Yes, an endoskeleton is found in vertebrates. It is an internal skeleton made of bone and cartilage that provides support, protection for internal organs, and facilitates movement. Vertebrates, including mammals, birds, reptiles, amphibians, and fish, all possess an endoskeleton as a defining characteristic of their phylum, Chordata.
between the vertebrae
Yes. Birds, fish, and mammals always have an endoskeleton.
Echinoids have a hard endoskeleton composed of calcareous plates called ossicles, which form a rigid structure to protect their internal organs and provide support for movement and feeding.
The spine is a part of the endoskeleton.
in the spinal canal between the vertebrae.
endoskeleton
The antonym of exoskeleton is endoskeleton. An endoskeleton is an internal skeleton found in vertebrates, whereas an exoskeleton is an external skeleton found in arthropods and some other invertebrates.
Hydra do not have an endoskeleton. They are multicellular organisms that can be found in unpolluted fresh-water ponds, streams, and lakes.

Endoskeleton
Chipmunks, like all mammals, have an endoskeleton, which means their bones are internal. An exoskeleton is a hard outer covering found in arthropods like insects and crustaceans. Chipmunks do not have an exoskeleton.
Endoskeleton - their bones are inside their body
Cows have endoskeletons. An endoskeleton is found inside the body and is composed of mineralized tissues. Some sponges and symmetrical marine animals also have endoskeletons.
Arctic foxes are mammals and have internal skeletons (endoskeleton).
Transverse foramina are found in the cervical vertebrae of the spine. They are openings on the sides of these vertebrae that allow passage of the vertebral arteries and veins which supply blood to the brain.
Yes. Toucans are birds, so they have a backbone.
