AMPHIBIANS• They lay soft eggs in water. They are

oviparous.• They have moist skin.• At first they breathe with gills and later

they develop lungs.• They live in water and on land.

FISH• They have scales and fins.• They breathe with gills.• They lay soft eggs in water.• They eat plankton, insects, other fish and
