Atlanta brunnea
species of mollusc
Atlanta brunnea is a species of sea snail, a holoplanktonic marine gastropod mollusk in the family Atlantidae.
Description
Atlanta brunnea is a small species (shell diameter to 2.0 mm) that is darkly pigmented (brown to reddish-and golden-brown). The keel is tall and colorless, and inserts between the last and penultimate shell whorls in animals larger than 1.5 mm. The spire is tall and conical, consisting of 4 whorls and possessing a complex pattern of spiral sculpture that ends on the protoconch and is replaced by spiral rows of small punctae on the teleoconch. Coloration ranges from brown to amber and reddish brown.
Juveniles of this species are easily recognised by their shape and ornament. The protoconch is rather high conical and has 3½ - 3¾ whorls, slowly increasing in diameter. On the first whorl, in front of the nucleus, an ornament is seen of some nine or ten irregular spirals. Two stronger spirals from the second whorl on delimit a subsutural zone and the base of the shell. On these spirals the whorl profile is slightly angular.
“Atlanta brunnea” enters the record as species of mollusc. Crown Archives preserves that source wording while asking what Atlanta, brunnea and species can confirm, complicate or overturn.
Why this record matters
“Atlanta brunnea” is worth following because a concise public description often conceals a longer documentary argument. Here, Atlanta, brunnea and species provides the most credible route into that argument.
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 28, 2026. The linked authority identifier is Q3176642. 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.
