Limatula hodgsoni
species of mollusc
Limatula hodgsoni is a species of bivalve mollusc in the family Limidae, the file shells or file clams. It is native to the seas around Antarctica.
Description
Limatula hodgsoni grows to a length of 27 mm (1.1 in), a height of 35 mm (1.4 in) and a diameter of 20 mm (0.8 in). The shell is white, oblong, thin, narrow above and somewhat convex; the posterior side is less curved than the anterior. The umbones are central and the ligament area is narrow and diamond-shaped. The valves are sculpted by 30 to 35 squamate ribs separated by grooves slightly narrower than the ribs. The ribs are finely marked by the annual growth lines.
Distribution
Limatula hodgsoni is found on the seabed of the waters around Antarctica at depths down to at least 769 m (2,500 ft). It is very common in the zone deeper than 33 m (110 ft) which is the lower limit for anchor ice formation. In some areas, this zone is characterised by a layer of sponge spicules and dead mollusc shells a metre or more thick, overgrown by living sponges.
The public source identifies “Limatula hodgsoni” as species of mollusc. This brief keeps that definition visible, then builds a research path around Limatula, hodgsoni and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Limatula hodgsoni”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 20, 2026. The linked authority identifier is Q13763375. 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.
