Fin-tastic Facts About The Lined Seahorse For Kids

Lined seahorse facts that are interesting and amusing for everyone.

The lined seahorses are US native species of seahorses that range from Nova, Scotia, Canada, Northern Gulf of Mexico all the way to Venezuela and Panama. They are also known as the spotted or Northern seahorse. Many hobbyists consider it the most attractive of all seahorses. They are the only seahorse that lives in Chesapeake bay, and they are poor swimmers who rely on their camouflage ability to hide from predators. The lined seahorses prey by changing colors to match its surrounding, and since they can't swim and chase their food, they suck it up through their snouts like a vacuum.

The lined seahorse (Hippocampus erectus) are a large species of seahorses, and like any other seahorse, the male carries the young to incubate them in his brood pouch. The average age at which the male and female reproductivity maturity begins is 273 days. These aquatic species swim weakly, and when moving from one perch to another, they are so slow that it would take about five minutes to cross a bathtub. Basically, they float, not swim, and due to this many of them are unable to escape from predators quickly, or migrate when the water temperature increases.

Male seahorses have an incubation pocket, which is similar to the pouch of a marsupial mammal, on its lower tail with an opening that can be closed. During the courtship, the female sea horse spray between 250-1000 eggs into the male brood pouch for incubation for 20-21 days. Even after hatching, the free embryos are carried in the pouch until they are capable of swimming. When it is time for birth, the male holds fast to an object or plant step while bending rapidly, backward and forward where the pouch opens and baby seahorse pops out, and the jerking motions of the male continue until the pouch is emptied.
