Dolphins are primarily carnivorous and their diet largely consists of various species of fish and squid. The specific type of prey can vary greatly depending on the dolphin's geographic location, species, and local ecosystem. For example, bottlenose dolphins typically consume fish like herring, cod, and mackerel, as well as cuttlefish and squid. As dolphins are integral parts of the marine ecosystem and their dietary habits provide valuable insights into the health of oceans, dolphin tracking and their conservation is crucial.
