[Small-spotted] catshark is a species of shark that can be seen in the sea and ocean that surrounds Ireland and the Northeast Atlantic Ocean and the Mediterranean Sea. The catshark is a predatory shark and it likes to hunt and eat a variety of aquatic creatures. This catshark found its way out off the Irish Sea and into Howth Harbour in Dublin, Ireland. It found a great place to hunt and catch fish when it gets hungry, a predatory shark like this will have no problem catching fish in Howth Harbour.
