The Mat, Star Polyps, Suborder Stolonifera

By Bob Fenner

Clavulariid colony in captivity

Mostly large polyps attached by common matter (stolon), attached to the substrate, often in large sheets. Can be overwhelming in growth pushing out other sessile invertebrates. May produce toxic chemicals as well.

Best to keep these highly invasive species isolated on their own "island" rocks...

 

Pachyclavularia violacea. Indo-Pacific. Grow as thick mats that may cover meters of bottom. Stolon has purple reddish color to which all polyps are joined. Photosynthetic. May grow quickly in your aquarium, crowding out desired livestock. Best to confine to individual rocks with a break in-between. Middle of polyps white to greenish, tentacles brownish to greenish. Pinnules on tentacles very small. Close ups and colony in N. Sulawesi at right and below. Note the denuded coral area above the colonies at right. 

Pachyclavularia sp. Queensland, Australia.

Clavularia sp. N. Sulawesi. Polyps 10-20 mm in height, 4-10 mm. in width. Pinnules of tentacles large/conspicuous and long. Western Pacific; Melanesia, Indonesia. N. Sulawesi pix.

Unidentified Clavulariids... there are many. One from N. Sulawesi at right. Gorgeous eh?
