Sea Turtles, Reptilian Amphibians That Are Classified GMAT Reading Comprehension

Reading Passage Question

Sea turtles, reptilian amphibians that are classified into seven distinct sub-species, are quickly beginning to rank among some of the most endangered species on the planet. These ancient reptiles are vital to Earth’s ecosystem because they feed on botanical life that grows on sea beds and thereby help maintain the natural habitat of several other marine life forms. Further, unhatched sea turtle eggs provide nutrients for plants that grow beneath the surface of the sea, which in turn strengthen sand dunes through their root systems and help prevent beaches from eroding.

Ironically, human attempts to preserve the marine environment in which sea turtles live are causing the species’ numbers to dwindle even faster. In an effort to protect sea turtles that nest on the beaches, in some popular fishing areas local authorities have placed restrictions on the amount of fishing in order to protect the turtles from being caught in fishing nets and drowning. However, the reduction in the amount of fishing in these areas has led to an increase in the numbers of the giant cuttlefish, which feed on the same underwater plants as the sea turtles do. The subsequent decrease in the turtles’ food source, particularly the sea grass that is part of the turtles’ staple diet, has not only led to an alarming reduction in the number of sea turtles in these areas but also affected the balance of the marine ecosystem in these regions.
