Description
The Knysna Seahorse is a critically endangered species endemic to a few estuaries in South Africa. It is a small, slow-moving seahorse that relies on its prehensile tail to cling to seagrass and other holdfasts. Due to its specialized diet and sensitivity to water parameters, it requires expert care in a dedicated aquarium.
