Animals Lays Egg Without ShellsAmphibians (frogs, toads, salamanders) lay eggs without hard shells; their eggs are soft and gelatinous.Monotremes (platypus, echidnas) lay eggs with soft, leathery shells, not hard shells.Some reptiles (certain turtles and lizards) lay eggs with soft, leathery shells instead of hard shells.The key difference: amphibian eggs lack a hard shell entirely, while monotreme and reptile eggs have leathery soft shells.Animals that lay eggs without shells include amphibians like frogs, toads, and salamanders. Their eggs are soft, gelatinous, and lack a hard shell; instead, they have a protective coating and are often laid in water or moist environments. Additionally, monotremes such as the platypus and echidnas (egg-laying mammals) lay eggs with soft, leathery shells rather than the hard shells typical of birds and reptiles. Some reptiles, like many turtles and lizards, also lay eggs with soft, leathery shells rather than hard shells.
