Uniqueness of the seahorse swimming in an upright position

The body of seahorses is stuffed into large bony armor plates and rectangular. Its swimming form is very different from the other fish. Adopt an upright position, driving its dorsal fin. They have no anal fin, but a tail elongated spiral is wound and allows them to hold on to stem seals.

Species

At the current time is proposed for classifying more than 120 species of this curious fish, but since many of them were actually the same species have been taken as such, establishing currently 32 species worldwide, though are expected some complex changes when certain species are more carefully reviewed. Part of this difficulty, to carry out its classification, lies in the fact that they can change color or develop on your skin filaments to blend better in your environment. Neither is well understood as these animals can vary in their development, size and shape or how it is determined by habitat, geographic location, environmental temperature and / or age. The confusion is such that it leads many to assume that scientists have found a new species, when really what they are doing is to rename one as previously described.

Size

Its size in adults, come in various sizes, from the smallest Hippocampus minotaur that was discovered in Australia and measures 15mm in length, to the huge Hippocampus in gens that exceeds 29cm in length.

Habitat

Globally distributed in both tropical and temperate waters in the areas being Indo-West Pacific and Atlantic. They live among the algae, mangroves and coral. Degradation and destruction of their habitats are increasing. Marine vegetation is dredged or covered to make stuffed into the sea; mangroves are being cut and flooded with fresh water.

Food

Seahorses are predator’s voracisimos. His eyes, which have independent mobility between them, help them recognize their favorite snack, tiny crustaceans which are part of the zooplankton. When the dam gets its power is sucked through their bony snout extremely fast through a stroke of his head. Swallow whole their prey in the absence of teeth, and are forced to consume large amounts of food to compensate for their rapid and inefficient digestion to have no stomach.

Reproduction

It is the only of the genera of animals where they become pregnant is the male. The female uses her ovipositor to insert eggs mature within the male’s brood pouch, within which are fertilized.

Oxygen diffuses through the capillaries of the tissue lining the ovules. Hormones help to create a placental fluid that bathes a small part of the egg tissue protruding from the bag. The environment created by the fluid in the bag is altered during pregnancy from being similar to body fluids to resemble the surrounding seawater, presumably to reduce the stress in the offspring at the time of delivery. Pregnancy lasts 10 days and 6 weeks, depending on the species and temperature of seawater. After this period, the male goes into labor and, through contraction and pumping inside your bag to the outside for several hours, ejects the young. These are miniature replicas of their parents; about seven to eleven millimeters long, and are able to fend for themselves immediately after birth. Are totally independent and not return to the bag after birth.
