Blue Stingrays (Dasyatis chrysonota) are coming every spring in October into the Knysna Lagoon. They can be best viewed at the Knysna Waterfront when the tide is coming in. Then they usually gather under the little jetty close to the Knysna harbour. Sometimes there are groups of up to 50 stingrays.
Previously this species was confused with Dasyatis pastinaca and Dasyatis marmorata, which do not occur in the area. Dasyatis chrysonata occur from Angola to at least St. Lucia, Natal, South Africa, possibly extending to Mozambique and beyond up to about 100 m depth.
