Eftlings are about three inches long and found in freshwater streams and pools. They can survive in saltwater, but the salt crystallises around their gills and it's very painful to get out, so they tend to avoid saltwater. They eat algae and weeds, and are very fast little things. They use their tails as rudders, and their hands and feet are webbed. In mating season they race each other, pairing up according to speed. They lay eggs (one at a time) and the young are able to swim as soon as they hatch. They stay with their parents for about a year and then leave to join groups of other youngsters to grow up in nursery pools until they mature sexually. Eftlings communicate with whistles and clicks.
