krabben

Krabben are decapod crustaceans commonly referred to as crabs in Dutch, German, and several other European languages. The term covers many species across multiple families and is used for crabs living in marine and coastal environments around the world.

Most krabben have a broad, laterally compressed carapace and a short abdomen tucked under the thorax. They typically have five pairs of legs, with the first pair modified into large claws.

Diversity within krabben is high. Some are true crabs with a broad shield-like carapace, while others are swimming crabs with flattened legs adapted for swimming. Color and pattern vary by species and habitat.

Ecology: Krabben are typically omnivores or scavengers, feeding on mollusks, worms, algae, detritus, and small fish. Many species are important predators in coastal ecosystems. Reproduction involves females carrying eggs under the abdomen until hatching, after which zoea or nauplius larvae are released into the water.

Human use: Krabben are fished commercially and recreationally in many regions. Crab meat is sold cooked or live and appears in soups, salads, sushi, and crab cakes. Regulations on size, season, and quotas are common to manage stocks.

Conservation and invasive species: Some krabben populations are threatened by overfishing or habitat loss. The European green crab (Carcinus maenas) is an invasive species in many regions, displacing native crabs and altering communities. Management efforts include monitoring and controlling introductions.
