Sea Horse Spike

In human anatomy, it is known that all animals have a brain, but a certain number of them are extremely rare. This can be explained by the fact that, for example, for cockroaches, the main organ of the nervous system - the antennal ganglion - has to be taken as an example. But not only insects and hamadryls have a brain commissure, another very unique mammal also has it - the seahorse with a very strange name.

For example, if you look at pictures of a fish from the finfish family, then its head can be compared to a horse’s muzzle, because in front there is a “nose”, around which there is a part of the shield, which is somewhat similar to a horse’s head. And since he swims using flippers like legs, his head has become very unusual and memorable. In addition, instead of a tongue, there is only one tooth at the end of the flipper’s muzzle, just like on the head of a horse, which also takes part in feeding.

But now you need to understand why it is called a sea horse, because it does not look a bit like any horse. Humans should not be confused with sea horses; these are very different animals, even though they belong to the same order. However, in fact, the horse has nothing to do with sea horses either.

Scientists have long believed that sailing fish that resemble a horse are called ctenophores, which are therefore the only marine and slightly marine fish that have a frenulum that hangs from the base of the upper jaw. Previously, it was believed that animals of the ctenophore order, almost immediately after emerging from their eggs, disperse to different parts of the world and are no longer seen. However, in 2015, scientists conducted a study and found that seahorses mate for the first time (the only time) in their lives, which means that
