Malacologist → It is formed from "malaco-" (from Greek "malakos", meaning soft) and "-logist" (from Greek "logia", meaning study or science). A malacologist is someone who studies soft-bodied animals, particularly mollusks.
Think of 'soft' ('malaco-') and 'study' ('-logist') to remember that a malacologist studies soft-bodied creatures like snails and clams.
