- Compares an animal's size or ability to a familiar reference
- Shows enthusiasm for superlative animal facts
“If you ask your child which animal is the fastest or the biggest in the world, can they name some record-holders like the cheetah or blue whale and compare their size to something familiar, like 'a blue whale is as long as three buses'?”
