There are 84 mammal species (with two uncertain) recorded in Sweden according to the IUCN Red List.
They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater.
The most distinguishing feature of bats is that their forelimbs are developed as wings, making them the only mammals capable of flight.
The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas).
Shrews and solenodons resemble mice, hedgehogs carry spines, gymnures look more like large rats, while moles are stout-bodied burrowers.
