Just watched this on EVnautilus (one of my favorite youtube channels) on deep sea corals, wondering if it would ever be possible to keep these in an aquarium..... I think it was this video where one of them were over 2000 years old. Very slow growing...
post anything related to deep sea critters here,anything that spends time in very deep water (even temporarily). Counts.
