McDonald's Happy Meal web site confirms that the October 2015 kids' meal theme will be based on the current film Hotel Transylvania 2 (not The Nightmare Before Christmas, which was released back in in 1993).
There are differences in the shell textures of oysters and clams. The shell of a clam is smooth and shiny while an oyster has a rough outer shell. Both the organisms take in water through the shells but the filtering procedure is different. Oysters produce pearls which are in much demand but clams do not.
Snails. The main difference between slugs and snails is the equipment the snail comes with; his shell, which grows along with his body. Most snails are gray, but the shells can range from white to brown or almost black, and be mottled or striped.lugs and snails are mollusks, the same family of creatures claiming oysters, octopus, squid and clams. There are more than 60,000 species of snails and slugs. The varieties living in the sea begin life as larvae floating about in plankton. Land and freshwater slugs and snails typically hatch from eggs.
