Neomysis integer
species of mysid
Neomysis integer is a species of opossum shrimp found in shallow marine bays and estuaries of Europe, with a transparent greenish or brownish body and a large cephalothorax. It is found in very shallow water in both high and low-salinity habitats. It is a filter feeder and the female broods her eggs in a brood pouch beneath her cephalothorax.
Description
Neomysis integer is a slender opossum shrimp growing to a maximum length of about 17 mm (0.7 in). The head has a pair of large, stalked eyes and two pairs of antennae, both of which are biramous (branched into two parts). The exopod (the outermost branch) of the second antenna forms an elongated scale with bristles round its edges and extends forward into a sharp point. The thorax has eight segments each bearing a pair of biramous limbs, the outer branches of which have a feathery appearance. The head and first six segments of the thorax are covered by a protective carapace which extends forward in a triangular plate with a depressed centre between the eyes. The abdomen bears short limbs and the last segment bears larger, flattened biramous limbs which form a tail fan. The telson (the last abdominal segment between the tail fan) is not forked, a fact emphasised by the specific name "integer".
“Neomysis integer” enters the record as species of mysid. Crown Archives preserves that source wording while asking what Neomysis, integer and species can confirm, complicate or overturn.
Why this record matters
“Neomysis integer” is worth following because a concise public description often conceals a longer documentary argument. Here, Neomysis, integer and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 20, 2025. The linked authority identifier is Q3858315. 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.
