No; hermit crabs sense odors using the straight pair of their antennae.
They are communicating. Crabs use their antennae to sense the world around them. By touching each other, they are finding out who is next to them and what they are doing.
Yes, hermit crabs have two pairs of antennae one for tasting and the other for smelling since hermit crabs don't have noses. The hermit crabs uses the long set of antennae for finding food, and the small short pair for tasting and eating.
The possession of two pairs of antennae is a characteristic of crustaceans, which are a diverse group of arthropods that include crabs, lobsters, and shrimp. These antennae are used for sensing the environment, detecting food, and communicating with other members of the species.
Crabs are classified as crustaceans in the order Decapoda, which means "ten-footed." They belong to the infraorder Brachyura, which includes over 6,700 species of crabs. Crabs are characterized by their exoskeleton, jointed limbs, and two pairs of antennae.
Plankton, lobsters, shrimp, crabs. If any one thinks of any more please help me!! (P.S. i hate science class!)
They have two sets of antennae, the longer set is for feeling things and the other set is like a tongue, they can taste with it, they have no tongue.
Ants are insects. Practically all normally developed insects have exactly two antennae (feelers) each, except for some of their life stages, such as eggs. All fully grown ants have two antennae each, like practically all other fully grown insects. In this they differ from say, crabs and lobsters, that have four.
crayfish have six antennae
Mollusks do not have antennae at all. Insects have antennae.
Horseshoe crabs are in subphylum Chelicerata because they have four pairs of walking legs, a pair of pedipalps, and a pair of chelicerae. Pedipalps control food, and chelicerae are pinchers that crush food. Horseshoe crabs also don't have mandibles, which are jaws, and they don't have antennae. They have two tagmata: cephalothorax and abdomen. All of these characteristics apply to organisms in subphylum Chelicerata, and so horseshoe crabs are in subphylum Chelicerata.
No, they do not have antennae.Insects have antennae. Arachnids are not insects, so they do not have antennae.
