What is horsehair crabs?

Horsehair crabs, also known as the Japanese mitten crab, are a species of freshwater crab native to East Asia. They are named for their long, hairy legs and body which resembles a horse’s tail. These crabs can grow up to 10 cm in length and can weigh up to 200 grams.

Horsehair crabs are omnivores and feed on a variety of animal and plant matter. They are typically found in rivers, lakes, and estuaries and can tolerate a wide range of water temperatures and salinity levels.

These crabs are highly valued in Japanese and Chinese cuisine, and are considered a delicacy. They are often boiled and served with a dipping sauce, or used in various traditional dishes such as sushi, soup, and dumplings.

However, horsehair crabs are considered an invasive species in many parts of the world, including Europe and North America. They can disrupt local ecosystems and outcompete native species, and their burrowing habits can cause damage to infrastructure such as riverbanks and bridges. As a result, many countries have implemented measures to control their populations.
