The long-spine porcupine fish is an omnivore that feeds on mollusks, sea urchins, hermit crabs, snails, and crabs during its active phase at night. [5] They use their beak combined with plates on the roof of their mouths to crush their prey such as mollusks and sea urchins that would otherwise be indigestible. [6][7]
The spot-fin porcupinefish is a medium-sized fish which grows up to 91 cm, but the average size mostly observed is 40 cm. [2] Its body is elongated with a spherical head with big round protruding eyes, and a large mouth which is rarely closed. The pectoral fins are large, the pelvic fins are absent, and the anal and dorsal fins are close to the ...
Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.

Fish anatomy. Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. [1] In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or ...
