Swim outdoors and you’ll encounter wildlife. Creatures and plants inhabiting the water are one of the most distinctive differences between swimming outdoors and swimming indoors. They can be a source of delight and sometimes a worry. I’ve started writing a column for Outdoor Swimmer on wildlife for swimmers, exploring what to look out for, where to look for it and how to enjoy it.
