On September 11, the scientists from Scripps Institution of Oceanography found out that a specific species of crabs growl at the predators. This sound is similar to aggressive interactions that both genders of crab make. This discovery made by Jennifer Taylor, a Scripp's scientist along with Maya deVries is the first instance where an animal uses stomach sounds to communicate, which further means that their claws are available to attack and fight with predators. When agitated, these crabs grind teeth present in their gastric mill. 

The unique nature of crabs

The rumbling sounds of the particularly grumpy crabs are made by grinding teeth of the foregut. The sound then generated is loud enough for the people to hear with naked ears. According to Jennifer Taylor the biologist from Scripps, California revealed that these abdominal vibrations are 'definitely' an advantage especially when the predators are up close to them. Reportedly, the crabs can pull out their claws and be entirely prepared to attack while producing these sounds. In case of a situation where their claws are busy, the crabs can choose to generate similar sounds from their internal system.
