This really cute Creature is called "Dumbo Octopus".

Dumbo octopuses (Grimpoteuthis sp.) live in the deepest, darkest regions of the Atlantic and Pacific, making them extremely difficult to study. A rare surprising sighting around 2018 happened about three kilometers below the ocean surface, while others have been discovered twice as deep. The animals spend most of their lives close to the seabed, where they lay their eggs and hunt for their food, which mainly consists of crustaceans, mussels and worms. They are also the deepest living octopuses known.

Thought this was interesting I always assumed it was from our vast forests alone.

Half of the oxygen we breathe is produced in the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.

A narwhal's tusk is the only straight tusk in the entire world. All other tusks (e.g., those seen on elephants) are known to curve. Instead, a narwhal's tusk always forms a left-turning helix spiral. Even when an individual grows two tusks, which happens in rare cases, they will both always spiral to the left, never to the right. / yay, ocean unicorns!

Ocean wave energy is being used to both power and transmit data to the cloud, for an ocean monitoring, multi-country data collection system called the Ocean Internet of Things! This is very useful, being a constant supply of energy in any weather condition! (vs. solar power or wind power out on the ocean, for example, which rely on weather patterns to be most efficient). So cool and super useful and relevant!

Humans have better maps of Mars' surface than we do the bottom of the ocean! We have are able to map 24.9% of the ocean floors in high resolution, which means we know more about the surface of an alien planet than we do our own oceans. Spoopy.

Modern day reef systems consist largely of Scleractinian coral, however Scleractinian corals didn't evolve until the middle Triassic about 240 Ma. Before then, reef systems appeared very different as they were made of other organisms! Around 3.5 billion years ago, reefs consisted of stromatolites (structures formed by cyanobacteria), and then from around the Cambrian (500 Ma) until the end Permian (252 Ma) reef systems were made up of sponges, bivalves, tabulata corals(extinct) and rugose corals(extinct)!

There was a prehistoric ocean that covered the middle of North America. It’s called the Western Interior Seaway and existed from 100-66 million years ago which would be the late Cretaceous to early Paleocene periods.
I’ve heard this said to be why certain fishy fossils and seashells can be found in the Midwest (the most landlocked part of the US!) though that part of this I can’t necessarily vouch for, I just know that as a kid learning about the prehistoric shallow ocean that once covered my homeland was amazing to my awe-inspired heart!

The first written mention of a unicorn was in the 4th century B.C. by the Greek physician Ctesias in his book Indica

Description:
Ctesias described the unicorn as a large, pale blue-eyed ass with a crimson head and a horn of white, red, and black. He said they were fleet of foot and had a horn that was a cubit and a half in length.

The Slender Snipe Eel has more vertebrae than any other vertebrate on earth- counting in at over 700! Lookit that skeleton!

Jellyfish have one of the fastest movements in the animal kingdom... Their stinging cells, called cnidocytes, contains a harpoon-like structure called a nematocyst. It takes the jellyfish on 700 nanoseconds to release this nematocyst once triggered, shooting venom into its prey or the unlucky person who brushes against their tentacles.
