Polyps of the symbiotic colonial zoanthid (Parazoanthus swiftii),
this on a
brown sponge (Agelus sp.). The colonial nature of (Parazoanthus swiftii)
is not so obvious in the above image, but is certainly present. |

| * In the above image, the
brown sponge is probably an (Agelus sp.). The individual
polyps of the symbiotic colonial zoanthid (Parazoanthus swiftii) are well defined, but the colonial nature is less obvious, as it
is in (1).
A common related species is the solitary zoanthid (Parazoanthus parasiticus). This latter zoanthid is greenish in color, and the polyps are isolated. In the waters about the Cayman Islands, it may often be found on the Pink Rope Sponge (Gelloides ramosa) (2). Jackson Bay, Little Cayman Island - Depth 110 feet or 34 meters |
