Scientists studying reef fish communities have found that the depth of the reef system at Cabo Pulmo has significant positive effect on the number of species present and their populations. [16] Researchers explain that big predators such as whales, dolphins, or sea lions enjoy taking dives to the deeper coral at around 40 to 50 feet. [9]
Consequently, the predators and prey will be locked in an evolutionary arms race, each looking to gain the upper hand on the other. The presence of fish predators play a large role in the size, shape and swimming performance of the Lithobates clamitans tadpoles. The presence of these predators in their habitat causes the tadpoles to develop ...

[1] Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
