The silkworm is the larva or caterpillar of the domesticated silk moth, Bombyx mori (Latin: silkworm of the mulberry tree). It is an economically important insect, being a primary producer of silk. A silkworm's preferred food is white mulberry leaves, though they may eat other mulberry species and even osage orange. Domestic silk moths are closely dependent on humans for reproduction, as a result of millennia of selective breeding.
Some flatworms mimic other animals such as nudibranchs (or perhaps visa versa). What do they eat? Many flatworms are carnivores that prey on tiny animals (protozoa, copepods, worms) or feed on immobile animals such as bryozoans, ascidians and molluscs. Being flat, they slip easily between the shells of bivalves and some flatworms are considered pests of oyster farms. Some are scavengers, feeding on dead animals.
