The bottlenose dolphin is the most well-studied cetacean and a flagship species for marine intelligence research. Found in warm and temperate oceans worldwide, these highly social mammals live in dynamic fission-fusion groups called pods that shift constantly in composition. Their cultural transmission of behaviors, use of signature calls, and tool use have cemented their status as among the most cognitively sophisticated non-human animals on Earth.

💡 Fun Facts
01
Bottlenose dolphins sleep with one brain hemisphere at a time — a phenomenon called unihemispheric slow-wave sleep — keeping one eye open and alert for danger.
02
Each individual dolphin develops a unique signature whistle within the first few months of life that functions as a personal name recognized by other dolphins.
03
Dolphins in Shark Bay, Australia, have been observed using marine sponges as tools to protect their rostrums while probing rocky seafloor for fish.
04
Their echolocation system produces clicks focused by a fatty melon in the forehead and can resolve objects as small as a golf ball at 70 meters.
05
Bottlenose dolphins have been documented teaching their calves to fish, passing down culturally learned foraging techniques across generations.
