Knysna Seahorse
Hippocampus capensis
The Knysna /ˈnaɪznə/ seahorse or Cape seahorse (Hippocampus capensis) is a species of fish in the family Syngnathidae. It is endemic to the south coast of South Africa, where it has been found in only three brackish water habitats: the estuary of the Keurbooms River in Plettenberg Bay, the Knysna Lagoon, and the estuarine portion of the Swartvlei system in Sedgefield. The limited range of this seahorse puts it at great risk of extinction.
