The Playful World of Otters: IELTS Reading Passage with Questions & Answers

The Playful World of Otters Reading Passage:

Otters, with their charismatic appeal and frolicsome behaviors, have fascinated observers and researchers alike. These semi-aquatic mammals, belonging to the family Mustelidae, are not only skilled hunters but also play a crucial role in their ecosystems. Found in a variety of aquatic habitats, they are known for their impressive ability to use tools, something once thought unique to primates and humans.

The most commonly recognized species, the North American river otter, is a symbol of aquatic health, indicating clean, unpolluted water bodies. Otters have dense fur – about 250,000 to one million hair follicles per square inch, which insulates them against cold waters. This fur requires constant maintenance, and as such, otters are often observed grooming themselves to maintain the insulating quality of their fur.

Otters' diets primarily consist of fish, but many will also eat amphibians, crustaceans, and occasionally small mammals and birds. What is truly remarkable is their use of rocks to crack open shellfish, a skill that exemplifies their problem-solving abilities.

Social structures among otters vary significantly between species. For example, sea otters may float in groups called rafts, sometimes holding paws to stay together, while giant otters in the Amazon basin are more territorial and live in family groups that vigorously defend their territories.

Conservation efforts for otters have seen varying degrees of success. Pollution, habitat destruction, and hunting for their fur have led to the decline of otter populations worldwide. However, through concerted conservation efforts, such as the banning of harmful pesticides and protection of their habitats, some species of otters have begun to make a comeback, serving as a beacon of hope for environmentalists.
