How Much Do Dolphins Weigh?
"Dolphin" refers to a broad group of over 40 species, and body weight varies dramatically across them. There is no single answer — size depends heavily on the species, as well as the *** and age of the individual animal.
Weight by Species
- Hector's dolphin — One of the world's smallest dolphins, native to New Zealand. Adults typically weigh around 40–60 kg (88–132 lb).
- Common bottlenose dolphin (Tursiops truncatus) — The most familiar and widely studied species. Adults generally range from 150 to 650 kg (330–1,430 lb), with males tending to be significantly heavier than females.
