This photo shows a seahorse while swimming in the water. The seahorse belongs to the genus of the Hippocampus (from greek "Horse" and "Sea monster) and its size can vary from 1 to 35cm in length. The interesting thing about this animal is the mating; in fact, contrarily to most animals, it is the male seahorse duty to take care for the eggs until they hatch. This can last even up to 45 days.
