How to restore oyster colonies with the help of underwater “music”.

A group of marine biologists from the University of Adelaide, cited by the Freshscience portal, claim to have found a winning solution to restoring oyster colonies that have been plagued by their oyster heads, or rather their shells, for more than a century. The fact that it was about pollution, intensive fishing, global warming, no longer matters. Of course, they don’t have much left, and they join the dodo bird and the mammoth on the list of extinct species that cannot be brought back to life. Oysters, not biologists. And this has had a detrimental effect on marine ecosystems, because oysters and other types of shellfish are known to have a very well-established role, which is to maintain water quality through filtration, to serve as food for other animals, and so on.

And, according to the biologists mentioned above, the plan is to return oysters to where they belong with the help of underwater ecological “music”. The trick is that it is not music in the literal sense of the word, but recordings of the sounds made by shrimp. I’m referring to all the popping, splashing, and other sounds that shrimp make as they run and play in the water. It is said that young molluscs perceive the wind at such sounds, create real underwater “highways” and are guided by noises to establish colonies.

This is how our heart returns to its place. It’s not that we’re sure they’re going to blow up the market with their song, but rather that they haven’t found a way to lure clams into the water with real music. That’s all it takes for clam colonies to find that some can forego an old-fashioned beach party, only to have their oysters jump straight onto a plate of sliced ​​lemons and slices of warm bread, just fine to eat in a bowl of garlic sauce.

The cutest crocodile lived in Australia

Around 1985, paleontologists from the University of New South Wales discovered a never-before-seen back fragment of a crocodile’s skull. It was in northern Queensland, in Miocene sedimentary deposits, and they estimated the age of this skull to be about 13.5 million years. So far so good.

Recently, other paleontologists have picked up on the fossils in question and conducted what they say is the most complex analysis ever conducted on a prehistoric crocodile. They found that the specimen was sexually mature and did not exceed 70-90 centimeters in length with a maximum weight of 1-2 kilograms, without bones. This makes it the smallest crocodile that ever existed. Moreover, it also had three ridges on the top of its head. A cute animal to pet and play with all day long, if he didn’t have the bad urge to disappear. Oh look, it also has a cute name, Trilophosuchus rackhami, to make it easy to remember.

Experts from Australia also say that this little fluff resembled other extinct species, from Africa and South America, and not the current species, to which it is much closer in time. Baska, he preferred forests and less water. How, if there were people of his time, the greatest danger was only to accidentally step on him through the shoots. It is possible that other large animals did it, see, so it disappeared.

Don’t upset the reptiles, they get excited too!

With reptiles, it is more difficult to determine whether they have feelings or not. How cold-blooded they are, those crazy fixed eyes… it’s hard, you can’t understand what’s going on in their heads. It’s also what some biologists from the Universities of Adelaide and Melbourne say today seems to be Australia’s Science Day. But they decided to solve this urgent problem for humanity once and for all.

For this noble purpose, they selected several species of snakes, lizards and turtles and subjected them to various tests. It turns out that reptiles have emotions.

For example, if they start to explore their surroundings or observe very carefully what is happening around them, it means that they are happy. Conversely, if their eyes or nose run, it means that they are stressed. Very revealing, remember. In conclusion, if there is mold on your iguana, python, lizard, or anything else in your home, do the right thing and fix the problem, you just pissed off a loving animal in the house!

Sensational paleontological discovery in South Africa

In the specialized journal Palaeogeography, Palaeoclimatology, Palaeoecology, a unique discovery of paleontologists, if not more, was published by an international group of researchers who just happened to be lucky in South Africa. More precisely, these people discovered a small herd of leafosaurs, squeezed out by sediments and starving, but in an otherwise excellent condition, thanks to which it was possible to determine for the first time how these animals had skin.

Now let’s explain a little about what listrosaurs are! During the most devastating episode in the history of life, the mass extinction of life forms at the end of the Permian period, about 252 million years ago, about 80% of life forms on Earth disappeared. Listrosaurs were among the few survivors, that is, among the common ancestors of modern reptiles and mammals. They were small animals, about the size of fatter cats, looking like a hippopotamus, with a parrot-like beak and a few walrus tusks. Beauty!

Lystrosaurs were so successful in the completely new world they found themselves in that they accounted for nearly 90% of terrestrial vertebrate life. The success was immediate, because listrosaurs began to grow in size, became dependent on the environment in which they lived, and when the environment changed, they became extinct. So, most likely, a genetic dead end. Returning to the discovery of the mentioned paleontologists, we can say that more than 170 fossils of at least eight individuals have been identified.

It looks like they all starved to death, which again shows what I said above. Their environment was changing and they could not change with it. It is also interesting that for the first time it was possible to establish that the skin of these animals is not similar to the skin of crocodiles, as was initially assumed, but similar to the skin of hippopotamuses. We don’t know how this news will help you, but if you like paleontology, you will definitely be interested in it.
