earth fact time. this is NOT A DRILL! two great white sharks have become best friends!! their names are simon and jekyll and they've travelled together for over 4,000 miles. this is a huge discovery, because great white sharks are usually solitary creatures!
an important note is that these sharks aren't swimming side by side, and are usually a couple kilometres off from each other - but their trackers kept pinging in the same part of the ocean at the same time. scientists think they might be brothers, or following a previously unknown migratory path.

can you do one about vampire squids ? 🦑
Tumblr media
Vampyroteuthis infernalis or Vampire Squid
It's (very dramatic) scientific name means "vampire squid from hell". However, the vampire squid is not actually a squid! It's actually the only animal in the Vampyroteuthidae family! It's separated into its own family because it can't change color or produce ink. Instead, it turns itself "inside out" (as shown above) to deter predators.
Tumblr media
Proportionally, vampire squids also have the largest eyes compared to their body size! They eat mostly zooplankton, marine snow, and other organisms waste. They grow to be about the size of a football and live to be around 8 years old.
Tumblr media
There's even evidence that vampire squids have been around since the Jurassic period- almost 200 million years ago!

Daily fish fact #743
Wahoo!
Tumblr media
This speedy pelagic fish seems to be attracted to flotsam and tall objects! They're broadcast spawners, releasing their eggs into open water without any parental care.

🍪 Feeling hungry? Well, despite its name, the chocolate chip sea star (Protoreaster nodosus) probably wouldn’t taste very good. To start, those “chips” aren't chocolate at all… they’re tubercles, or knobs, and they’re unique to each sea star. No two individuals have the same arrangement of tubercles!
Like many other sea stars, this marine invertebrate eats by pushing its stomach out of its mouth, covering its meal, and then digesting it externally. This critter inhabits the warm waters of the Indian Ocean and Pacific Ocean, where it might be spotted around coral reefs or seagrass beds. It can grow up to 12 inches (30 cm) across.

Idk about y’all but valentines memes have been my favorite part of the holiday since I was an inappropriately young child on the internet
So I made some cephalopod themed ones for your enjoyment <3

Most sharks are negatively buoyant, meaning they naturally sink in water. However, in 2015, two deep sea sharks - the bluntnose sixgill shark (top) and the prickly shark (bottom) - were discovered to be positively buoyant, meaning they naturally float in water.
This could have one of two purposes: aiding stealth hunting by enabling them to ambush prey from below by motionlessly rising towards them; or for migrating to warmer waters closer to the surface at night to warm up the muscles (to then actively swim back down to colder waters during the day).

🐠 Daily Fish Fact: 🐠
The Oarfish is the longest bony fish alive, growing up to 56ft in length. Their rarity and large size, along with occasional beachings of oarfish after storms, and their habit of lingering at the surface when sick or dying, make oarfish a probable source of many sea serpent tales.

brown shysharks!
Tumblr media Tumblr media Tumblr media Tumblr media
brown shysharks are a species of catshark and they reside in the coastal, shallow waters of south africa!
when frightened, this shark curls up with its tail over its eyes, hence the name shyshark
they are around 60-68 cm long and they feed on bony fish and lobsters!
they are typically found in shallow rocky zones to a depth of 110 feet (35m)
they are the largest of all species of catshark
the brown shysharks’ predators are larger sharks and fish, as well as the egg-case-eating mollusks!

Convergent evolution is the evolution of 'analogous' or similar structures in organisms that are not closely related. Such as the wings of insects, birds and bats. One potential example of this is the Diplomoceras maximum, an extinct squid-like creature who is clearly analogous to, or a distant cousin of Clippy the paperclip. This amazing creature lived 68 million years ago, with the most notable fossil found at the cephalopod rich López de Bertodano Formation of Seymour Island, Antarctica. An area that was formerly warmer before further movement of tectonic plates. The fossil shell measured an impressive 1.5 metres and is formed from ridges, speculated to grow a section annually. These ribs are thought be similar to tree rings, being used for dating samples and gaining insight about the environment of the prehistoric sea, such as measuring the carbon and oxygen isotopes in the shell.

Like, I know tube worms are worms. I know that. But.
Tumblr media
I think actually they're Ahh! Real Monsters more than anything else, you know?
Tumblr media
Giant tube worms are an iconic resident of hydrothermal vents. Hydrothermal vents are extremely cool, because they're one of the uncommon ecosystems that can survive independently from the sun!
Sure, lots of ecosystems live in the dark, but a lot of the food in those ecosystems, at their base, come from sunlight. Something at the surface consumes sunlight, makes energy, then dies and falls or gets eaten by something that swims downward, etc.
These giant tube worms are full of bacteria that are able to eat the chemicals that seep out from the nutrient-rich plumes created by the geology of hydrothermal vents. Basically, the seafloor has cracks, water falls into those cracks, the water gets super hot from the magma below, picks up minerals, then spews out in these different kinds of "plumes". Some are full of iron oxide and come out super dark (Black Smokers), whereas others, full of barium, calcium, and silicon are white (you guessed it, White Smokers). The tube worms live in communities with other deep sea weirdos like Yeti Crabs, clams, and many more.
Hydrothermal vents aren't the only places in the ocean where bacteria (sometimes paired with animals, sometimes on their own) make energy straight from chemicals, but they're probably the most iconic!

Any fun facts about basking sharks? (Really big sea puppies)
Tumblr media
Cetorhinus maximus or Basking Shark
These are the second largest shark and fish in the world (after the whale shark), they can grow to be 12 m (40 ft) long!
Also like whale sharks, they're ram filter feeders. This means that to catch prey, they simply open their mouths, swim forward, and catch whatever happens to get in their way! This is why they (and other ram filter feeders) tend to have such large mouths. The basking sharks mouth can be up to 1 m (3ft wide).
Tumblr media
While sharks are mostly thought to be solitary creatures, a lot of species do school and the basking shark is one of them! They're usually divided by sex (except during periods of mating), and schools of over 100 females have been spotted!
Tumblr media Tumblr media
And probably the coolest fact about them- THEY CAN JUMP OUT OF THE WATER. Despite weighing around 5,000 kg (approx. 11,000 lbs) they can breach 1.2 m (4 ft) into the air! It's believed they do this as a method to remove parasites.

Daily fish fact #714
Mandarinfish!
Tumblr media
The mandarinfish is one of the only vertebrates to produce blue cellular pigment! Most other blue vertebrates’ colour is caused by structural colouration, as in microscopic structures that reflect, refract and otherwise alter light. The mandarinfish and its relative psychedelic mandarinfish possess cyanophores, however, which contain blue pigment itself!

Meet the Caribbean reef octopus (Octopus briareus)! This reef-inhabiting cephalopod lives in warm shallow waters, spanning southern Florida to the Caribbean, through to South America’s northern coast. It’s distinguished by its eye-catching blue coloring, but this master of disguise can change its looks in an instant. Like other octopuses, it uses pigmented cells in its skin, called chromatophores, to alter its appearance. When confronted by a foe, such as a shark, it may emit a cloud of unpleasant-tasting ink to deter its enemy from further pursuit.
