, Agustin our dive master trainee asked us to film him doing a cool entry… and slipped at the last second He’s completely fine 🙌 but it’s a good reminder that safety starts before you even enter the water, not just underwater. Stay sharp, stay safe 🤿 . . .#scuba #buceo #tauchen #diving #plongee

“The month of Ramadan is the one whose beginning is mercy, its middle is forgiveness, and its end is freedom from the fire.”

A very good question 😳

Who wants to live forever?

The Immortal jellyfish, that’s who!

The immortal jellyfish, known as Turritopsis dohrnii, has the ability to reverse age and theoretically live an eternal life. Because of its ability to regrow its cells, it could theoretically escape death over and over again.

The life cycle of the immortal jellyfish is what makes it extraordinary. Like most jellyfish species, it begins life as a larva, which settles on a surface and grows into a polyp, which is a blob-like cyst. This is the stage where the jellyfish is still attached to the sea floor.

This polyp then transforms into a medusa, which is the free-swimming stage of an adult jellyfish. And the medusa is generally the final stage of a typical jellyfish's life before it dies.

But immortal jellyfish — when faced with stress, injury or starvation — have the ability to revert back into a polyp. Through a process known as transdifferentiation, they are essentially resetting their biological clocks to cheat death.

The reincarnated polyp eventually produces new medusae that are genetically identical to the previous version of the immortal jellyfish. This process is called transdifferentiation, where mature cells transform back into stem-like cells or polyp cells, allowing for regeneration of a whole new body.

The immortal jellyfish can repeat this life cycle reversal indefinitely, which helps it survive in changing environments and unfavorable conditions.

In reality, because the immortal jellyfish is tiny and easily preyed upon, the immortal jellyfish is frequently eaten by fish, sea turtles, slugs and other sea creatures — so they are perfectly capable of dying.

But even if they do regenerate forever, this begs a question of science fiction and philosophy: If all of an immortal jellyfish's cells are replaced but perfectly duplicated, is it technically the same jellyfish?

Scientists have been studying the immortal jellyfish to see if they can learn anything about extending the lives of people.

Though human beings may not be able to magically revert to a youthful state in the same way, the research may give new insights into stem cell research, as scientists discover new ways to replace cells that have been damaged by disease.

Here we have the headless chicken monster, also known, confusingly, as a Spanish Dancer. Unlike the nudibranch Red Sea divers are familiar with though, the headless chicken monster (come on, that name has got to raise a smile at least) is a cucumber and one of the few that can swim with a specially developed flap that it uses as a sail or fin.

The headless chicken monster - 🤣 - was discovered in the 1870s by scientists aboard the HMS Challenger during its famous oceanographic expedition. Headless chicken monsters (or Enypniastes if you want to be scientific) live across all oceans, including near Antarctica, at depths below 500m (1,600ft) and down to at least 6,000m (approx 19,600ft).
