Reblog If You Want People To Send You Asks.

The person I reblogged this from deserves to be happy

I tried to scroll past this. I really did

this song at 5am before rowing <3

Greetings and salutations! You seem very cool/interesting/friendly! (I found your intro post when looking through the marine biology tag (I know nothing about marine biology but find it immensely fascinating)

Tell me about bioluminescence :)

omggg hiiii i literally just made my account today, i didn’t think anyone would actually see it!! u seem rly cool too 😊

i am waaaay too into bioluminescence, mainly marine bioluminescence bc it’s cool 🙃 76% of discovered deep sea creatures use bioluminescence! so basically, the light is produced from a chemical reaction from luciferin and oxygen:

luciferin (C11H8N2O3S2) + oxygen (O) —> light and oxyluciferin (by-product)

and organisms either have an enzyme called luciferase, which catalyzes the reaction, or photoproteins, that allow the reaction to occur. the reaction occurs in the cells of an organism (or cell if it’s only a single-celled organism)

some animals, like firefly squid, have photophores, which are like tiny bioluminescent dots along their body. they are the brightest type of bioluminescence and are sometimes complex enough to be able to detect light levels so the animal can control how bright the light they produce is. they are tiny glands/organs that have the necessary chemicals to produce light.

some animals, like hawaiian bobtail squid, have a symbiotic relationship with bioluminescent bacteria.

like the angler fish has bioluminescent bacteria living in its esca (glowing bulb thing)

and some animals just eat bioluminescent organisms and that makes them glow.

bioluminescence underwater is usually blue bc it travels furthest in water.

some animals use it to lure prey to them, such as dragonfish, who has transparent teeth so it doesn’t reflect light off them and give them away. some animals also use it for defence to confuse predators, like the pandalid shrimp just vomits bioluminescent mucus at predators, and vampire squid will do the same thing but only in a life-or-death situation bc it uses a lot of their energy. it is also used to attract mates in a few species.

bioluminescence is also used for camouflage, so that predators below can’t see the silhouette of prey above it because they match their bioluminescence to the sunlight’s brightness. it’s kinda hard to explain but it’s called counterillumination

the coolest bioluminescent organisms are vampire squid, glass octopuses, pyrosomas, helmet jellyfishes, cockatoo squid, and siphophore colonies

anywayyyy i hope you liked my very very long yap and you learned something!!! and thank you soooo much for following me and sending me a message 😊😊😊😊

Keep the flame going for those we have lost to suicide. 

moss growing in cracks in the pavement is actually so beautiful

omg moon jellyfish are gorgeoussss 😊 they’re so pretty and magical

Hiya! I just found Ur account cos Ur silly lil shark drawings came up on my dash and omg U seem super cool! If U want to yap, I adore jellyfish so would love to hear anything abt them! Alternatively tho you could yap about literally anything to do with marine bio and I will absolutely read lol. Anyways omg I'm sure this account is gonna be such a slay, from one ocean-obsessed INFP to another🌊💙

hiiiiii!! nice to meet u! 😊 ur account is literally so cool omg 😍🌊

jellyfish are soooo cool!! do u have a favourite type of jelly?? i think i like the atolla jellyfish or helmet jellyfish. there are a lot of jellyfish in the river where i do rowing training, they’re these brown ones, i think they’re called australian spotted jellyfish.

the cute little brown jellies and the sunrise at the rowing shed 😊

atolla jellyfishh (or deep-sea crown jellies i think) look like tiny little UFOs. they’re about 15 cm wide. they have a bioluminescent bulb that they use to disorientate and confuse predators that are threatening them, and allowing them to swim away. also they eat plankton.

there is also a type of jellyfish which is called an immortal jellyfish that can revert back to a polyp when it is physically injured as an adult, and then regrow to be genetically the same as an adult again. they do this through transdifferentiation, a process where cells that are specialised for a specific tissue can turn into a different type of cell that is specialised for another tissue. they are also reallllyyyy small, less than half a centimetre big fully grown.

anywayyy tysm for ur message!! i hope u learned something!!!

also i hope u liked my shark drawings 🙃🦈

awwww she’s adorable!!! she looks so majestic

so many people have dogs named ziggy, one of my friends irl also has a dog called ziggy

There’s a “cat checkpoint” post going around, so this is a

Reblog with the last picture of a dog in your camera roll.

yayyy tysm!!!! 😊 i think ur really really cool too! and thanks for letting me yap to u about bioluminescence, it made my dayy ✨

Yayy new moot! And she's a marine biologist!!

( @ang3l-ocean i think you're immeasurably cool )

idk, my little sister named my dog Ziggy and i don’t think she knows anything about David Bowie… she listens to brainrot songs and nothing else 😭😭

but the other Ziggy i know irl im pretty sure is named after ziggy stardust
