Rákfajta

Rákfajta is a Hungarian term that translates to "type of crab" or "crab species." It is a general classification used to describe various kinds of decapod crustaceans belonging to the infraorder Brachyura, commonly known as true crabs. These marine and freshwater animals are characterized by their thick exoskeleton, a single pair of claws (chelae), and four pairs of walking legs.

The term rákfajta encompasses a wide array of species, each with distinct physical characteristics, habitats, and ecological roles. Some well-known examples include the edible crab (Cancer pagurus), the blue crab (Callinectes sapidus), and the king crab (Paralithodes camtschaticus), although the latter is technically a lithodid crab and not a true crab. The diversity among rákfajta is vast, ranging from small pea crabs that live commensally with bivalves to large spider crabs that can have impressive leg spans.

Crabs are found in almost every marine environment, from shallow coastal waters and coral reefs to the deep sea. Some species are also adapted to freshwater and even terrestrial environments. Their diet varies significantly, with some being scavengers, others predators, and some filter feeders. The term rákfajta serves as a broad category for discussing these diverse arthropods in a general context within the Hungarian language.
