birds evolved from reptiles.
No, only reptiles, mammals, and birds have amniotic eggs.
Mammals, birds, and reptiles lay amniotic eggs, and frogs and toads are none of these, so, no, frogs and toads do not have amniotic eggs. Amniotic eggs contain a yolk and aid in gas and energy exchange.
No, reptiles, mammals and birds have amniotic eggs because they lay their eggs on land.
Yes, a chicken egg is considered amniotic because it contains an amniotic membrane that surrounds and protects the developing embryo inside the egg. This membrane helps provide a suitable environment for the embryo to grow and develop.
Eggs laid by mammals, birds and reptiles. They have a membrane that contains fluid. There is amniotic fluid around the embryo. It also has a protective shell that provides air to pass through.
Reptiles
No, only reptiles, mammals, and birds have amniotic eggs.
Mammals, birds, and reptiles lay amniotic eggs, so, yes, owls have amniotic eggs. Amniotic eggs contain a yolk and aid in gas and energy exchange.
Mammals, birds, and reptiles lay amniotic eggs, and frogs and toads are none of these, so, no, frogs and toads do not have amniotic eggs. Amniotic eggs contain a yolk and aid in gas and energy exchange.
They are called amniotic eggs.
No, reptiles, mammals and birds have amniotic eggs because they lay their eggs on land.
Reptiles and birds have amniotic eggs, as well as the occasional mammal like the platypus and echidna.
Yes
Yes, owls do have amniotic eggs. Like all birds, they lay eggs that are encased in a hard shell, which provides protection and prevents desiccation. Amniotic eggs are a characteristic of reptiles and birds, allowing them to reproduce in a terrestrial environment. The eggs contain membranes, including the amnion, that help support the developing embryo.
No, squids do not have an amniotic egg. Amniotic eggs are characteristic of reptiles, birds, and some mammals, featuring a protective amniotic membrane. Squids belong to the class Cephalopoda and reproduce by laying eggs that are not amniotic; their eggs are typically encapsulated in a gelatinous mass and develop outside the mother's body.
It is not so simple. Most reptiles do have amniotic eggs, but a few species give live birth. Conversely, birds and monotreme mammals also lay amniotic eggs.
Mammals (monotremes only), birds, and reptiles give birth to amniotic eggs, which contain a yolk to nourish the developing organism. Amniotic eggs protect the developing organism, as well as aid in gas and energy exchange. chorion
