Fish that live in murky water most likely have larger, more developed ___. dorsal fins. olfactory lobes. rosettes. pharyngeal teeth.

olfactory lobes

Explanation:

The correct answer would be olfactory lobes.

Murky waters are generally dark, and contains very little (low) light. Fishes that live in murky water need to be specially adapted in order to be able to live in such environment. These adaptations could be in terms of:

A well developed lucidum tapetum, a layer of protein crystals known as guanine which enables them to see through low light and act as a kind of 'night vision'.A well developed olfactory lobe which receives and process information from the olfactory nerve with high efficiency and generally serves to improve the sense of smell.
