The octopus squid breaks the rules, having 8 arms instead of 10

- The octopus squid (Octopoteuthis deletron) is unusual among squids. Typically, squids have eight arms and two long tentacles, making a total of 10 appendages. But as young Octopoteuthis mature into adults, their two feeding tentacles are reabsorbed into their bodies.
Eight arms are not the only thing that stands out about this species. While exploring the midwater, we often encounter octopus squid in a distinctive posture: large fins spread wide, and arms with twinkling tips curled above the head. Light-producing organs called photophores flash with bioluminescence at the end of each arm.
MBARI has spent several decades studying Octopoteuthis. Cameras on our advanced underwater robots have revealed insights into the mysterious lives of octopus squid, from their unique behaviors to their defensive strategies. Octopus squid and their deep-dwelling kin play a vital role in ocean food webs. Despite their ecological importance, we still know very little about the lives of deep-sea squids. MBARI’s work is answering fundamental questions about deep-sea cephalopods and providing vital information that resource managers can use to inform their decision-making about the ocean.
The deep sea is closer than you think. What we do on land affects the ocean, even the animals and environments deep below the surface. By choosing sustainable seafood, refusing single-use plastic, and reducing our carbon footprint, we can help protect the amazing animals of the deep.

Keep up the great work MBARI and those involved with keeping us informed, always appreciated.
Never seen a Sleeper Shark that looked so clean and beautiful. Not a single mark on it. No parasites on the eyes. Wow!
It's so beautiful! 😍
I love how molluscs (including cephalopods) lose and gain limbs with relative ease. I suppose that's the advantage of being made o mostly squishy muscle.
Ah beautiful
Beautiful - thx !
Que lindo e interesante 🦑🦑 sigan así. :p
Those eyes are SOOO creepy! 👻
Also, “Octopotoothus” sounds hilarious. 😂
Thank you this is very interesting .
He or She is adorable. Xxoo👍🤗🥰

Our new overlords.
Thank you Lady and fellow Scientists.
A bit shocking that no diet information is out there after so much studying
Not that hard to believe. We only have so much time to observe the deep sea before we must resurface.
Not to mention we have to find the thing. GPS tags on animals don't work the deeper we go and not all animals can be tagged, especially fragile deep sea ones. Most of the time divers just have to hope they get lucky at finding anything at all, let alone finding the same specimen multiple times.
The ocean is also massive. 3 times the surface area and more than 10 times the volume of all land on the planet, and we still discover new things on land all the time.

Is there anywhere where i can watch livestreams of this?
naming it the octopus squid may have been accurate, but it was still toxic af of them
Is it an octopus or a squid? Yes.

It is wrong
Octopoteuthis, a squid that only has 8 arms and lack the tentacles
Oh, with that posture they almost look like Sea angels!
Give me squid 🐙
No info on the diet at all? Were you unable to catch 1 and do an autopsy on it?
they get distracted by the wiggly things :(
They are very caloric, not good for my diet.

It's considered disrespectful to say that he's not the full squid

yo: comible 👍
lol
octopussy 😂
Thumbs down because you deliberately provoked the squid, causing it to lose an arm 😡
Thumbs up because they did it in the name of science and learned something new. 😊
octopus means 8 legs🤔. pass over some of that weed you smoking for us to try😌💨
it's a squid though, that's why it's unique. it's born with 10 appendages. as it grows, two of those are absorbed back into the body. so it's still a squid, it just appears different. this was explained within the first minute of the video, hope this helps :-)
Watch the video carefully, and read the description. They already explained it.
I think you might need to put down the weed. 😂
All squid have only 8 arms. The extra 2 appendages are tentacles. There is a difference between arms and tentacles.
