Basking Shark Cetorhinus maximusrinus

The basking shark is the second largest fish in our oceans - its relative the whale shark being the biggest. Despite their size, basking sharks only feed on zooplankton which they filter out of the water, swimming slowly back and forth with their enormous mouths wide open. Image: Green Fire Productions (iNaturalist).
