With all that's happening right now, I believe this is a good moment to post this thread(which I wanted to post for a long time now) and hopefully get your minds distracted for a couple minutes, away from the covid19 hysteria outside but also here on ATS, where most of the new threads are about the Corona virus. It also been a while I've seen some new Fragile Earth threads pop up.

So yeah...

Living near the sea and fascinated by it for many years since my childhood, by their inhabitants, the beauty, but also cruelty of the deep waters. Being one of the most powerful force on this planet, witnessing it many times over, I only want to share beauty for now.

Here is a list of my 'top 10' of most interesting and beautiful animals of the sea, in no particular order. It doesn't contain any fish, it's only about slugs, squids and dragons.
I hope you enjoy it and thanks for reading.

The information I added comes from books and numerous websites on the net.
Here are some of the sources used.

1.Comb Jellies
The Bolinopsis infundibulum or Northern comb jelly can be found in the entire North Atlantic Ocean. They have been spotted by remote operated vehicles at depths up to 2km as well at the surface.
The Bolinopsis infundibulum swims with eight longitudinal combs, four long rows and four short rows. These combs consist of plates of transverse rows of hairs that beat in waves downwards, which produces the shimmering effect. These plates are phosphorescent at night.

2.Glaucus atlanticus
Glaucus atlanticus, also called sea swallow, blue dragon or blue angel is a type of sea slug. It uses an air bubble stored in its stomach to keep it afloat, usually on its backside exposing their brightly colored belly as a camouflage against airborne predators while its greyish backside blends in with sea surface, concealing it from predators below, also known as countershading.
Its favorite snack is the Physalia physalis or Portuguese man o' war. When feeding, the Glaucus atlanticus collects the Portuguese man o' war’s venom in special sacs at the end of its ‘fingers’ and can use it later as a way of defend.
The stings from these small creatures are known to be more powerful than from those of the ones it collected it from.

3.Dirona Albolineata
Dirona Albolineata another species of sea slug found in shallow waters along the Pacific coast of N-A and along coastlines of Russia and Japan. Dirona Albolineata are carnivores that feed mostly on snails or small shrimps, crabs and other crustacean.
Just like lizards they can shed their cerata ‘fingers’ when being attacked or in danger to escape their predators.
They can lay up to millions of eggs to ensure that the young make it up to childhood, their life span ranges from 6 months to a year.

4.Glowing sucker octopus
Stauroteuthis syrtensis, also known as the glowing sucker octopus, have been spotted in the deep oceans of the Eastern United States to a depth of 2.5km. It’s a fairly small species growing up to 50cm, eight arms included and is the most bioluminescent octopus.
When stressed or attacked it will inflate its web to defend and scare predators but can also be used to attack its prey. Its arms contain photophores that can flash on and off in a unique pattern. The lights are thought to be used for predatory purposes as well as communication.

5.Weedy Sea dragon
The weedy sea dragon is a popular species of seahorses that are often used as pets in aquariums. They mainly live in the regions of Australia and Tasmania but are also bread throughout the world in captivity.
Although don’t have teeth, these animals are carnivorous. They use their nose or snout to suck up small fish and several types of shrimp. Special muscles in the snout can widen it to capture different sizes of food. Adults can grow to 45cm and live up to 10 years in the wild.

6.Sea Angels, Clione limacina
Sea angles are small translucent, shell-less pelagic sea slugs in the Gymnosomata group.
The Clione limacine or naked sea butterfly is a pteropod that lives at a depth of up to 500m in the colder regions of the Atlantic and Artic Ocean. They are small 20-25mm slugs that uses their two ‘fins’ to move through the water. The slug does not have gills to breath but uses its gelatinous skin to extract oxygen from the water. They can occur in large numbers and is an important food sources for fish and whales, in particular the Balaena mysticetus or bowhead whale.
Norwegian whalers call these species ‘krill’.

7.crown of thorns starfish
Acanthaster planci, coral-eating starfish or crown-of-thorns sea star can be found in coral reefs from the western Indian Ocean to the Red Sea, across the Pacific and the west coast of America.
Adults primarily feeds on coral, they are also called a corallivore. No other animal feeds on coral so efficiently as the Acanthaster planci.
It spends about half of its time on feeding and can crawl at the rate of up to 35cm/min over coral reefs and rubble.

8.Cauliflower jellyfish
Cephea cephea, also known as the crown jellyfish or cauliflower jellyfish and is found in the open waters of the Indo-Pacific and East Atlantic Ocean. It got its name from the cauliflower-looking crown at the top. The Cauliflower Jellyfish is targeted by the Chinese and Japanese fishing industry where it is consumed as delicacy or used for medicinal purposes.

9.Firefly Squid
Watasenia scintillans or firefly squid are small bioluminescent creatures that live in the Western Pacific Ocean, they are often found in deep waters surrounding the coastline of Japan. During the day they mostly live in the deep ocean but during the night they can be seen at the surface and near the shores in search for food. They use their photophores to produce a blue neon like effect which is used to attract prey and to communicate. Several months a year they can be seen in a ‘not to miss light show’ near the shores when they gather to fertilize and drop their eggs.

10.Blanket Octopus
Tremoctopus gracilis, blanket octopus is a large cephalopod which spends
its entire life in the open ocean from the Indian to the Pacific Ocean.
Males and females Tremoctopus are very different from each other, the females(top) can grow up to 2 meters while the male(bottom) not growing larger than a few centimeters.
The webs or blankets of the females can be autotomized (spontaneous casting off of a limb or other body part) potentially acting as a distraction against predators.
During mating the male ruptures a pouch containing a special reproductive arm. He loads this arm with sperm, detaches it and passes it to the female. Once the arm is shed, it is believed the male dies. The detached arm crawls into the gill cavity of the female where it attaches to her gills and is stored until it is required for fertilization.

Thank you!

Some real beauty in nature, the sea holds much we haven't even seen yet. I used to have a 120gal salt water tank, it was full of live rock mostly, a few fish, and various shrimp..when it was feed time, the most amazing critters/worms/wtf would come out of the rock.

Nudibranch


I got attacked by a Crown of Thorns. Actually, it touched it. Damn, those spines are really, really sharp.

Sharp and venomous. You got any side effects from it?

I do quite a bit of scuba diving in the area but never got stung or 'attacked' by anything.
Once I got lucky though, nearly caught myself in a Portuguese man-o-war.

Excellent thread.

Loves me some sea slugs, the shapes and colours of those little guys are amazing.

I particularly love the little blue one, Bolinopsis infundibulum or Northern comb jelly.

They are very small and very beautiful

Indeed the Vampire Squid, another fascinating animal from the deep.
Just look at those eyes man

I believe it is the animal with the biggest eyes in the world, regarding body-eye ration.
