Guppies with low or no predation, tend to not blend in and are brighter with more and larger spots (Endler, 1978).

Although brighter males are often preferred by the females, they are also more likely to…

After a few minutes my friend Gage shouted, “Let’s Go!” and the four of us swam onwards toward the raft.…
