Scientists found that seahorses float with the current, enabling them to gradually creep closer to their target. "Hippocampus" comes from the Ancient Greek hippokampos (ἱππόκαμπος hippókampos), itself from hippos (ἵππος híppos) meaning "horse" and kampos (κάμπος kámpos) meaning "sea monster".

These losses make the ecosystems more vulnerable to other disturbances, such as pollution. Once they've sneaked close enough, they snap their heads toward the animal -- often a tiny crustacean known as a copepod -- in a move called "pivot feeding.". Yep, the seahorse is a shockingly good hunter. It turns out the trick is in the very movements that make us think it is a harmless, cute, kind of clumsy critter. Yes, Seahorses. WATCH the seahorse "pivot" in action, above. Even though these charismatic creatures are banned as trade items, they are still heavily traded in the illicit international markets. They have a unique body morphology with a horse-shaped head, large eyes, curved trunk, and a prehensile tail. (Despite its fearsome name, the vampire squid doesn’t hunt live prey ). I F**kning Love Science writes, "Copepods are speedy little creatures that can zip away from predators after sensing impending danger from movement in the water. It's not sharks. ©2020 Verizon Media. Many marine scientists consider overfishing to be the worst impact humans are having on the oceans. Yes, Seahorses. When we look at a seahorse, we see a creature that barely seems to move -- it seems to more drift, or float with the current. Then with a lightening-fast movement of its head, the prey is in the seahorse's mouth before anyone but the seahorse realizes what just happened.

Male seahorses are the ones who give birth. Seahorses Are The Assassins Of The Sea, New Research Finds. The achievement is even more remarkable, notes Ars Technica, because copepods are incredibly sensitive to movement, fleeing from "even tiny fluid deformations" around them. Several characteristics make seahorses naturally vulnerable to extinction. Jaymi Heimbuch is a writer and photographer specializing in wildlife conservation.

If you picked seahorse, you're dead wrong. Choose the least dangerous animal in the following list: great white shark, seahorse, vampire squid. The shape of their heads also helps them move through the water almost silently; when you combine that with their ability to camouflage into their surroundings thanks to helpful chromatophores within their skin cells, it’s clear that seahorses make apt hunters, proven by a predatory kill rate of around 90%. And who would have thought that such gentle, slow creatures could be so mightily fast when it comes to snagging a meal. Searching for mates can be difficult and risky since seahorses are poor swimmers, found in low densities and rely on camouflage to hide from predators. The problem is that the areas where they take them from are becoming obsolete. Seahorses have clearly figured out how to make the most of their movements. In many regions including China the use of the seahorse for medicine and herbs continues. And fast is right. As stated above, seahorses attach to coral reefs and call it their home.

A seahorse head moves through the water in near "hydrodynamic silence," meaning it barely disturbs the surrounding water and does not startle its prey as it approaches.

Most wild seahorses (here the thorny seahorse Hippocampus histrix) are monogamous and some species mate for life. Despite its ruthless attitude toward copepods, seahorses face innumerable other threats. Part of HuffPost Environment. They are also known to cause serious forms of pollution to the environment and that makes it dangerous for the seahorses to continue living in such harsh conditions. Using advanced imaging techniques, researchers filmed the seahorse's kill shot in action. It's not barracuda. By capturing fish faster than they can reproduce, we are harming entire ecosystems that interact with those species, from the food they eat to the predators that eat them.
