mollusks :)
Mollusks have a mantle, which is a thin layer of tissue that covers their body and secretes the shell in shelled mollusks. The mantle plays a key role in respiration, excretion, and shell formation in mollusks.
Echinoderms :)
Snails and slugs are a smaller group of invertebrates known as gastropods. They have a soft body, usually protected by a shell, and move by producing mucus to glide along surfaces. The majority of gastropods are marine, but some are also found in freshwater and terrestrial habitats.
Living things without a backbone are classified as invertebrates. This group includes a wide range of organisms such as insects, worms, jellyfish, and mollusks. Invertebrates make up the majority of animal species on Earth.
No, it is not true that geologists group the crust and uppermost mantle into a single layer called the mesosphere. Instead, the crust and the uppermost mantle are collectively referred to as the lithosphere. The mesosphere, on the other hand, typically refers to a deeper layer of the Earth's mantle, located beneath the asthenosphere and extending to the outer core.

Worms make up the largest group of complex invertebrates.
Invertebrates do not have backbones.Examples of invertebrates are earthworms,insects,squids etc... Invertebrates are paraphyletic group.
Crustacean
Animals that have no backbone are part of the group known as invertebrates. This group includes organisms such as insects, worms, snails, and jellyfish. Invertebrates make up the majority of animal species on Earth.
Answer = Arachnids!
animals with backbones
Beetles are invertebrates
aracinaids
No, they are not. Vertebrates have vertebra, which are the bones in the spinal column. Arthropods are a group of animals that have no backbone but what's called an exoskeleton. a 'skeleton' outside the body like a shell.No they are invertebrates under the group ArthropodaArthropods are invertebrates
