UC San Diego has discovered that some female soupfin sharks return to a specific area of La Jolla Cove once every three years for reasons that are not entirely clear.
The finding is based on the movements of 34 pregnant soupfins that were tagged with acoustic transmitters so that they could be tracked as they migrated between La Jolla and points to north, mostly the Northern Channel Islands and San Francisco Bay.
The sharks that returned in three-year cycles spent part of the summer in the warm shallows just south of La Jolla’s Marine Room. Their arrival coincided with their three-year reproductive cycle.
