|Anthocodia (p. Anthocodiae)
||Distal part of a polyp including the
mouth, neck and tentacles, which may or may not be retractable into
||The lower part of the polyp consisting of the gastrodermal
canal where it penetrates the coenenchyme; typically not visible on the
surface of the colony.
||Tree like branching pattern, generally comprising a bare
stalk and polyps arranged on the distal branches and twigs (e.g. Pseudodrifa nigra).
||The arrangement of the sclerites on the head of a polyp.
||A polyp containing eight tentacles and mesenteries; in
dimorphic colonies, they are larger than siphonozooids.
||Inner supporting structure of some octocoral colonies; may or
may not contain sclerites; may be horny and/or calcareous, hollow or solid.
||In Scleraxonia, canals that run longitudinally throughout
colony, separating medulla from cortex.
|Calyx (p. Calyces, adj. Calicular)
||Stiff, projecting portion of the coenenchyme, typically
reinforced by modified sclerites, into which the anthocodia may retract.
||Unbranched colonies with a disk like, spherical or
hemispherical terminus on a narrow stalk, commonly resembling a club or torch
||An elongate sclerite with two girdles of warts or tubercles
at each end (e.g.Leptogorgia hebes); often named by number of tubercles (e.g. Triradiate
|Coenenchyme (adj. Coenenchymal)
||The common colony tissue between the polyps, consisting of
mesoglea penetrated by solenia and gastrodermal canals and containing
||A ring of transversely arranged, bowed anthocodial sclerites
located below the bases of the tentacles; typically associated with points,
forming a ‘collaret and points’ arrangement.
||Ability of an anthocodia to reduce in size without inversion
into the upper part of the anthostele within the coenenchyme, often
accomplished by folding the tentacles inward.
|Cortex (adj. Cortical)
||In Scleraxonia, the layer of coenenchyme surrounding the
||Branching pattern displaying a repeating bifurcation (e.g. Iciligorgia schrammi).
||Unbranched, finger like colony form (e.g. Bellonella
||Having two types of polyps, autozooids and siphonozooids
||Shaped sclerite that displays the fusion of warts into
girdles on one or both sides (e.g.Leptogorgia setacea).
||A spindle like sclerite with a medial constriction and acute
ends (e.g.Viminella barbadensis).
||A sclerite with a medial constriction and blunt ends (e.g. Viminella barbadensis).
||A state in which the end of a flattened branch is rolled
inward, partially fusing and forming a terminal groove (e.g. Iciligorgia schrammi).
||Elongate sclerite with an enlarged end adorned with leaf like
or spinous processes (e.g.Pseudodrifa nigra).
||Resembling a leaf; dorsoventrally compressed and broad (e.g. Renilla reniformis).
||Colonies with a few short, stout branches, often with
clusters of polyps at tips (e.g.Pseudodrifa nigra)
|Loculation (n. loculus, n. p. loculi )
||The presence of spaces between layers of gorgonin in a
holaxonian axis, which may be filled with calcified material, often very
prominent in Plexauridae (loculi refers the pockets or empty spaces between
||Inner supporting structure of a scleraxonian colony,
comprised of sclerites often bound together with various amounts of horny
||Having one type of polyp, autozooids.
||Branching in which a primary polyp gives rise to lateral
daughter or budded polyps (e.g.Telesto sp., Carijoa riisei).
||Enlarged and modified polyp of the pennatulacean colony
bearing autozooids and siphonozooids.
||Often called a stalk, the lower, bare portion of a
pennatulacean colony that anchors in soft substrate.
||Branching in one plane that appears feather like (e.g.Muricea pendula).
||Branching colonies that grow in one plane; fan like.
||A broad, flat, irregularly shaped sclerite (e.g. Scleranthelia rugosa).
||A small flattened sclerite of diverse outline (e.g. Sclerobelemnon theseus).
||Sets of anthocodial sclerites, often bent spindles, forming
eight longitudinal groups at the base of each tentacle; located above the
collaret (if present), forming a ‘collaret and points’
||Flattened expansions bearing secondary polyps in some
pennatulaceans, such as Virgulariidae.
||Raised regions of the coenenchyme into which polyps retract;
not reinforced by modified or specialized sclerites.
||Polyp (in Clavulariidae) giving rise to lateral or daughter
polyps; often the polyp farthest from substrate.
||Fleshy part of a tentacle from which pinnules arise; in
Pennatulacea, the part of the oozooid that produces the other polyps.
||Ability of an anthocodia to fully withdraw into the upper
part of the anthostele within the coenenchyme.
||Microscopic, calcareous structures found in the coenenchyme,
anthocodiae, and sometimes in the axes of octocorals.
||In dimorphic colonies, a polyp with reduced tentacles and
mesenteries; smaller and less conspicuous than autozooids.
||Common sclerite shape displaying an elongate form and
tapering ends (e.g. Gorgoniidae).
||Flat sclerite with peripheral lobes, appearing star like,
sometimes with a protruding knob in the centre (e.g.Bebryce
||An extension of the coenenchyme that traverses the substrate
and connects polyps or colonies, often broad and ribbon like.
