The sailfish is named for its sail-like dorsal fin and is widely considered the fastest fish in the ocean, clocking in at speeds of 70 mph. Sailfish also work together, using their dorsal fins to create a barrier around their prey, in order to feed on smaller schooling fish, such as sardines and anchovies.
What is the habitat of a sailfish?
Habitat of the Sailfish Both species utilize pelagic, or open ocean, habitats. They do not live in close association to the coasts or the sea floor. More specifically, they live within the epipelagic zone, or the area from the surface of the ocean to as deep as light penetrates.
Do mammals have backbones?
The 5 groups of vertebrates (animals that have a backbone) are fish, amphibians, reptiles, birds, and mammals. Invertebrates are animals that do not have a backbone. A spider is an invertebrate because it is an animal without a backbone. Spiders are classified as arachnids (not insects).

Is there a difference between sailfish and swordfish?
