It seems there are some 15 species of the weedy blackberry from Europe seen across SA.
Tiny green pipefish with spade-shaped snout.
Maybe young juvenile Hypselognathus rostratus?
Saw lots of juvenile pipefish this day.
Hidden among drift algae (Caulocystis sp.) at the surface until it realised it had been seen - it left the drift weed and swam along the surface of the water. Appeared to be in an area of ?longshore current - the current transporting a higher concentration of drift weed parallell to shore heading north with an incoming tide. Approximately 15cm long. The week previous saw some strong westerly winds in the area, so very possible it was blown in to the area rather than resident.
