Big-Bellied Seahorses (Hippocampus abdominalis) are one of the largest species of seahorse, reaching a maximum size of 35cm however usually are around 18cm fully stretched out.
These warm water dwellers have a few unique adaptations to help them thrive in their environment. Their skin is made up of tiny interlocking bony plates rather than the scales that you would expect on a fish. They have eyes they can move independently from each other, like a chameleon, to help them spot any predators or prey in the area. Seahorses are not very strong swimmers and so they can often be seen clinging onto their surroundings or each other for stability.
Egg-laying is tasked to the male in seahorse species’, with the female individuals depositing their eggs inside the male pouch. Seahorses can give birth to hundreds of fully-formed babies at a time and can have thousands of babies across a one year period! Sounds like they have a busy life!
