NEET BIOLOGY

Detailed explanation-1: -Hydrostatic skeletons are very common in invertebrates. A common example is the earthworm. Also, hydrostatic nature is common in marine life such as jelly fish and sea anemones. Earthworms have rings of muscles that are filled with fluid, making their entire body hydrostatic.

Detailed explanation-2: -Invertebrates without skeletons include centipedes, millipedes, worms, jellyfish, octopuses and squids. Because these animals have no hard bones, they are extremely flexible.

Detailed explanation-3: -Invertebrates are animals that lack a vertebral column. The skeletons of invertebrates vary, including hard exoskeleton shells, plated endoskeletons, or spicules.

Detailed explanation-4: -Jellyfish have hydrostatic skeletons Rather than a skeleton made up of bones, jellyfish have bells containing fluid and circular muscles.

Detailed explanation-5: -Hydrostatic skeletons are fluid-filled columns, or cavities, inside invertebrates, including jellyfish, flatworms, nematodes, and annelids such as earthworms.
