Not all animals with antennae are arthropods, although antennae are a characteristic feature of this group. Antennae are sensory structures found in various animal phyla, including some mollusks and certain annelids. However, the presence of antennae is most commonly associated with arthropods, such as insects, crustaceans, and arachnids. Thus, while many animals with antennae are indeed arthropods, they are not exclusively so.
Chelicerata is the subphylum of arthropods that is characterized by animals lacking antennae. This subphylum includes arachnids like spiders, scorpions, and ticks.
The subphyla of arthropoda that does not have antennae is chelicerata. Chelicerates, which include spiders and scorpions, are missing the first segment of nerve ganglion which controls antennae in other arthropods.
Some animals that live in freshwater and have antennae include freshwater shrimp, freshwater crayfish, and water beetles. These antennae help them sense their surroundings, locate food, and communicate with other members of their species.
There are quite a few animals that antennas and shells. Most of these animals are in fact insects that fly.
