Although the snubfin dolphins share similar external features with the Monodontidae (narwhal), [ 2 ] a genetic study conducted by Arnason and ...
Australian snubfin dolphins have a varied diet, eating a range of fish, shrimp, and cephalopods (squid, cuttlefish and octopus). [9] They are found in small groups of about 2–6, but larger groups (up to 14 individuals) have also been observed. [10] Populations are usually smaller than 150 individuals. [11]

Researchers with NOAA and the University of Miami, among others, worked for eight years studying 147 skulls and 43 spines of stranded bottlenose dolphins. Some specimens were found in South ...
Irrawaddy dolphins are more susceptible to human conflict than most other dolphins that live farther out in the ocean. Drowning in gillnets is the main threat to them throughout their range. Between 1995 and 2001, 38 deaths were reported and 74% died as a result of entanglement in gillnets with large mesh sizes. [ 34 ]
The species has been found in temperate waters, but these occurrences were possibly stray individuals, or associated with warm water events. It generally does not go beyond 50°N or below 50°S . [ 16 ] [ 23 ] It usually inhabits open ocean and deep-water areas, though it may frequent coastal areas near oceanic islands. [ 41 ]
