Sagartia ichthystoma
species of cnidarian
Sagartia ichthystoma is a species of sea anemone in the family Sagartiidae, also known as the fish-mouth anemone. The species name refers to the short pointed tentacles round the edge of the disc which resemble the sharp teeth of certain fish.
Description
The base of S. ichthystoma is usually found adhering to rocks or shells and is no wider than the column. This is cylindrical, purplish-red, and about as long as it is wide, covered with corrugations but without warts. It can retract into a nipple-shaped button. The disc is fawn and is slightly concave with an enlarged margin and clearly marked, black radii. The tentacles are translucent white with black and grey bands. They are small and conical and set in three rows which are positioned very close to the margin. The mouth is on a raised mound and the scarlet lips are wrinkled and swollen.
Distribution and habitat
S. ichthystoma is found in the English Channel.
Begin with the source’s own compact description: “Sagartia ichthystoma” is species of cnidarian. The dossier treats that line as a proposition to test through Sagartia, ichthystoma and species, not as a finished interpretation.
Why this record matters
The phrase “species of cnidarian” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q3326576. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
