Fishes and their characteristics that distinguish them from other animals. Introduction: Around 550 million years ago (mya), that is in the early Paleozoic era, the fishes have appeared first. The fishes approximately comprise around half of 64,000 vertebrate species. Among the living groups of fishes, the five main groups include cartilaginous, lobe-finned, ray-finned fishes, lampreys, and hagfishes.

Expert Solution & Answer

Explanation of Solution

The fishes are defined as the aquatic vertebrates having gills as well as appendages in the form of fins. They mainly differ from other animals in their bodies, which is streamlined that allows the fishes to move through the water. They move at angles or forward using the fins. They are capable of maintaining the composition of body fluids in seawater as well as freshwater environments as they have excellent organs for the exchange of water and salt. They have excellent visual as well as olfactory senses. The gills of fishes are very effective in oxygen extraction; even a very low amount of oxygen is present. They also have a lateral-line system and this provides sensitivity to vibrations and water currents.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
