• Bilateral symmetry
• Body segmentation
• Endoskeleton (bony or
cartilaginous)
• Pharyngeal pouches
(present during some
stage of development)
• Complete digestive
system
• Ventral heart
• Closed blood system
• Tail (at some stage of
development)
•All vertebrates reproduce sexually, the males
reproductive cell, the sperm meets with the
female reproductive cell, the egg through
sexual intercourse.
•Vertebrates live in all areas of the world, it
is hard to pin point an exact area of their
location because they are everywhere. A
vertebrates habitat is anywhere that there
is oxygen.
•Grizzly Bears mate in the spring
time.
•When winter comes around they
hibernate.
•Bears usually give birth towards
the end of hibernation and can
give birth to more than one cub.
•Once the cub is about a year old,
it is almost fully grown.
•After 2-3 years the cub is forced
to leave by its mother and is
ready to support itself.
•Grizzly Bears are ready to mate
at the ages of 4-7
•They can live up to 30 years.
• Vertebrates have bilateral
symmetry, meaning that if you
cut them in half vertically they
would be the same or similar on
both halves.
• Vertebrates have cells, tissues,
organs, and systems.
• Vertebrates are multi-cellular,
meaning that they are made up
of more than one cell.
• Vertebrates are eukaryotes,
because they have a true
nucleus in every cell.
• All vertebrates are
heterotrophs, meaning that
they can’t make their own
food.
• They eat by consuming
food and then digesting it.
• They digest their food by
using their digestive
system, containing the
mouth, the esophagus,
stomach, liver, gall bladder,
pancreas, small intestine,
and the large intestine.
• Vertebrates have a closed circulation meaning
that the blood is closed at all times within
vessels
• Blood is pumped by a heart through vessels
• A closed circulation does not normally fill body
cavities.
• Vertebrates use aerobic respiration.
• They bring oxygen into their lungs, through their mouths and
nose and then produce waste known as carbon dioxide (CO2)
• Vertebrates have a brain and nerves.
• You can tell that they responded to
external stimuli because if you went up
and poked a bear, they would respond to
your poke.

• 1: Vertebrates are some of the smartest
species on earth.
• 2: There are five classes of vertebrates
fish, amphibians, reptiles, birds, and
mammals.
• 3: About 58,000 species of vertebrates
have been currently described.
