The minimum age to obtain one's driverâs license should not be raised to 18 because 16-year-olds have a much more focused mind. If you change the minimum driving age to 18, it will be very little different from 16-year-olds because either way they wouldn't have very much driving experience.

Physical Characteristics. All cone snails are wide at one end and narrow at the base (the typical âconeâ shape). All have spires, (whorls above the body whorl) of varying heights at the wide end. A whorl is a full turn of the shell.Shell bodies (whorls) can be dull to very shiny, smooth to lined and bumpy.one snail venom is very complicated chemically, varying widely in its makeup from species to species, whether a piscovore, the most toxic, or a vermivore, the least toxic; and with each individual sting or attack. Cone snails are among the most toxic creatures on earth.
