Abstract Documenting marine mammal strandings provides important information needed to understand the occurrence and distribution patterns of species. Here, we report on strandings of cetaceans on the Pacific ( n = 11) and Caribbean ( n = 2) coasts of Nicaragua, documented opportunistically from 2014 to 2021. Strandings included three species of baleen whale (blue whale Balaenoptera musculus , Bryde’s whale Balaenoptera edeni , humpback whale Megaptera novaeangliae ) and five species of toothed whale (dwarf sperm whale Kogia sima , Guiana dolphin Sotalia guianensis , pantropical spotted dolphin Stenella attenuata , spinner dolphin Stenella longirostris , Cuvier’s beaked whale Ziphius cavirostris ). These are the first published accounts of blue whales, Bryde’s whales, dwarf sperm whales, and Cuvier’s beaked whales in Nicaraguan waters. Limited resources and the advanced decomposition of animals prevented necropsies in most cases, the identification of the causes of mortality in all cases, and the species identification of two dolphins. Information derived from these stranding events offers new insights into the occurrence of marine mammals on the Pacific and Caribbean coasts of Nicaragua and Central America.
