The information below describes a relationship between a type of fish known as a goby and a species of blind shrimp.
The shrimp digs a hole that provides shelter for itself and the goby fish. The goby fish lives at the opening to the hole and watches for predators. When a predator swims by, both organisms quickly move farther into the hole for safety. The relationship between these two organisms is best described as
(1) competitive
(2) harmful
(3) beneficial
(4) predatory
(3) beneficial
