Now I’ve got eggs to care for, I need to keep intruders away. This edible crab is too close and I’m concerned he wants to use those big claws to pick and eat my youngsters developing in their eggs. As you can see, I’m biting and pushing his leg to scare him off. He’s slow on the uptake so it can take a while but eventually he will get the message and shuffle off. Meanwhile, he is protecting his antennae, eyes and mouth from my attacks.
The velvet swimming crabs can be more difficult to chase away, as they like a fight. I use a different tactic with them because they are fast and have sharp claws. I harass them by darting in quickly so they don’t have time to nip me. I’m clever as well as very bossy!
