Seahorse couples, such as this pair of thorny seahorses Hippocampus histrix , greet each other every morning with a unique dance that sometimes involves changing color. The couple promenades and pirouettes together for several minutes before separating for the rest of the day.
They greet each other as a way to confirm the other partner is still alive, reinforce their bond and synchronize their reproductive cycles. Rob Peatling, Flickr. Instead of females, male seahorses carry the developing seahorse embryos in a kangaroo-like pouch. During mating season, the female deposits her eggs into the pouch, and the male fertilizes them. After about two weeks of development, out pop the seahorse fry, ready to swim off and explore the ocean world.
Here is a very pregnant short-snouted seahorse Hippocampus breviceps in Australia. Read ten more things you never knew about seahorses! Seahorses are not just tropical creatures. This long-snouted seahorse Hippocampus guttulatus can be found in UK waters. Until now, only seven pygmy seahorse species had been identified worldwide. One of those species was discovered in Japan, and the remaining six were found in the Coral Triangle in the eastern Pacific.
This newly discovered South African species lives 5, miles away and is the first pygmy seahorse discovered in the Indian Ocean, per a University of Leeds statement. The research team published their findings in the scientific journal ZooKeys this month. Prehensile tail Seahorses all have a prehensile tail. This allows the fish to hold on to objects such as seagrass.
Eyes Like all fishes, the eyes of seahorses can move independently. Because of their placement, it is believed that seahorses have binocular vision. This would help in catching the small crustaceans which make up much of the diet. The reproduction of seahorses is truly remarkable.
The male seahorse has a pouch a marsupium into which the female seahorse lays her eggs. In White's Seahorse, the male fertilises the eggs and cares for them for about three weeks depending upon several factors including the temperature. During this time, he aerates the pouch, and most remarkably of all, nourishes the eggs through a capillary network in the pouch with his own 'placental fluids'.
At the end of the 'pregnancy', the male gives birth to fully formed young seahorses of about 1 cm in length which swim away to care for themselves. The male then 'becomes pregnant' again almost straight away. White's Seahorse is monogamous females and males form permanent pairs and breed from October to April.
