Scientists believe that amphibians evolved from bony fish. C.

Answer from: Zaviahector1124

The correct answer is -

C. bony fish.

The bony fish evolved into two distinct groups, which are Sarcopterygii that contains the lobe-finned fish and Actinopterygii that contains ray-finned fish

The lobe-finned fish further evolved and gave rise to the tetrapods (which are the vertebrates with four limbs), represented by amphibians, reptiles, birds, and mammals.

These lobe-finned fish evolved and developed multi-jointed leg, such as fins with digits, which helped them to crawl along the side of sea.

Thus, they resulted in the evolution of amphibians.

Therefore, option C) Bony fish is the right answer.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
