Heteromysis
genus of mysids
Heteromysis (from Greek heteros meaning ‘different’, and mysis, a genus name Mysis) is a genus of marine mysid crustaceans (opossum shrimps) from the family Mysidae, associated with various shallow-water invertebrates. The name describes differentiation of its pereiopods (thoracic appendages) as possible adaptation to commensal life-style. Heteromysis is one of the largest mysid genera, containing more than 100 species. The genus is distributed globally, but predominantly in tropical and subtropical waters.
Description
The body is rather moderately robust. Telson
trapezoidal, apically with cleft. Eyes with well developed cornea.
Pereiopod 1 carpopropodus always in possession of some either smooth or
modified spiniform setae. Pereopod 2 carpopropodus multisegmented. Uropodal endopod with spiniform setae on its inner margin.
“Heteromysis” enters the record as genus of mysids. Crown Archives preserves that source wording while asking what Heteromysis, genus and mysids can confirm, complicate or overturn.
Why this record matters
“Heteromysis” is worth following because a concise public description often conceals a longer documentary argument. Here, Heteromysis, genus and mysids 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 18, 2026. The linked authority identifier is Q4511010. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
How to read it
