invertebrates are animals which do not have a skeleton made up of bones . Some examples of invertebrates are - Jellyfish , Corals , Starfish , Sponges , Crabs and Shrimps
The skeleton is made up of bones.
They are supported by a skeleton made up of the protein collagen and spicules, which may be calcareous or siliceous, depending on the group of sponges examined. Skeletal elements, choanocytes, and other cells are imbedded in a gelatinous matrix called mesohyl or mesoglea
seahorse's skeleton is made up of bony plates
Spicules are tiny hard needles made of silica or calcium carbonate that provide structural support to the body of certain sponges. These spicules can vary in shape and size depending on the species of sponge and are often used in taxonomy to classify sponges.
Spongin provides structural support in certain marine sponges by forming a flexible, protein-based skeleton. Spicules are tiny, needle-like structures made of calcium carbonate or silica that also provide structural support and protection in sponges, as well as help deter predators.
No, the human skeleton is made up of 206 bones.
