The striped dolphin (Stenella coeruleoalba) is a dolphin found in temperate and tropical waters of all the world's oceans. It is a member of the oceanic dolphin family, Delphinidae. The striped dolphin, also known as the euphrosyne dolphin, is one of five species traditionally included in the genus Stenella; however, recent genetic work by LeDuc et al. (1999) indicates Stenella, as traditionally conceived, is not a natural group. According to that study, the closest relatives of the striped dolphin are the Clymene dolphin, the common dolphins, the Atlantic spotted dolphin, and Indo-Pacific bottlenose dolphin, which was formerly considered a subspecies of the common bottlenose dolphin. The striped dolphin was described by Prussian physician and botanist Franz Meyen in 1833.
The striped dolphin has a similar size and shape to several other dolphins that inhabit the same waters (see pantropical spotted dolphin, Atlantic spotted dolphin, Clymene dolphin). However, its colouring is very different and makes it relatively easy to notice at sea. The underside is blue, white, or pink. One or two black bands circle the eyes, and then run across the back, to the...

Possible
About 20% of wildlife watchers report a Striped Dolphin sighting in Pico Island Natural Park (Azores) on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 13 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Striped Dolphin in Pico Island Natural Park (Azores) on a given day, against under 5% in April, June and September–October, the lowest months. January has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Striped Dolphin sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Pico Island Natural Park (Azores), in our data
Pico Island Natural Park (Azores) is the only park on Wallace's Line with enough records to rate Striped Dolphin sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Striped Dolphin is recorded against all the mammals logged in Pico Island Natural Park (Azores) (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
