A comprehensive molecular phylogeny of Dalytyphloplanida reveals multiple escapes from the marine environment and origins of symbiotic relationships
Van Steenkiste et al., 2013. PLOS ONE 8(3): e59917.
This record is a claim boundary, not a quality badge. Evidence class and species relationship describe what was studied. They do not make the result universal, complete or automatically applicable to a home aquarium.

What was studied
Study shape: Complete 18S and partial 28S rDNA sequences were analysed with maximum-likelihood and Bayesian phylogenetic methods.
Experimental unit: Taxon sequence or specimen represented in the phylogeny
Endpoints: phylogenetic placement, freshwater transition reconstruction, symbiotic-lifestyle reconstruction.
Claim boundary
What it can support: Flatworm lineages and life strategies cannot be inferred from a generic worm-like aquarium silhouette alone.
What it cannot support: The phylogeny does not identify a phone-video organism, demonstrate predation or determine whether an observed flatworm threatens shrimp.
Publication status audit
Canonical DOI outside query result
The record has a canonical DOI but did not appear in the broad Neocaridina query. It requires DOI-specific or alternative-registry status review before any no-update statement.

Correction impact
If this source boundary changes, these are the known downstream consumers. The list distinguishes scientific re-review from generated parity and historical follow-up.
Editorial review required (4)
This curated wording or synthesis must be reconsidered when the source boundary changes. A passing generator test cannot decide the new scientific meaning.

How this record is classified
Morphology or taxonomy: Anatomy, specimen identification or taxonomic relationships were studied with stated methods. A trade name or photograph cannot replace those methods.
Adjacent biological evidence: The source studied another organism or a broad biological group. The inference to Neocaridina must remain explicit.
Topics: Species and taxonomy, Health
Critically appraise this source without a score
These questions fit this record's morphology or taxonomy role. They are prompts, not automatic judgments. Open the original source to answer them.
- Identity and provenance: How were the organism, population, stock and life stage identified and sourced? A published name or seller label can hide a taxonomic, population or life-stage transfer.
- Independent unit: What unit was independently assigned or sampled, and how many units support each comparison? Animal counts do not create independent replication when animals share a vessel, site, family or treatment history.
- Comparison and context: What was the actual comparator, allocation process, environment, duration and material condition? A result has meaning only against the comparison and conditions that produced it.
- Endpoint and measurement: Which endpoint was measured, with what method, unit, timing, resolution and decision rule? One endpoint cannot silently become survival, welfare, diagnosis, reproduction or long-term population performance.
- Denominators and missingness: Are starting counts, exclusions, losses, missing observations and analysis denominators reconciled? Unreported or changing denominators can alter the apparent direction, precision and applicability of a result.
- Transfer boundary: What is the nearest tempting aquarium claim that this source design cannot establish? Direct evidence can still be narrow, and adjacent evidence can be useful only while the inference remains visible.
- Examined material: Which specimens, localities, sexes, stages, types or sequence accessions were actually examined? A diagnosis applies to examined material and methods, not automatically to a trade-line photograph.
- Diagnostic characters: Which characters or loci distinguish the taxon, and were alternatives explicitly compared? Color alone may be variable, convergent or unrelated to the diagnostic character.
- Name history: Were synonyms, historical combinations, type material and later revisions checked? An older title can describe a population that later work placed in another taxon.
- Consumer identification limit: Can the required character or method be observed reliably in an ordinary live-animal image? A valid taxonomic method may still be unavailable to a keeper examining one photograph.
