👉 Thelosia is a term used in the context of the phylum Echinodermata, which includes jellyfish, starfish, and other aquatic animals that are characterized by their unique ability to change color or shape based on the light they encounter. It refers to the phenomenon where these creatures can absorb different wavelengths of light at different times of day, allowing them to manipulate their appearance to blend into their surroundings, or to create illusions in their environment.
