Lesson Express
Q: Describe an otter when it is fishing.
A: It is very quick and agile; it stays underwater for a long time; it paddles with its paws and wiggles its tail; it misses a lot.
Q: In what ways do family groups make otters stronger?
A: Cubs can’t catch fish themselves, but adults share their catch; in a group, otters can fend off a crocodile.
Q: Why do you think the crocodile doesn’t attack one of the otters?
A: Student responses will vary. Students may suggest that it is distracted by the others or afraid the others will attack it if it does.
