Question

all of the following traits are common in deep - sea creatures except:

a. large eyes.
b. dorsal fins.
c. exceptional size.
d. exaggerated jaws.

Explanation:

Deep - sea creatures often have large eyes (to detect faint light), may have exaggerated jaws (for catching prey in low - food environments), and some can be of exceptional size (due to factors like low predation and unique ecological niches). Dorsal fins are a common trait in many fish (not just deep - sea ones) but are not a trait that is uniquely or predominantly associated with deep - sea creatures in the context of being a “common trait” compared to the more specialized traits like large eyes, exaggerated jaws, or exceptional size in some deep - sea forms.

Answer:

B. dorsal fins
