Sometimes I like to revel in the oldest prehistoric animals, put aside the great saurian to which we are accustomed to seeing and who are better known and delve me at the beginning of life, dive into the origin of evolution. When existing evolutionary branches were more diverse and where we find primitive animals and, in a way, awaken our imagination.
The Jaekelopterus is a good example. If we read a book of science fiction, books describing other worlds and invented creatures living in it, we could find a Jaekeloptero swimming in its waters.
Brief description of the animal: this prehistoric animal, it is the order of the eurypterids, namely Scorpions sea. Among all species of these ancient scorpions, the bigger the Jaekelopterus.
Its dimensions are tremendous, we are talking about more than 2.5 meters long (just imagine a scorpion 2.5 meters long (82 ft.) coming through the door of the room by going directly to you ... scares eh?) So great was that it is considered a predator who held one of the highest positions in the food chain....
How they hunted?
Together with those dimensions, hunting is the most amazing of all. The Jaekelopterus had two pincers of no less than about 50 cm (16 ft.) in two of its appendages that could extend to grab its prey tightly. Close and personal with a rapid expansion of its appendices remained motionless at predated while it was eating it.
This last detail makes us think one thing. We have said that could reach 2.5 meters long (82 ft.). But when his paws and claws extended, the length of this increased to one meter, reaching measuring 3.5 meters long (115 ft.).
However, no one seems to ensure that it was a true predator, and it seems that this animal could get most of their food from the carrion of other dead animals.
As is understood by the name, this animal was aquatic. But it is thought that did not live in seas, but in swamps, rivers, etc ...
He lived in the Devonian, 390 million years ago, when many of the mainland were still together.
Finally, these animals are a bit in no man's land. It is not known exactly whether they are really related to scorpions, with arachnids or the horseshoe crab.
