Characteristics
Paractaea crabs are characterized by their relatively small size, typically less than 5 centimeters in carapace width. They have a broad, flattened carapace with a distinct heart-shaped outline. Their bodies are covered in short, dense hairs, which give them a velvety appearance.

They have prominent, pointed eyes and small, short chelipeds (claws).
