Aquatic Life Appreciation Thread 🐳 🐠 🐙

This is the 兜蟹 - かぶとがに - Horseshoe crab.
Apart from being living fossils, they play an incredible role in medical applications that I did not know about. These creatures are so valuable, hopefully soon we won’t need to rely on their precious blood anymore.


(Section 4 of the Wiki article)

Harvest for blood

Horseshoe crabs use hemocyanin to carry oxygen through their blood. Because of the copper present in hemocyanin, their blood is blue.[37] Their blood contains amebocytes, which play a similar role to the white blood cells of vertebrates in defending the organism against pathogens. Amebocytes from the blood of L. polyphemus are used to make Limulus amebocyte lysate (LAL), which is used for the detection of bacterial endotoxins in medical applications

I think this one is self explanatory! ^^

So that’s why noble’s blood is blue as well? :eyes: :joy:

Super interesting. I knew about these guys from Endless Ocean, but not that we used their blood for medical science. Poor guys! I’m sure they didn’t expect to be used like that!

As for eating them…I’m still not convinced. :sweat_smile: (even if I like crabs, shrimp and crayfish…but living fossils…>_> )

Fun fact: the Arctic is named after the bears - “arktos” is Ancient Greek for “bear”.

And Antarctica is literally “Place where there are no bears”. That translation sounds much smoother if translated to Japanese imo:

Inspired by the Gliawards current otter-theme I wanted to make a post about Giant River Otters (オオカワウソ).

These otters are different from both the otters found in Europe and the ones in the Arctic. To begin with they are huge (up to 1,7 meters). They are also much more social than other species. They like to hang out in family groups of 3-8 individuals and also hunt in packs! :otter: :otter: :otter: :otter: :otter: :otter:

For more info about this endangered species, see Otterly Fascinating | Science | Smithsonian Magazine

The whole family out for a swim!

Well, that’s obviously an otter from the Arctic so I get their frustration with humankind! :sweat_smile:

(I guess, the giant river otters should be plenty frustrate as well, but they do have that splotshy breast as their signature look. :slight_smile: )

Where I live there’s an abundance of water birds (鸊鷉 or かいつぶり) due to the large number of freshwater lakes, rivers and creeks. I have special fondness for these cute birbs. Not just the big graceful Swans (白鳥), but also the smaller varieties of birds living on water. Several are quite beautiful! ^>^

I didn’t know this thread existed, it’s a very nice surprise :smiling_face_with_three_hearts:

Last week I was able to finally leave my city for a while (after a year or so partially locked down) and I went to the beach. I took some pictures of some of the things that I could spot in the water (I don´t know all of them, but I still find them fascinating).
