- n. A pennatulaceous polyp, especially of the family Pennatulidæ; a sea-feather. See cut under Alcyonaria.
Sorry, no etymologies found.
The fleshy appendage at the lower extremity of the sea-pen (described at Bahia Blanca) also forms part of the zoophyte, as a whole, in the same manner as the roots of a tree form part of the whole tree, and not of the individual leaf or flower-buds.
I will only mention one other animal, a zoophyte (I believe Virgularia Patagonica), a kind of sea-pen.
Every sea-pen is glorious in its light, in fact, nearly every eight-armed Alcyonarian is thus resplendent, and the social Pyrosoma, bulky and a free swimmer, glows like a bar of hot metal with a white and green radiance. "
