If You're Feeling Anxious Or Depressed About The Climate And Want To Do Something To Help Right Now,

Day two of drawing dumb little sharks until I learn how to draw sharks: The thresher shark! I spent more time on this one and I hope it shows! Also if you know how to draw sharks id love feedback! This lil guy uses his tail as a sort of whip in order to bonk their prey. A thresher sharks tail can be up to 3 meters (around 9 feet) long on the common thresher sharks (the biggest ones)! Also did you know that they're also referred to as the fox shark? I think thats pretty neat :)

Listen to me, boy. You will hear about sea slugs. You will enjoy sea slugs

Costasiella kuroshimae / leaf sheep. Discovered off the coast of Japanese island Kuroshima in 1993, they can indirectly perform photosynthesis by absorbing chloroplasts from algae

Cyerce nigricans. The cerata can be easily cast when disturbed. They can also swim by powerfully flapping said cerata when strongly stimulated. I think they look like butterfly wings!

Jorunna parva / sea bunny. They are covered in papillae, which are fleshy protuberances used for sensory functions. It looks like fur!

Glaucus atlanticus / blue glaucus. They are rarely seen, except during periods of on-shore winds which brings them and their prey into coastal waters. They are the most dangerous sea slug to handle, able to give humans a very painful and potentially dangerous sting

Chromodoris lochi / loch's chromodoris. They are spongivores, and prefer being on the underside of overhangs on rocky reefs. Their distribution is widespread in the Indo-Pacific. Everyone I show sea slugs to seems to love this little guy

Dirona albolineata / white-lined dirona. A translucent predator that often eats bryozoans and small snails. They generally reside on rocks and sometimes mud in the intertidal. Pretty little things, they remind me of shards of glass

Phidiana hiltoni / Hilton's Aeolid. They are known for being quite aggressive, often biting and fighting other aeolids, which is so real of them. They always reminded me of lit matches

Acanthodoris lutea / orange-peel doris. Its bright aposamatic colouration is a warning to predators of its distasteful toxicity. They also notably smell of sandalwood! You don't understand. I NEED to hold one

Nembrotha kubaryana / dusky nembrotha. They use the toxins in their prey ascidians to defend themselves against predators. The toxins are stored in their tissues then released in a slimy defensive mucus when alarmed. Nembrotha kubaryana are well-known for their neon appearance

Phyllodesmium poindimiei / Spun Of Light. It's primarily nocturnal and can cast its cerata for protection. Anyway, can we all agree that Spun Of Light is the most awesome name for a sea slug ever? I mean, look at it. That's a sea slug spun of light if I've ever seen one

Conclusion: sea slugs are the creatures ever

17th of October 2024: Creseis virgula

Today we are returning back to the ocean to look at a critter without a common name: Creseis virgula. They’re a type of mollusc who can be found in tropical waters all around the world as well as in the Upper Atlantic [1]. Their species name derives from the latin for small rod [2].

They are indeed quite small, having a maximum length of 7 mm, with their shell being entirely transparent and characterised by a small curve at the top while the front is straight. The curve is a lot more prominent when they are still young. Their bodies meanwhile can be recognised by their small wing-like appendages [3].

They are most common during the late summer and autumn when the temperatures are still rather high. During this time they reproduce a lot [4]. Creseis virgula are protandric hermaphrodites, meaning they start off life as males who may change into females later on [3].

They feed on phytoplankton and protozoa, and have been described as a “clumsy swimmer” [3]. If they ever need to be the ones to escape, they may drop a feeding web made of mucous and sink down with the tip of their shell pointed downwards [5].

Byzantine history be like:

In 874 Emperor Kostalogous IV ascended to the throne after blinding sixteen nephews, and married his wife, Theodora.

However, he soon ran afoul of the Patriarch of Constantinople, Theopelagionikus, and his wife Theodora.

In 895 he was deposed by his general, Justiniapelomaxorianous II, and his wife Theodora.

This created nine new church schisms.

Orchid plants nurture their seedlings via shared underground fungal network, study shows

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by the wind, yet they often appear in clumps with small seedlings growing near mature plants. This phenomenon has puzzled ecologists since Darwin's time, with the exact reason remaining a mystery. A new study, led by researchers from the University of Sheffield in collaboration with The University of Manchester, provides the first evidence that early stage orchid seedlings germinate and thrive near to adult plants due to a kind of parental nurture using underground fungal networks. Scientists investigated the idea that fungal networks, known as mycorrhizal networks, act as a direct pathway for established orchid plants to share recently produced sugars with developing seedlings.

i am in awe!!!!

I just discovered the blanket octopus. Would you do a fact on them if not already done? 👀

Sure friend! I am a daily fish fact account only, but I simply couldn't not say something about the magnificent blanket octopus :)

Here is a blanket octopus female! How do I know that? Simple: the males of the species only reach about 2 and a half centimeters, while the females can be as large as two meters long! The species is named after this gorgeous lady's webs that connect to her arms.

"Blanket octopus" refers to four different species actually! And they're all immune to the extremely venomous Portuguese man o' war, young females and males will in fact rip out a dangerous and venomous tentacle from these animals to defend themselves! It is extremely interesting and exciting what kinds of things octopuses are capable of :)
