Atlantic White-sided Dolphin Lagenorhynchus acutus

The Atlantic White-sided Dolphin (Lagenorhynchus acutus) is a robust, fast-swimming dolphin of the open North Atlantic, most commonly associated with deeper offshore waters. In Britain, it occurs primarily off northern and western coasts, and records from the southern North Sea – including Suffolk waters – are relatively uncommon, typically involving stranded individuals or occasional offshore sightings. Suffolk strandings, though rare, are recorded, and any occurrence is of note given the species’ general preference for deeper Atlantic waters. All strandings should be reported promptly to the British Divers Marine Life Rescue or the Cetacean Strandings Investigation Programme. Image: © Laurie Sheppard iNaturalist.
