Still, a child with an egg allergy should get the flu shot in a doctor's office, not at a supermarket, drugstore, or other venue. And if the allergy is severe, it might need to be given in an allergist's office. If your child is sick and has a fever, talk to your doctor about rescheduling the flu shot.
There are about about 13,000 named genera for both Recent and fossil gastropods. They have a long and rich fossil record from the Early Cambrian that shows periodic extinctions of subclades, followed by diversification of new groups.he shell is partly or entirely lost in the juveniles or adults of some groups, with total loss occurring in several groups of land slugs and sea slugs (nudibranchs). Externally, gastropods appear to be bilaterally symmetrical. However, they are one of the most successful clades of asymmetric organisms known.
Snails are born with a small, soft, colorless shell called a protoconch, which then grows as the snail grows. Since snail shells are made up mostly of calcium carbonate, snails tend to have a very calcium-rich diet.Of interest, Stomatella snails are often mistaken for snails that are out of their shells, since Stomatella snails have transparent shells.owever, it can happen by accident, which usually leads to the snail dying. It's thought to be possible that some snails could live without their shells, until they form a new one, but this is considered unlikely.
