Description

This red seaweed is Neorhodomela larix, or Black Pine. The clump does look like a miniature forest with thickly growing trees. Each frond is about 4-6" long. It's an abundant seaweed that grows on rocks, visible at a very low tide.

Description

This red seaweed is called "Bladed Red Algae" in Andy Lamb's book, but with no scientific name. I found it growing on a rock at low tide. The larger blade was about 6" long, 4" wide, and the smaller blade about 3" long and 1" wide. It was very supple.
