The guppy (Poecilia reticulata) is a small colourful species of freshwater tropical fish which makes it popular as an aquarium fish. Guppies often display elaborated patterns on their tail fin, with the male being generally more brightly coloured; female guppies however are larger in size and have a shorter tail as compared to the males. The guppy is an omnivorous animal and eats a wide range of organic matter that is available in the water. Guppies primarily feed on algae and small invertebrates.

A seashell, also known simply as a shell, is a hard, protective outer layer created by an animal that lives in the sea. The shell is part of the body of the animal. The shells are empty because the animal has died and the soft parts have been eaten by another animal or have rotted out. The term seashell usually refers to the exoskeleton of an invertebrate; it can also be used to mean the shell of various marine invertebrates.
