Diodon hystrix is a species of porcupine fish. These fishes are short and broad-bodied, with large eyes and spines covering their skin. Like puffer fishes, they inflate their bodies when threatened.
Flounders travel over the seafloor by undulating their entire body. As bottom-dwelling fish, they typically remain motionless on the substrate, often partially covered by sand or mud, until they need to move or pursue prey.12
