Pygmy Sperm Whale

• Irish name: An Chaisealóid beag
• Latin name: Kogia breviceps
• Size: 3 – 4.3 m
• Diet: Squid

DESCRIPTION:

The body’s overall appearance is stocky with a square head and triangular dorsal fin ¾ way along the back. Narrow, pointed teeth are only present in the lower jaw. The body’s colouration is light grey along its upper surface and light white underneath. A diagnostic “false gill” is present on the side of the head which gives an overall shark-like appearance.

BEHAVIOUR:

Very little is known about this species globally. They are inconspicuous at the surface due to their small size, do not appear to approach boats but occasionally breach.

IN IRELAND:

Including historical records dating back to 1966, 11 pygmy sperm whales were found stranded in Ireland. Most were found on the south, southwest coast with additional sightings in Dublin and Wexford. One whale was salvaged by the IWDG and its skeleton is on display in the Shannon Dolphin Centre. This species has never been observed alive in Irish waters.
