it is called exoskeleton
Exoskeleton.
Some animals that are soft and have no skeleton or outside shell include jellyfish, slugs, and sea cucumbers. These animals rely on other structures or mechanisms for support and movement, such as hydrostatic pressure in jellyfish and muscular contractions in slugs.
Animal life without a backbone or skeleton are called "invertebrates" like for instance; slugs, worms, jellyfish, sea anemones, starfish, octopus, squid, leeches, hag fish, and cuttlefish are all boneless animals
Animals support their bodies through skeletal structures, such as bones or exoskeletons, which provide shape and support. They also rely on muscular systems to move and maintain their body position. In addition, some animals use hydrostatic skeletons, such as fluid-filled cavities, to support their bodies and facilitate movement.
Almost all animals have a skeleton, whether its an internal skeleton or an exoskeleton. Some animals like the Jellyfish are of without a skeleton, and they are very much ... jelly-like. Examples include earthworms, slugs, etc.
A hard skeleton on the outside of some animals, known as an exoskeleton, serves multiple purposes. It provides structural support, allowing the animal to maintain its shape and protect its internal organs. Additionally, the exoskeleton acts as a barrier against predators and environmental hazards, while also preventing water loss in terrestrial environments. Examples of animals with exoskeletons include insects, crustaceans, and arachnids.
No, some animals have an external skeleton like insects and crustaceans. Others have an internal skeleton like fish and birds and people. Some internal skeletons are made of cartilage like sharks and some are made of bone and cartilage together, like mammals.
All animals have skeletons, unless they happen to be an invertebrate, such as a worm. Some animals also have exoskeletons, but that is still a type of skeleton.
Endoskeletons. Arthropods such as lobsters, insects, and shrimp have exoskeletons. Endoskeletons have a skeletal system inside thier bodies, while exoskeletons have hard outer shells.
all the bugs and some sea animals
No, a crow does not have an exoskeleton. Crows, like all birds, have an endoskeleton, which is an internal skeleton made of bones. Exoskeletons are found in some invertebrates, such as insects and crustaceans, where the skeleton is on the outside of the body. Birds have feathers and other adaptations that distinguish them from animals with exoskeletons.
