Sunbathing sunfish mellows in Courtmacsherry

It is thought that these weird fish (so many fish are “weird” that I use the word advisedly) do actually lie flat on the surface to bask.
Normally, these fore-shortened, tail-less fish swim laterally, the dorsal fin of the rounded body pointing skyward, the other toward the depths. But when the sun shines, they often lie on the surface like a very unusual flatfish, presenting themselves to the warming light or to gulls that might do them the favour of picking parasites off their grey and shimmering skin.
