Seaweed
Sargassum is a brown/green algae that ends up as seaweed mats in the middle of the Atlantic Ocean these floating mats are very diverse, and is a habitat for over 250 species of fish and invertebrates. Sometime a piece of the mat breaks loose and floats to the Caribbean where it ends up on our shorelines.
Love this photo! It is so beautiful up close!
Thank you, I get a lucky shot sometimes I am doing a lot of experimenting and totally enjoy it.
