Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
Terns range in size from the least tern, at 23 cm (9.1 in) in length and weighing 30–45 g (1.1–1.6 oz), [1] [2] to the Caspian tern at 48–56 cm (19–22 in), 500–700 g (18–25 oz).

Some European herring gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, such as in Ireland, Britain, Iceland, or on the North Sea shores.
