Marine scientists have discovered a “very rare” shark nursery in deep waters some 200 miles off the west coast.
The nursery was discovered during an investigation of Ireland’s deep ocean territory, and shows the seabed littered with eggs, or so-called “mermaids' purses”.
Images show very large numbers of egg cases filmed on the seafloor at depths of up to 750 metres.
It's understood they could belong to the Blackmouth catshark and the Sailfin roughshark.
The nursery was discovered during the SeaRover survey undertaken last July, which was exploring Ireland’s deep-water coral reef systems.
The footage was captured by the Marine Institute’s remotely operated vehicle deployed onboard the Irish Lights Vessel the Granuaile.
