The Amazon is home to many unique species, including Inia geoffrensis, the pink river dolphin. It is one of a handful of species of freshwater dolphins found in the world. Unlike its saltwater relative, which may pass through freshwater waterways from time to time, the Amazon River dolphin can only survive in fresh water. This species is found in the Amazon and Orinoco Rivers, mostly in Brazil, Bolivia, Ecuador, Venezuela, Colombia, Guyana, and Peru. During the rainy season, the dolphins swim through the flooded forests of the Amazon and return to the main river once flooding has stopped. They have adapted well to their habitat.


Similar to saltwater dolphins, the Amazon River dolphin feeds on the various fish species that share its habitat. Its strong, toothy jaw allows it to eat turtles and crabs, too. The males can grow up to eight feet long, but the females are smaller at seven feet. These dolphins are usually gray in color as young dolphins, but their skin turns pink over the years, although scientists can't agree on why this happens. Some think it is for camouflage in the murky water, while others believe it is because they get many scratches from fighting. Another interesting fact about these dolphins that makes them unique is their ability to turn their heads 90 degrees. Other dolphins cannot do this. They can also move their fins in different directions at the same time, which helps them swim through the cramped, flooded forests. This ability helps them get around their watery world.


Although they have adapted well to their freshwater habitat, they are also limited by where they live. As populations grow and humans move further into the Amazon in search of fish and other resources, these dolphins suffer. Many become entangled in fishermen's nets and die, while others have difficulty finding food because the flow of the river is interrupted by hydroelectric dams. While the Amazon River dolphin has not been listed as an endangered species yet, these threats to their habitat could mean that we find them on the endangered species list sooner rather than later.


How can you recognize that this article is a scientific text? (2 points)

Answer 1

Step-by-step explanation:

Answer 2

There are several ways to recognize that this article is a scientific text:

1. It presents factual information about a specific species of animal, including its habitat, feeding habits, physical characteristics, and adaptations. The article uses scientific names for the species (Inia geoffrensis) and provides specific details about its behavior and physiology.

2. The language used in the article is precise and technical, using scientific terms and concepts such as "freshwater dolphins," "toothy jaw," "hydroelectric dams," and "endangered species list." The article also includes information about the debate among scientists regarding the reason for the pink skin color of the dolphins, which shows the scientific process of asking questions and forming hypotheses.

3. The article presents a balanced view of the topic, including both the positive adaptations of the Amazon River dolphin and the threats to its habitat and survival. This approach is typical of scientific writing, which seeks to present a comprehensive and evidence-based view of a topic.

Overall, the use of precise language, factual information, and a balanced view of the topic are all characteristics of scientific writing, and therefore indicate that this article is a scientific text.
