for an example... ducks & chickens lay eggs and yes, they do take care of their young for a little while. so.. yeah, they do
Marsuipials are warmblooded animals who do not lay eggs.
reptile are warmblooded animals. for example a lizard is reptile. it lat eggs.
Because ,just because
Many animals lay their eggs and leave them - eg the salmon, sea turtles, butterflies. Other animals eg the cuckoos lay their eggs and leave them to other animals to rear.
Probably yes, when a cold blooded animal such as a reptile (snake) lay their eggs they stay with them until the eggs have hatched and then off they go. While a warm blooded animals generally give live births (other than birds) they tend to stay with their young and care for them until they are old enough to take care of themselves.
Squids happen to not care for their young
Animals that take care of their young produce fewer eggs. e.g. crocodiles. Animals that leave their young to fend for themselves produce numerous eggs. e.g. fish. This is an energy balance. You spend little energy to produce eggs, but spend more energy taking care of your offspring. Conversely, you can spend lots of energy producing many eggs and spend little energy thereafter. It's a numbers game.
No. Arthropods are not warmblooded but they do lay eggs.
Frogs do not raise their young. Young frogs are strictly on their own.
Animals that produce many eggs in the hopes of increasing the likely hood of their offspring surviving, so when the parents don't take care of them this saves the adults time and energy.
Most frogs extensively care for their eggs and young.
No, rattlesnakes only eat small warmblooded animals (e.g. mammals, birds) and sometimes eggs. Rattlesnakes don't eat mushrooms.
