It’s been a while since I last wrote about my British Animal Challenge, but I haven’t forgotten it. I managed to tick another species on my list this Easter: the bottlenose dolphin.
Easter day was glorious down in Cornwall. Beautiful weather, and ideal for a walk. So that’s what we did. We followed the coast path from Godrevy Beach, up round Dean Quarry (more on that later).
Of course, whenever I’m by the sea I keep my eyes peeled for exciting marine wildlife. A reasonably choppy day means I can spot vast numbers of imaginary basking sharks. But that day wasn’t so good for spotting imaginary wildlife; too flat. Which meant, when I did spot a fin breaking through the surface of the water, I knew it was something real.
The binoculars came out, and I was able to tell it was some kind of dolphin. Or rather, dolphins. There was a group of five. They travelled parallel to the cliffs, not far out, for quite a while, giving us an excellent, prolonged view.
I couldn’t identify which species of dolphin they were there and then. I could tell they weren’t common dolphins or porpoises, both of which I’ve seen quite a few times before. But I didn’t know what they were.
As soon as we got back to an internet connection, I looked up an ID guide, and concluded that they were bottlenose dolphins. This was confirmed a week later when we went out on a wildlife cruise, and, chatting to Captain Keith found that they’d seen the same group of dolphins in the same place on Easter Sunday afternoon, and they were, indeed, bottlenoses. I also learnt that one of the 5 was a youngster, which I hadn’t realised.
Bottlenose dolphins are between 2-4m long, and impressively intelligent. They use sound for communication as well as hunting, and some have been trained by the military to locate sea mines. They can live for more than 40 years, and jump 6m in the air. They’re pretty impressive animals.
The area we saw them in is the Manacles Marine Conservation Zone, off the east coast of the Lizard peninsula. This is a very special area for marine wildlife, but is under threat from plans to open a superquarry. Aside from the noise of the blasting and loading, pollution risk, increased traffic through the site of special scientific interest and area of outstanding natural beauty, and light pollution, plans involve building a new breakwater out into the Marine Conservation Zone. It was lovely seeing the dolphins there (we often spot cetaceans in that area), but there’s a real question over the future of wildlife in that area.
