They, like annelids and mollusks, have spiral cleavage and trochophore larvae. In its developmental stage, P. peregrina progresses from swimming to crawling in around ten days. Nemerteans often have an Anoplan or Enoplan morphology, with P. peregrina having an Enoplan morphology.
Distribution

Why this record matters
“Paranemertes peregrina” is worth following because a concise public description often conceals a longer documentary argument. Here, Paranemertes, peregrina and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 25, 2026. The linked authority identifier is Q2622437. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
