Located just outside the village of Brynsiencyn, Anglesey Sea Zoo claims to be the largest aquarium in Wales and displays over 150 native species.

The zoo hosts a conger eel, a shark pool, a kelp forest,[2] and runs the Lobster Hatchery of Wales.

The zoo is one of the few places in the world that has been able to successfully breed and sustain native short-snouted seahorse.

For the 2015–16 association football season the zoo were the away shirt sponsors for Welsh Premier League side Bangor City F.C.
