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.
Both slugs and snails are gastropods and belong to phylum Mollusca. Both have soft bodies with a muscular foot. Both slugs and snails are similar in many respects but with only a few differences. One of the noticeable differences is that snails have a shell on their backs whereas slugs do not have shells. The shell is coiled and about one to one and one-half inches long. Both slugs and snails have either a dark green, tan, light gray, or black body. Some of the varieties have patterns or spots on their bodies.
