✔ Sample Comprehension Question & Answer

Question: Why do scientists believe goblin sharks are active mainly at night and during twilight?

Answer: Scientists believe goblin sharks are active at night and during twilight because they have poor eyesight, which would make it hard to see during the day. Their ability to detect prey using electroreceptors (like the ampullae of Lorenzini) helps them hunt effectively in low-light conditions.
