Hi folks.. Could someone please ID these subjects? The first pic is of two unknown light green plants or algae growing between the rocks.

The second pic is some type of red algae growing in the upper right corner of the pic. Some is leafy and some is kind of like wire.

Thanks in advance!!

The first one looks like a species of benthic Sargassum. The secone one is a little too out of focus for me to ID.

Thanks! Lights are off so I can take another tomorrow..

I did look up "benthic Sargassum" and found pictures. You are on point with the ID..
