Adaptations
A streamlined body supports long-distance travel, while throat pleats expand during lunge feeding. Baleen traps small prey as water leaves the mouth, and low-frequency calls can travel through vast areas of ocean.
Behavior and daily life
Blue whales are often seen alone or in small temporary groups. They concentrate where krill is abundant, make deep feeding dives, and use repeated calls that may support communication over long distances.
Conservation
Current profile labelEndangered
Commercial whaling severely reduced blue whale populations. Current pressures include ship strikes, fishing gear, underwater noise, changing prey distribution, and climate effects on productive ocean systems.
A blue whale feeds mainly by lunging through dense krill patches and filtering water through baleen plates.
