The island water rail is a small dark bird with a sturdy body. It lives on cold islands near Antarctica and often runs along the ocean shore in search of food.
The island water strider differs from other striders by its very dark color and close connection to the seashore. It is important for the islands' nature because it eats insects and helps maintain balance in the coastal ecosystem.
Immature form that undergoes metamorphosis before adulthood.
