Q

Describe the sneaking behavior seen in fish

A

Type I males are larger, build nests, and produce vocalizations to attract females. Type II males are smaller, do not build nests, and instead use a “sneaker” strategy, sneaking into Type I males’ nests to fertilize eggs. This allows Type II males to reproduce without the need for the resources and energy required to build and defend a nest.
