eväkalat

Eväkalat is a Finnish term referring to fish that possess fins. This broad category encompasses a vast diversity of aquatic vertebrates belonging to the superclass Pisces. Finnish classification of fish commonly uses this term to distinguish them from other aquatic animals. The defining characteristic of eväkalat is the presence of fins, which are used for locomotion, balance, and steering in water. These fins can vary greatly in size, shape, and number depending on the species.

Common examples of eväkalat found in Finnish waters include various species of perch, pike, salmon, herring, and cod. These fish inhabit a range of aquatic environments, from freshwater lakes and rivers to the brackish waters of the Baltic Sea and the open ocean. Their diets, reproductive strategies, and physical adaptations are as diverse as their habitats. Many species of eväkalat are of significant ecological importance, forming crucial links in aquatic food webs, and several are commercially or recreationally fished. The study and classification of these finned aquatic animals are central to the field of ichthyology, the scientific study of fish.
