Rare Sightings and Strandings

Of the 83 species of whales, dolphins and porpoises (cetaceans) currently recognised in the world, 24 species have been recorded in the waters off the west coast of Scotland in recent years. These records can be divided into those species that have been seen fairly regularly as live animals and those that are seen quite rarely or as stranded animals.

Follow the links below to find out more about the whales and dolphins that are seen infrequently or as stranded animals. These include animals that are normally associated with deeper waters, such as the beaked whales, and those thought to be outside of their distribution limit, such as Fraser’s dolphins, beluga whales and narwhals. In this section you will also find information about regularly sighted cetaceans and some of the other marine animals seen in the Hebrides.
