Pulse. Pulse. William and I were drawn towards this tank in the Horniman Museum’s Aquarium.
Diaphanous sugar-pink wraiths trailing long floating tendrils pulsated gently round their royal blue tank: hypnotic: mesmerising. They neither paused nor hurried. They simply oscillated, surged, ebbed, flowed. These ethereal creatures didn’t merit their prosaic name of Black Star Northern Sea Nettle. Who dreamed that one up?
When we finally left them to it, we discovered we hadn’t finished with pulsing creatures. Here was a Blue Spotted Ribbon-Tail Ray. He gently wove round the tank, his flat body slowly rippling to the rhythm of his inner pulse.
Then there were the frogs. Look at these two Amazon Milk Frogs. They had nothing to do but regard us without interest, as their chests swelled and deflated – pulse, pulse.
