Do all animals (including fish, insects, worms ect.) have a tounge?

Answer 1

Not all animals have more than one cell. However, most multicellular animals do have a digestive system which may have 1 or more openings. Most of the "more" evolved species of animals on this planet do have specialized mouthparts for the manipulation of food material, but not all. If you mean more along the lines of a fleshy, muscular protuberance from the mandible into the mouth cavity, than your scope is rather limited at least relatively speaking. One could consider the radula of mollusks to fit this definition even though it is usually also covered with chitinous "teeth".

Answer 2

VERTEBRATES have tongue but other animals having some taste buds ontheir diff.part of body.like fish can taste water whether it is fresh water or marine water by its outer skin.cos they have some sensitive site on their skin
from protozoan to chordates the taste organ changes frm immature stage to mature stage as tongue
in case of human being the r 5 taste bud to detect diff taste like sweet,sour.salty etc..but lower animals dont have any taste buds

Answer 3

No, definitely not. Vertebrates have tongues (mammals, birds, amphibians, reptiles, fish)

No tongues for arthropods, mollusks, echinoderms, worms, cnidarians, sponges, or any other invertebrates that I can think of.
