🔹Tsunami in Greenland 😨😱🌊🌊
A video shared on social media shows fishermen off the west coast of Greenland rushing to escape a tsunami . Men start moving when they realize that the strength of the water is gradually increasing . The recording, published last few week on Licet Studios channel, shows the desperation of fishermen, who run out in an attempt to escape the phenomenon. According to the post, no one was hurt. According to Licet Studios, the "tsunami" was caused by a giant landslide that occurred about 30 km near the site. It fell about 1 km into the fjord and created a mega-tsunami that was initially 100 meters high. It was the only recorded mega-tsunami so far ".

This is definitely the biggest Gastrotrich I’ve found yet!! It was the first time I could see his little eyes 🥺 and I always love me a small round mouth 😯 I’ve decided to call this cute one Juliette. Doesn’t mean you’ve got a hairy belly that you’re a guy 🙄 c’mon!!
Juliette is colorless, has a flat belly and a hairy body! The flattened tummy is covered in rows of small cilia allowing Juliette to move and glide on different surfaces. Juliettes are found in semiterrestrial and freshwater ecosystems all over the world in surface sediments and among vegetation. They’re especially easy to find in lakes, ponds and wetlands.
Gastrotrichs are still poorly known even if they’re one of the most abundant group of freshwater invertebrates with rotifers and nematodes. They’re multicellular organisms and have around 1000 cells. They possess a digestive system with a mouth and an anus, a muscular system, a small brain with two lobes and a reproductive system. They usually feed on algae, bacteria, protozoans, detritus and small inorganic food particles.
Juliettes are super tough little animals, they can survive months without oxygen at the bottom of ponds and lakes! Soooo not only tardigrades are tough animals 👀

It’s hard to believe these alien-like creature actually exist! 👽
These fascinating invertebrates are known as the Blue Button or Porpita porpita (back) and the Blue Dragon or Glaucilla marginata (front).
This ciliate protozoan is from the Trachelius genus and reminds me of the moon, full of craters of various sizes 🌙
These crater structures are actually called contractile vacuoles and their role is to regulate the osmotic pressure inside the cell. Imagine you’re on a boat with holes in it and you tried to keep the water out by filling buckets! That’s pretty much the role of those contractile vacuoles, they’re the buckets of this tiny Trachelius ship 😄
Trachelius is a predator and carnivorous little boi and loves to feed on Peritrich ciliates like Vorticella but also likes a good Rotifer or even some algae! If you’ve seen my other videos of Dileptus, you may have noticed that Trachelius has the same elephant trunk structure near its mouth. This part of the cell is called the proboscis and is used to sense the environment and potential preys.
It has been observed before that when Trachelius is trapped under the cover slip (the small piece of glass we put on top of the sample) it tends to eject some body parts or cellular content. When I started following Trachelius around, it lost its proboscis and got me really confused with what this little buddy could be 😂 at last, I found others like him in the sample and was able to identify him 😇
That’s all for today folks!! 💜💜
