Answer:

c) They develop one large claw and one small claw

As fiddler crabs grow from juveniles to adults, they undergo a fascinating transformation in their claw size. In their juvenile stage, fiddler crabs have two claws that are approximately equal in size. However, as they mature into adults, most individuals develop one large claw and one small claw.

This unique characteristic of fiddler crabs showcases an interesting aspect of their growth and development. The change in claw size serves a specific purpose in their behavior and reproductive strategies.

The transformation in claw size from juvenile to adult fiddler crabs is an example of sexual dimorphism, which refers to the physical differences between males and females of the same species. Males typically have one significantly larger claw than the other, which they use for communication and courtship rituals.
