Which one of the following makes a tool with a stick to scrape insects from a hole in a tree or a log of wood?
Show answer
Answer: B. Orangutans are known to strip a stick and use it to pull insects and honey out of holes in trees. Tool making like this is mostly seen in great apes.
Watch for: Sloth bears eat insects from logs, but they use claws and suction, not sticks.
Why the other options are wrong
- A. Wrong because fishing cats catch fish with their paws and do not make tools.
- C. Wrong because otters (sea otters) use stones to crack shells but do not make stick tools for insects.
- D. Wrong because sloth bears suck termites out with their lips and long claws, not with tools.
