„Researchers documented an enormous uptick in RNA editing when cuttlefish, octopus and squid acclimated to cold water. Because editing changes RNA only temporarily, the researchers suspected these animals use it to acclimate to their environment.“

"The data presented in this paper definitely suggests that cephalopods have among the oldest sex chromosomes in both animals and plants," independent evolutionary scientist, Sarah Carey, told Carissa Wong at Nature.

new study led by #GEOMAR provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

Cranchiids are wonderful.

From the massive colossal squid (Mesonychoteuthis hamiltoni), to the surprisingly long Galiteuthis phyllura (Up to 2.7 m in mantle length!), to the depressed looking Taonius borealis to the very silly Cranchia scabra...
A photo of a colossal squid (Mesonychoteuthis hamiltoni). It is in the water but caught in a fishing line. It has a large mantle and fin. A photo of Galiteuthis phyllura swimming in the ocean. Its body is transparent, except for one of its organs, eyes and some chromatophores which are reddish. Its limbs are translucent with orange tips. Two photos of a Taonius borealis. The squid has deep red chromatophores all over its body. The first photo is from straight on and slightly above. Its eyes are looking down, its limbs are all pointing straight up, and its mantle is going straight back. The second photo is in front of its head. It is looking forward with sad, depressed eyes and its limbs are up and going back. Its mantle is going back and slightly down. A Cranchia scabra swimming at night, with its fins flapping and its limbs are hanging down. It is a ghostly blue and its eyes are a soft red. Its mantle is inflated, so it is an elongated sphere or gridiron football shaped and is covered in tubercules.

Also the study found that they do have stereo vision

Scientists Velcroed 3-D Glasses to Cuttlefish to Study Their Depth Perception

In 2019, scientists wanted to test if cuttlefish had stereo vision. So they did what any reasonable person would do:

They velcro'd 3D glasses to European common cuttlefish (Sepia officinalis) and set up a 3D theatre.

The results? They look very cool

Their arms are reaching out and they have a sandy striped pattern A European common cuttlefish (Sepia officinalis) wearing a pair of red and blue 3D glasses swimming just above the ground. They look very cool. They have a yellow sandy beige colour. A European common cuttlefish (Sepia officinalis) wearing a pair of red and blue 3D glasses reaching for a projection of a shrimp. They look pretty cool. They have a sandy brown colour. A European common cuttlefish (Sepia officinalis) wearing a pair of red and blue 3D glasses sitting on the ground. Their two centre arms are raised and reaching back while the other limbs rest on the ground. They have a grey colour with brown spots. They look extremely cool.

Scientists at UC San Diego wanted to study how squids were able to survive in tropical regions and near-arctic regions with waters just above freezing. They found squids do this by constantly editing their genes to allow them to adapt. 🧬🦑
