Meet the Daring Matador Guppies of Trinidad

Guppies have developed a unique defense mechanism against predators like cichlids. By changing their eye color to black, they attract attacks to their heads, allowing them to dodge and escape. This tactic is facilitated by melanophores, which rearrange melanin to alter eye color. Larger guppies are more adept at this, suggesting an evolutionary advantage. This strategy is akin to a matador's cape, misleading predators and enhancing survival.

Describe the role of melanophores in the guppies' ability to change eye color. How does this process work?

What adaptations have larger guppies developed in relation to their defense mechanism against predators?
