The tendency for marine fish to refuge in natural and artificial structures underwater is well documented, but the incidence of this behaviour among predatory sharks is not widely known. A sub-adult male nursehound Scyliorhinus stellaris was tracked by intermittent acoustic telemetry over 168 days in a tidal sea lough. This individual, in-between undertaking nocturnal foraging excursions, refuged in at least five different narrow-entrance holes. Refuge location was validated by underwater and surface observations during which time other nursehounds (sub-adult male and female), were also seen refuging, sometimes together. This indicates nursehound display philopatric behaviour centred on aggregation in ‘home’ refuges that, in this case, were labyrinthine rock systems.
