What is a mammal that spends much of its time in water and lays eggs?

Answer 1

No mammal lays eggs in the water.

The platypus and echidna are both egg-laying mammals, and the platypus digs a burrow with a chamber in a riverbank or beside a pond or creek. However, the eggs are meticulously kept dry at all times.

Answer 2

No mammal lays eggs underwater.

There are only two egg-laying mammals. The platypus digs a burrow in the riverbank above the waterline, while the echidna actually deposits its egg directly into a rudimentary pouch it develops during the breeding season.

Answer 3

The platypus is an egg-laying mammal which spends most of its waking time in water. It does not live in water, but it does hunt in the water, making hundreds of dives daily to find its food.

The only other egg-laying mammal is the echidna. It does not spend time in the water (although it can swim).
