Transcript of Predator and Prey
Skulls and Teeth
Why Should I know about
Skulls and Teeth?
Skulls/teeth are the most
Imagine going for a hike with friends and finding an animal skull on the ground and having the knowledge to tell them what it is!
You can tell what type of
they eat based on what types of teeth they have
It is a great way of telling the
health and age
of the animal/s
Predator / Prey Characteristics
Another skull characteristic in determining what type of animal you are examining is the location of the
Predator (carnivore/omnivore) eye sockets are located in a
position on the skull providing these animals with
which gives them the ability to judge distance (depth perception).
Take a look at the following skulls and make a prediction on your note sheet whether it is a carnivore (eats meat only) or an herbivore (eats plants only)
Predators are animals that
eat other animals
Predators are always
(eat meat only, ex: tiger) or
(eat meat and vegetation, ex: black bear)
Prey are animals that are
by other animals
Prey may be carnivores, omnivores OR
(eat vegetation only, ex: deer)
When examining skulls and teeth, make sure to look for key
characteristics of a carnivore, omnivore or herbivore
The man's job in this video is to prepare skulls and skeletons for sale to museums/schools to preserve and study them.
Why is it important to understand what the differences are between different types of animal skulls and skeletons?
Prey (herbivores) eye sockets are located on
of the skull providing these animals with
, which gives these animals nearly a 360 degree field of view.
"Eyes in the front, the animal hunts. Eyes on the side, the animal hides."
Teeth Can Tell Us the Most
By examining the animal's teeth carefully, we can
whether the animal is a carnivore, herbivore, or an omnivore.
All mammals are heterodonts
Types of teeth:
Incisors - any of the four front teeth in each jaw, used for
Canines - long, pointed teeth used for
and holding prey.
Molars and Pre-molars - used for grinding and
, molars, pre-molars, small incisors
Molars and pre-molars overlap, like scissors, creating a shearing action. These teeth are called
Herbivores: large incisors, tiny canines that act more like incisors, grinding molars and pre-molars.
on upper law
Omnivores: large canines, large incisors, carnassial pre-molars,
(for grinding) molars
of carnivore and herbivore teeth
How do teeth help us identify a random skull found in the forest?
Young deer teeth
Old deer teeth
