Night Rockpooling at Marazion!

Midnight Madness at Marazion! Photo copywrite Alan Barker

 What an amazing experience! Despite light drizzle our volunteers only Night Rockpooling session at Marazion causeway was far better than expected! Setting out in our wetsuits and high viz vests and head torches anyone looking on must have wondered what we were up to! Crabs were out and about everywhere and seemed very surprised to be disturbed by crazy humans with torches!
Standing in the shallows our torches attracted hoards of tiny mysid shrimps, prawns and juvenile fish. We were soon joined by inch long adult atlantic cuttlefish. these guys are absolute beauties and although we had seen some on the day time survey we were treated to far more sightings on the night rockpooling!

The survey highlighted once again the incredible diversity of life on this shore and proved that night rockpooling allows you to build a much more full picture of the species present. Particularly species that are more active at night such as fish, crustaceans and cephalopods!
