DS256 4 Posted December 1, 2019 Not exactly underwater but close. I have some shots of plant (?) growth along the ironshore of Grand Cayman. There is very little tide so I assume these are exposed all the time except for wave action. So looking for help in two areas: Anyone have any idea what this is? How do you classify these so I can look them up? Obviously not something you'd find in Humann & DeLoach. Thanks Share this post Link to post Share on other sites
bmorescuba 20 Posted December 2, 2019 I would classify them as intertidal algae and search for that. One might be Padina pavonica or close (https://en.wikipedia.org/wiki/Padina_pavonica) The other sure looks like some type of Red Algae (Amphiroa), but there are so many varieties... Good luck Share this post Link to post Share on other sites
DS256 4 Posted December 2, 2019 Thanks bmorescuba. Your link provided an additional insight. I believe these are in the 'Littoral zone' of the shore. I was incorrect in the Cayman tides. They exist so there is a high/low water mark. Share this post Link to post Share on other sites
