North Carolina reports of pygmy sperm whales trace mainly to deep water off Cape Hatteras, where the continental shelf narrows and the Gulf Stream runs close to the barrier islands. Some also come from strandings on the beaches, since this elusive whale is documented more often after washing ashore than during encounters at sea.
That pattern fits its biology: a compact, deep-diving whale that spends most of its life far below the surface hunting squid, only becoming visible to people when it surfaces briefly, strands, or is found on a barrier-island beach after storms push it inshore.
Records turn up across the year, with the state’s data showing loose peaks in February, September, and November. Because so much of this whale’s life happens well below the surface, sightings depend heavily on when animals happen to strand or surface near a boat, not on a predictable seasonal pattern.
