From its impact on society to its implications on everyday life, Uropod has generated intense debate and aroused great interest in various communities. Throughout these pages, we will delve into different aspects of Uropod, from its origin to its evolution over time, providing an exhaustive and updated analysis of this very relevant topic. By combining data, expert opinions, and testimonials from people who have been impacted by Uropod, we aim to offer a broad and balanced view that enriches our readers' understanding of this fascinating topic.

The tail of Nephrops norvegicus – the uropods flank the telson; a diaeresis is visible on the exopod (outer part) of each uropod.

Uropods are posterior appendages found on a wide variety of crustaceans. They typically have functions in locomotion.

Definition

Uropods are often defined as the appendages of the last body segment of a crustacean.[1] An alternative definition suggested by Frederick R. Schram restricts the term to those structures arising from the segment before the anal segment (the segment which carries the anus).[1] Under this latter definition, the appendages of the anal segment are caudal rami, which are analogous to uropods.[1]

Form

Uropods are typically biramous – comprising an endopod and an exopod. The exopod is typically the larger, and may be divided in two by a transverse suture known as the diaeresis.[2][3] The uropods may work in concert with the telson to form a "tail fan".[4]
