There are a number of other unique behavioural traits associated with "C.lavauxi" including its aggressiveness when cornered which is rather unusual for a crab, with its pincers raised to accentuate their size along with showing the paleness of their pincers. Their major body postures include being flat with their pincers folded and laying on the ground with their walking legs close and side-by-side. When in a raised position they place their body at a 45 degree angle with their back part still laying on the ground with their pincers resting still either flat or poised at the midway mark. Their final position is the tiptoe position with their body angled and lifted off the ground and in the air, pincers still folded but held off the ground with their walking legs fully extended.
