What are the Cold blooded animals that hatch from eggs?

You're looking for oviparous ectotherms, which are animals that lay eggs and rely on external sources of heat to regulate their body temperature. Here are some examples:

Reptiles:

* Lizards: Iguanas, geckos, chameleons, monitor lizards, etc.

* Snakes: Pythons, boas, vipers, cobras, etc.

* Turtles: Sea turtles, freshwater turtles, tortoises

* Crocodilians: Crocodiles, alligators, caimans, gharials

Amphibians:

* Frogs: Bullfrogs, tree frogs, poison dart frogs

* Toads: American toads, European toads

* Salamanders: Newts, mudpuppies, axolotls

Fish:

* Sharks: Hammerhead sharks, great white sharks, tiger sharks

* Rays: Stingrays, manta rays, eagle rays

* Other bony fish: Many species lay eggs, including trout, salmon, and catfish

Birds: While birds are warm-blooded, they are also oviparous, meaning they lay eggs.

Important Note: Some animals, like certain species of snakes, are capable of giving birth to live young (viviparous). However, most reptiles and amphibians are oviparous.
