From the deep -- Researchers find new species of sea anemone

...ength of A. pearseae's tentacles ?a characteristic common to this group of about seven sea anemones. "We tend to differentiate Anthosactis species from other groups of sea anemones by a variety of traits, rather than any one unique attribute," Daly said.
