What are the characteristics of Osteichthyes?
Like all fishes, Osteichthyes are cold-blooded vertebrates that breathe through gills and use fins for swimming. Bony fishes share several distinguishing features: a skeleton of bone, scales, paired fins, one pair of gill openings, jaws, and paired nostrils.
Do sunfish live in cold water?
These creatures are restricted to oceans with temperatures higher than 54º F. In areas with lower temperatures, these fish will become disoriented and eventually die, unless they move to warmer water. This is likely because they require surface basking to thermoregulate, and cannot thermoregulate in colder waters.
Do sunfish live in saltwater or freshwater?
Centrarchid fish in North America number some thirty strictly freshwater species and include three generalized subdivisions: black bass, crappie, and the true sunfish. All of these are warm water species with similar or overlapping habitat.

Why do fishes need habitats?
Most marine fishes start their lives offshore as eggs the size of a pinhead. Then they change into larvae and ride the tides and other currents toward the coasts, where they must find safe places to feed and grow without getting eaten by one of the many predators in the sea. In other words, they need habitats.

Where do sunfish live in the winter?
Bluegill and sunfish start their winters in shallow water, typically in shallow bays and coves, and near the mouths of creeks and other inflows. Look for plenty of live vegetation in these spots before the ice starts to form, and mark the location of the weed beds.
Do sunfish live in deep water?
Scientifically known as Mola mola (which is where its common name “mola” comes from), the ocean sunfish tends to make its home in the deep waters of temperate and tropical oceans. Their large, silvery bodies can occasionally be seen near the surface, where they go to soak up the Sun’s rays.
Can sunfish live in brackish water?
Life History They can survive in salinities up to 20 ppt but in California they tend to avoid brackish water. Hard shelled invertebrates make up the majority of the redear sunfish diet, with bottom dwelling snails and clams and aquatic plants being the most common targets.
