Question

sea slugs
by melissa ambrovitz

1. imagine eating a purple grape and turning purple! if you were a sea slug, that’s exactly what would happen. actually, sea slugs gravitate towards foods such as sea anemones, hydroids, sponges, and jellyfish, but if one of the morsels they devour happens to be purple, or some other color, the slug will automatically change to that hue.
2. sea slugs store the pigments from their food in specialized cells called chromatophores. changes in the shapes and sizes of the cells cause the sea slugs to change color. camouflaged, the slug can crawl around on its favorite food without being detected by enemies.
