Answer:

Fish and other aquatic organisms use gills to take up oxygen dissolved in the water and diffuse carbon dioxide out of the bloodstream. Some insects utilize a tracheal system that transports oxygen from the external environment through openings called spiracles.

The word caterpillar refers to the larval stage of the butterflies and moths, so all caterpillars become either a butterfly or a moth. There are, however, some larval insects that look very similar to caterpillars.
