The great ramshorn snail (Planorbarius corneus) is a relatively large species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae. The shell of this species appears to be dextral in coiling, even though it is in fact sinistral or left-handed.
Mexican dwarf crayfish (Cambarellus patzcuarensis) is a crayfish in the family Cambaridae. Most specimens found in the wild are brown, sometimes with a gray or blue tint. Cambarellus patzcuarensis var. "Orange" (Mexican dwarf crayfish, sometimes Mexican dwarf orange crayfish) is an orange-coloured mutation often held in aquariums, but this form is rarely found in the wild. The species is named after Lake Pátzcuaro in Michoacán, Mexico.
