Orca Orcinus orca 

The Orca (Orcinus orca) is the largest member of the dolphin family and one of the ocean's most formidable predators, recognised worldwide by its striking black-and-white patterning. In British waters it is most regularly encountered off northern Scotland, where small resident and transient groups hunt marine mammals. Sightings in the southern North Sea and off Suffolk are rare, typically involving solitary individuals or small groups moving through the area. Any confirmed record off the Suffolk coast is of considerable interest and should be submitted to national cetacean recording schemes. Strandings, whilst very rare, have occasionally been reported from the East Anglian coast. Image: © James Maughn, iNaturalist.
