The melon-headed whale is a robust oceanic dolphin with a tapering rounded head, no beak, pointed flippers and a tall curved dorsal fin. Its dark face mask and dorsal cape can be subtle at sea. Adults reach about 2.7 m and 209 kg (NOAA Fisheries).
It lives mainly in deep tropical waters and often forms highly social groups of hundreds, sometimes mixing with Fraser's, spinner and other dolphins. Groups tend to rest in the morning, socialize later and feed at night on fish, squid, cuttlefish and shrimp. Gestation is about twelve months (NOAA Fisheries). It is Nationally Least Concern (Thailand Red Data 2025).
