Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.
