4. Differences in behavior between male and female crabs
In addition to physical characteristics, male and female crabs also differ in behavior. Male crabs are usually more active and aggressive, especially when fighting for territory or mates. Female crabs are relatively gentle, especially during the breeding season, and will show more protective behaviors.
