This tangled clump washed up on the beach is a brown algae commonly called strapweed,
Phyllospora comosa.
There seemed to be quite a lots of this on the beach this evening so I used the opportunity to create some foreground interest to a familiar theme. As is also a familiar theme is washing the seawater soaked tripod after the shot.
