In recent years there have been some marked changes in distribution of plant and animal species, terrestrial and marine, in the UK and a trend of movement northwards by 'warmth adapted' biota is now a recognised feature. Fair Isle is geographically ideally situated to monitor any changes in climate and species distribution.
New invertebrates for the Fair Isle list are an annual occurrence. This does not mean that they are all new arrivals, however, some recent additions are species which had probably been overlooked in the past.
The following is a selection of marine fauna which have been found by island residents whilst rock-pooling along accessible coast and shore areas of Fair Isle.
