Cetacean Stranding Atlas · 10,655 events

Live strandings worldwide.

Where strandings happen events

8,346 place-level events, coloured by outcome. Region/country-only records excluded to avoid centroid clustering.
Survived Died/Killed Euthanized Mixed (mass) Unknown

Stranding hotspots events

The same 8,346 place-level events, clustered into ~65 km localized areas. Bigger circle = more stranding events recorded in that area (i.e. strandings happen there more often); colour = that area's most common outcome. 282 localized areas with 5+ events shown.

Condition & behaviour at stranding events

Standardised signs recorded across 2,822 events that logged observations (multi-label — one animal can show several). Source: injuries & behaviours field.

Highest rescue rate animals

Rescued / recorded fates

    Highest death rate animals

    Died / recorded fates

      Highest euthanasia rate animals

      Euthanized / recorded fates
        Rate = fate / recorded fates (rescued+died+euthanized). Orgs with 10+ events and 50+ recorded fates only.

        Necropsy status reports

        Was a necropsy performed?

        Most common findings reports

        Categorised from 1,800 necropsy reports (multi-label — one report can list several). Grey = administrative / no substantive finding; green "No cause / nothing conclusive" = nothing wrong found.

        Population loss — recorded mortality by species animals

        Animals lost (died + euthanized) per species across all recorded strandings. Population baselines and %-of-population are intentionally omitted for now — this shows absolute recorded losses only. Species that could not be identified are grouped as “Unidentified / unassigned”.
