The marine life that we have around Anglesey is incredibly abundant. There are so many varieties of fish and mammals that arrive at our shores, on their migratory cycles. The migratory cycles are so predictable you can set your watch by them. The watery world that surrounds our island is truly packed with life, whether its fish, seaweeds, crab, lobster, sea birds, jelly fish and shark, we have it all here on Anglesey.
Our shorelines are packed with wonderful sea birds (see our blog on sea birds of Anglesey) and our waters are packed full of the most amazing marine life you can find anywhere in the world. That is a statement we can boast, as a marine geologist and oceanographer of ten plus years I can attest to that. We see small examples of it in fleeting moments, when the dolphins or bigger mammals break surface, but mostly the magic is happening beneath the surface.
I have been blessed to have grown up on the shores of Anglesey on the beach every day exploring, crabbing and fishing as a little one. I was never far from the beach most days, mind you you are never far from a beach in general on Anglesey. Consequently you build up a sort of affinity ad knowledge base of the ocean thats very rich. Most was passed down to me by uncles and god fathers who honed my fishing skills and knowledge. We where lucky enough to have a lot of fishermen, boat builders, captains and light house keepers in my family which allows for a fairly strong nautical genealogy.
My love of the sea is something I can’t quite explain to most people, its a deep rooted knowing that the sea means home. I find that even more so when I’m living on a boat also. I don’t think I could ever imagine not living near a water body of some sort, I think it would feel far to strange.
We wanted to write you a little guide to the marine life on Anglesey and north Wales and if you are a beginner give you a a background on all things marine life to help you on your way. I will do more detailed blogs on each one of these in the future, but for now, I will give an over view of the most abundantly found species of each in Anglesey in the summer months, enjoy.
