One of 43: each square a species, coloured by its latest global Red List category, this one ringed. Stejneger's Beaked Whale is among the cetaceans.

In summary derived

Mesoplodon stejnegeri, Stejneger's Beaked Whale, is placed in family Ziphiidae, order Cetacea, class Mammalia. It was first listed in Appendix II in 1979. The earliest CITES listing row the corpus holds for it is Appendix II, dated 2003, a later entry than the 1979 listing. The corpus records 1 dated listing row in total.

Its latest global Red List assessment is Near Threatened, published 2020. It carries 2 earlier global assessments on the current scale and 1 on a scale that was superseded before the current categories and cannot be compared with them.

The corpus holds 11 exporter-reported CITES trade records for it, from 1997 to 2019, reported across 1 unit dimension. The most frequently recorded term is specimens (11 records). The corpus holds no NAMMCO catch records for it. No seizure record in the corpus is attributed to it.

Trade derived

CITES Trade Database v2025.1, extracted 13 June 2025.

There is no single trade total

Quantities are reported per unit dimension, per traded term, and per reporting side. These are not additive: kilograms and individual animals have no common unit, a live animal is not a carving, and an importer report and an exporter report are two accounts of one shipment rather than two shipments.

Figures below are exporter-reported.

Trade over time

Peak 2 records in 1997. Trade records per year, exporter-reported, every term and unit counted as records, not quantities.

Peak 27 specimens in 2019. Quantity of specimens, the term with most records (11), in specimens, exporter-reported. Other terms are in the tables below, each in its own unit.

count measured in specimens

11 of 11 records carry a quantity in specimens. CITES leaves the unit blank to mean a count of the term.

CITES listings curated

CoP decisions, cross-checked against the appendix reported on trade records.

First listed on 1979-06-28, in Appendix II, from the CITES listing history. The table below holds the species' current listing entries, which begin later; earlier coverage is often under a higher taxon.

Date	Appendix	Annotation	Status
2003-02-13	II	[ORDER listing Cetacea spp.] Included in Appendix II, except for the species included in Appendix I. A zero annual export quota has been established for live specimens from the Black Sea population of Tursiops truncatus removed from the wild and traded for primarily commercial purposes.	earliest current entry

IUCN Red List derived

Assessment history. Scope is always stated: a regional assessment is not the species status.

This history crosses a criteria revision

Categories from before 2001 come from earlier Red List systems. Three kinds are kept apart.

LR/lc and LR/nt are the modern LC and NT under their old names, so they are plotted as those categories and the line runs through them: nothing changed but the wording.

LR/cd was discontinued with no successor. This project reads it as Near Threatened, following a published crosswalk between the old and new Red List systems, and the chart marks such a point hollow and names both codes, because placing a category is not the same as finding it published.

The pre-1994 codes (E, V, K, T and the rest) are not on the risk order at all, so they sit below the axis and the line breaks across them. A category change across a criteria revision is not a change in extinction risk, and none of these is scored as a movement: the ledger refuses every one of them at gate 3.

published global assessment
not on this scale (below the axis)

Vertical position is the IUCN risk order, not a measured quantity: the gaps between categories are equal on the page and not in nature. Anything that is not one of the nine modern categories carries no position on that order — Data Deficient, a superseded category, or a record that no assessment was made — so it sits below the axis and the line breaks across it rather than joining through. Each point names which it is.

Category movement since listing: not scored. Gate 3: the baseline category K comes from a pre-2001 Red List system and is not on the modern ordinal scale. Insufficiently Known (pre-1994; not a risk category). How this is defined and why some species are not scored

Year	Category	Meaning	Scope	Status
2020	NT	Near Threatened	Global	current for this scope
2008	DD	Data Deficient	Global

1994	K	Insufficiently Known (pre-1994; not a risk category)	Global

Reported catch derived

NAMMCO catch exports dated 11 June 2025. A reported zero is stored as zero, distinct from an unknown.

No NAMMCO catch records for this species. NAMMCO reports on a subset of marine mammals, so an absence here is expected for most species and does not mean no catch occurred.

Illegal trade seizures derived

Seizure records whose reported taxon resolves to this species.

What the seizure source records

No seizure in the compilation names this species. Matching is on the taxon the source reported, case aside. Across the whole compilation, 225 of 919 rows match one of the 43 species and the rest name other taxa.

Quantities are unitless. The source gives no date or place, so the table shows the product and the reported taxon.

No seizure records attributed to this species.

References withheld

Machine-proposed bindings. Shown only where an expert has signed the profile and the binding is live.

No references are recorded for this species: none is shown, and none was machine-proposed for review.
