Scientists have concluded that the male in this seahorse, pipefish, and sea dragon family gives birth in order to sustain the population. Matsushige could finally see what the mating swim was supposed to look like. At 14 inches (36 cm) in length, this is one of the worlds largest species of seahorses. It is highly recommended that you stick with two seahorses of the same sex. To have as little impact as possible on wild seahorse populations, four species of which are endangered, the lab uses pot-bellied seahorses bred in Tasmania for the aquarium trade in their research. Although their eyes and ears are hardly mature at this stage, their nose, mouth, and front limbs are developed enough to climb into their mother's pouch, where they continue growing. Scientists theorize that males in the Syngnathidae family have evolved to carry the babies because it allows the species to create more babies quickly. They tend to live on coral reefs, sea grass beds, estuaries and in mangroves. But it was also helped by the fact that I knew what to look for. After a female octopus lays a clutch of eggs, she quits eating and wastes away; by the time the eggs hatch, she dies. Unlike any other species, male seahorses become pregnant and carry babies (called fry) to term. That means you usually get to dive for around 60 minutes or more, depending on how well you conserve your air. Lets find out. While hundreds of species of fish do change their sex, including, Because of their many colors and their leaf-like appendages, many people think sea dragons are a tropical fish, Matsushige says. Do babies go off milk when they have a cold? Skin grows over the eggs, protecting them until they hatch. Tiny Worms Got Stoned for the Benefit of Science, Scientists Study the Secrets of 2,500-Year-Old Mummified Animals. Instead of growing their babies inside a uterus like human moms do, seahorse dads carry their babies in a pouch." Of those three species, only weedy sea dragons have reproduced in aquariums. This Project Seahorse initiative allows divers to act as citizen scientists.
