CHARACTERISTICS OF VERTEBRATES

CHARACTERISTICS OF VERTEBRATES:

Bees are important in pollination i.e. in production of honey

Members of the phylum have a notochord in early stages of development.
They have visceral clefts – which are slits perforating the body wall at the pharynx.
In fish these slits become gills while in higher chordates these slits are only present in embryo.
They have a dorsal, hollow nerve cord.
It develops into a brain at the anterior and spinal cord at the posterior end.
The spinal cord is enclosed within the vertebral column.
