The bones themselves are NOT, but the whole spine is.
No the leeches are not vertebrates . Vertebrates are animals that have backbones. The backbone is a strong but flexible column of individual bony unit called vertebrae.
Notochords are important to vertebrates because it forms the main support of the body. A notochord is a flexible rod-like structure.
Internal skeleton (back bone) has an notochord to make it flexible
Vertebrates belong to the phylum Chordata. This phylum includes organisms with a notochord (flexible rod) at some stage in their development, as well as a dorsal nerve cord and pharyngeal slits. Vertebrates are characterized by having a vertebral column, which gives them their name.
Yes, lions, like all vertebrates, have a notochord. The notochord is a flexible rod-like structure present in the early stages of embryonic development that provides support for the developing spine.
The difference between the major phyla of vertebrates include chordates possess a hollow dorsal nerve tube, flexible rod-like axial skeletal structure, have gill slits or pharyngeal clefts and a tail
Vertebrates do not have cell walls. Unlike plants, fungi, and some prokaryotes, vertebrate cells have a flexible plasma membrane that surrounds the cell. This membrane allows for greater mobility and interaction with the environment, which is crucial for the complex functions of vertebrate tissues and organs.
As owls are vertebrates - yes they have a back bone / spineYes, and its cervical vertebrae is long and flexible.
Snakes are vertebrates.
Yes, all vertebrates have a backbone. Birds are unusual because they have very flexible necks (usually), which is important for preening (they don't have hands or paws, and feathers require upkeep), but for energy-efficient flight they need perfectly rigid backs, so their mid/lower spine is rigid, and the upper spine highly flexible. You can explore this yourself during Thanksgiving. :-)
vertebrates
No mongoose have spinal cords, but they are so flexible it's almost not there.
