- n. A group of Coelenterata, including the medusas or jellyfishes, and hydroids, called sea nettles from their sting.
Further, the substance of some of these intermediate creatures is fleshlike, as is the case with the so-called tethya (or ascidians) and the acalephae (or sea-anemones); but the sponge is in every respect like a vegetable.
He is a type of a class, and I take him to be one of the elementary forms of animal life, like the acalephae.
The acalephae were not so numerous as they had been further to the north, but we saw more and larger medusae than I had ever before remarked.
It indeed appeared as if the acalephae diminished and the medusae increased in number after passing the 36th degree of south latitude.
