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.

  • published global assessment
Vertical position is the IUCN risk order, not a measured quantity: the gaps between categories are equal on the page and not in nature. The dashed step crosses the 2001 revision of the Red List criteria: the category codes on either side match, the criteria behind them do not, so the step is shown and not measured.

Category movement since listing: deteriorated. Baseline EN in 2010, latest CR in 2022, an observed window of 12 years. This is the direction of change between two Red List categories. It is not a status trajectory and it is not an effectiveness result, because no genuine-change flag exists in the source and no counterfactual is available. How this is defined

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

18 seizure records name this species. Matching is on the taxon the source reported, case aside, and each record below shows the reported name, so a match that is not literal can be seen for what it is. 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.
