Structure and ultrastructure of the endodermal region of the alimentary tract in the freshwater shrimp Neocaridina heteropoda
Sonakowska et al., 2015. PLOS ONE 10(5): e0126900.
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: Digestive structures were examined with microtomography, light microscopy and electron microscopy.
Experimental unit: Prepared animal and tissue specimen
Endpoints: intestine structure, hepatopancreas structure, cell ultrastructure.
Claim boundary
What it can support: Method-confirmed internal digestive anatomy in the source taxon.
What it cannot support: An ordinary tank photograph cannot identify these internal organs, function or disease from colour alone.
Publication status audit
Matched in dated Crossref query
The canonical DOI appeared in the dated broad query and carried no registered update in that response. This is a metadata observation, not proof that the work has never changed.
Metadata snapshot reviewed 2026-08-12. Inspect the method, unmatched queue and limitations.
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 (6)
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.
Direct Neocaridina evidence: The source measured animals named within Neocaridina. Direct still does not mean universal or sufficient.
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.
