Atlantic White
Sided Dolphin

  • Irish name: An deilf bhánchliathánach Atlantach
  • Latin name: Lagenorhynchus acutus
  • Size: 2.7 m
  • Diet: Whiting, blue whiting & squid
DESCRIPTION:

They are a very stocky dolphin with a small beak, streamlined head, tall falcate dorsal fin and robust tail stock. They are dark on top and light coloured underneath but predominantly light grey along their sides with a white patch below the dorsal fin and a characteristic orange flare on the tail stock.

BEHAVIOUR:

They tend to move fast at the surface revealing the orange flare when diving. Breaching regularly occurs but bow riding is rare.

IN IRELAND:

This species occurs in offshore waters along the continental shelf mainly to the west and northwest. Inshore sightings along the south and southwest dolphin hotspots are extremely rare. A mass stranding involving 19 dolphins at Killala Bay, Co. Mayo in September 1994 became the first time in Europe that post-mortems for all animals involved in a mass stranding were carried out.
