Äyriäisillä

Äyriäisillä is a term often used in Finnish culture to refer to small crustaceans. This broad category encompasses a wide variety of marine and freshwater arthropods, most famously the shrimp and crab species. In Finnish cuisine, various äyriäisillä are considered delicacies. Shrimp, known as katkaravut, are frequently featured in salads and as appetizers. Crabs, such as raput, are especially popular during dedicated crayfish parties, a traditional summer event in Finland.

Beyond their culinary significance, äyriäisillä play a vital role in aquatic ecosystems. They serve as a food source for many larger animals, including fish and birds, and contribute to the decomposition of organic matter. Their shells are composed of chitin, which provides them with a protective exoskeleton. The diversity within the äyriäisillä group is immense, ranging from microscopic copepods to the larger, more familiar species. Their presence indicates the health of an aquatic environment.
