This red alga is one of the few plants that can live in the harsh conditions next to the ocean.
The picture's a bit fuzzy at high resolution, sorry, that's my amateur-ness at the camera (shaky-hands). Should have used flash.
- If you know the genus, please provide. Where was this taken, particularly in relation to the marine water line? Does not look like a red alga (Rhodphyta) to me, but I cannot claim to have seen them all. Since I think I see gray lichens on the rock, this cannot be a marine environment and the growth looks more like a lichen than an alga. - Marshman 00:58, 3 February 2006 (UTC)

- Unfortunantely, I don't. If I remember correctly, there was a little sign next to the rock stating that this was red algae (and the info in the first sentence). It was taken on a path to a lighthouse (so it was close to water) but not very close (water unlikely ever reached the place). — Ambush Commander(Talk) 23:57, 17 February 2006 (UTC)
- I suspect it may be another lichen. There are no "red algae" (Rhodophyta) that are terrestrial that I know of. A few species do occur in fresh water and of course most are marine with many that are intertidal. The color of the organism in the photro is just not what I'm used to seeing in the tropics. - Marshman 04:46, 22 February 2006 (UTC)
