Stenella coeruleoalba - Striped Dolphin

Range & Status

This species inhabits subtropical and warm temperate waters, occurring in the north

Atlantic in offshore areas to the west of the Iberian Peninsula and France. There is also a population in the Mediterranean. It is rare in UK waters and is recorded mainly from the south-west approaches to the English Channel and off Southern Ireland. Occasional sightings and strandings have occurred as far north as Shetland. There is no clear evidence of recent changes in population, however, an increase in records between the 1980s and 1990s in northern Britain suggests a possible recent northward extension of their range (UK Biodiversity Group, 1999).


Strandings were recorded in 1939 (1), 1975 (1), 1984 (2), 1986 (2), 1992 (1), 1994 (1), 1995 (1), 1996 (1) 1997 (1), 1998 (5), 1999 (1), 2000 (2), 2001 (2), 2002 (3), 2003 (5), 2004 (2), 2005 (3), 2006 (2), 2007 (1), 2008 (1) live stranded and was euthanased.


1998 (3), 1999 (1), 2000 (4), 2001 (1), 2003 (1), 2005 (1), 2007 (1).
