One of several kinds of red seaweed washed up on beach. There were so much seaweed the shore was red.
No interactions present.
Not a lot to go on.
Is it stiff, brittle, cartilaginous? Any evidence of the holdfast? Because it is all criss-crossed I cannot see the branching pattern or tips. It needs spreading out on the sand.
Provisionally possibly Elongate Siphon weed, but could be Purple Claw weed, or a number of others.
