Pistol shrimps amd gobies depend on each other for their shelter and protection and they have a beneficial relationship with each other. whats this symbiotic relation called

The symbiosis between a Pistol shrimps and gobies is called Mutual symbiosis. In this process both animals benefit. The shrimp creates and maintains a burrow for both the animals to live in, where as the fish offers protection from predators. When outside of their burrow the fish keeps a keen eye to spot any predator around and sends a warning to the goby through flicking of its tail in cases of a predator approaching.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
