Land dwelling animal's eggs have shells (hard or soft) to keep them from drying out. Fish eggs don't need shells because being in water they won't dry out.
Because they have to be soft to live in water.
Reptile eggs are soft-shelled so that the babies can break out of the shells. Bird eggs are hard-shelled, because baby birds use their beaks to crack the shells of their eggs, but since reptiles don't have beaks to use to break their shells, their eggs have to be soft-shelled.
The eggs have hard outer shells. After they are laid, most birds incubate them until they are hatched.
Hens are birds.Most (but not all) reptiles, amphibians and fish lay eggs.In addition, there are two types of egg-laying mammals, known as monotremes. The platypus and the echidna are monotremes.
no,some either lay eggs or give birth to live young

Yes. Penguins are birds, and birds reproduce by laying eggs with hard shells. This is different from the eggs of reptiles and monotremes, which have leathery shells.

I've never heard of a spider with hard eggs. I always heard they were soft.
Turtle eggs (and tortoise eggs) can be either hard or soft-shelled, depending on the species.
Yes, it does DEFIANTLY! cockroaches lay there eggs with hard shells, as it easier for cockroaches to reproduce.. .. HOPE IT HELPS! :) :) :) :)
Because they only can produce little offspring, unlike fish who produce millions of eggs and fertilize them afterward. Also, reptile and bird egg shells are tough making it hard to fertilize when fish eggs are more like jelly.

producing fishFirst of all you need a female and a male fish but its hard to tell what gender a fish is .In the rite surcomstances the female fish will lay her many eggs and afterwoods the male fish will insert his sperm into the eggs. They dont have sex.But its hard for fish to lay eggs in captivity
Yes, but they still have shells. Their shells are just a moist material instead of a hard one.
Shelled or not, eggs should be stored under refrigeration.
