Transcript of Snow Leopard

Snow Leopard
Body Systems
Embryology and Development
-Blastopore opening becomes anus.
-Radial cleveage in first cell division.
-Different DNA/RNA
Chrodate: Sub Phylum Vertebrata
-"Gill slits" at some time in their life.
-Dorsal nerve cord
-Post-anal cord
: completely covered with long thick fur (12 cm long/ thicker during fall and winter).
-Long and thick fur.
-Both in paws and tail to
adapt to cold weather
: wide to walk on snow and furry for grip and
minimizes heat loss
Flexible and long for stability. It is fatty and furry for
retaining heat
: Round and small to
minimizes heat loss
: big nasal cavity for low oxygen
- (Vibrissae) very sensitive to touch and more aware of surrounding. Located on face, under the chin and wrists.
-Retractable, sharp and curved used for climbing and protection
-Extremely adapted to consume their prey and tearing meat
Articulated Jaw
Movable Tongue
: papillae= rasp meat and grooming
Specialized Teeth
: thecodont and heterodont
-Incisors, canines, pre-molars, and molars
Digestive System
-Swallows food in chunks
-Pointed molars
-Have carnassial teeth
2. Esophagus
3. Stomach
4.Duodenum, Liver, & Pancreas
-Secretion of bile and enzymes
5. Small Intestines
6. Large Intestines

Excretory System
1. Kidneys
-Empties waste
2. Ureters
-Delivers urine from kidney to bladder

Sweat glands are
part of their excretory system
Like humans, female urethra does not flow through sex organs, whereas male urethra does.

to mammalian reproductive systems.
Breeding period
January and March
Gestation period is between
90 to 100 days
Liters of up to 3 or 4 cubs
Female leopards have a
hidden birthing den
Body is 3 to 4.75 feet long
Tail as long as the body
-Maintain balance in steep mountains

Large hind limbs with short fore limbs
-Can leap up to 45 feet
Well-developed chest

-For better muscle attachment
Adaptation to mountain life
-Tail, limbs , chest

Closed Circulatory System
4 chambered heart
-2 atria, 2 ventricles
Atrial Contraction
-Both Atria
contract at the same time
when blood has been filled
Ventral Contraction
-Both Ventricles
contract at the same time
and push the blood to the lungs and the rest of the body

Wide, short nasal cavity
-To warm the air inhaled before it reaches the lungs
-Adaptation to the cold mountain habitat
Breathe through
respiratory organ

-Increase surface area
the body
Increase pressure changes
Negative Pressure Breathing

Strong upper body strength
chest and shoulder muscles for climbing steep cliffs and hunting prey.
Adaptation of upper body strength
to its environment.
-Can jump a distance from 45 ft. to another ledge.
Muscular Tail
-Their muscular tail makes them
as it can grow to the same length as their body.
-Provides support and balance to their stature.


Appendicular Muscles
-Uses their limbs for
motility, support and locomotion
Abductor and Adductor muscle
: is used to
limbs to jump and
when they land.
Terrestrial Locomotion
: enables snow leopards to
run, climb and jump
through their surroundings.
to jump
nearly 50 ft in the air with their powerful muscular hind legs.
: Able
to climb
up rough and rigid areas (specifically mountains and cliffs). Their strong developed pectoral muscles enable them to climb in various conditions in their habitat.
Muscles Continued...
Video: How a Snow Leopard Jumps
Nervous system is located in front of their head
Central Nervous System (CNS)
: where sensory details are processed and integrated between the brain and spinal cord.
Occupies most of the space of the frontal brain. Cerebrum has 2 hemispheres that attach together through corpus callosum. It is the
integration of motor, sensory and higher mental functions
Olfactory Bulb:
Anterior end of the olfactory tract which is located in the nasal cavity. This allows the cranial nerves to
trigger the origin of the smell.

Optic Lobe:
Part of the mid-brain that uses the
sense of seeing through primary visual centers

Example: Snow Leopards uses their sensory organs (such as the sense of smell and sight) to determine if there is prey around their area. It can use a higher level of thinking to absorb the senses in an effect of capturing the prey.
Nervous System Continued...
located at the back part of the brain. Its function is to integrate the coordination and regulation of muscular activity.

Ex: When snow leopards are ready to attack the cerebellum is used to regulate and control their muscle contraction which can make them run, jump, and climb faster or higher.

Medulla Oblongata
: it is the base of the brain supported by the spinal cord. It’s responsible of involuntary functions (breathing, blood flow, etc.)
Spinal Cord:
It is an important column of nerve tissue that works together with the brain in the central nervous system. The spinal cord transmit nerve impulses to and from the brain.

Fun Facts
About Their Adaptation
Huge Paws
-Good for walking through snow
Small Ears
-Used to blend in stones/surrounding of mountains and cliffs
-Their nostrils are very deep due to the high elevation, where there is a minimal amount of oxygen
-Their tail is very fluffy and thick because it is very muscular as a counter balance when chasing prey up and down the mountain and steep inclines
Challenge: Find the Snow Leopard
Their adaptation of being able to camouflage makes it easier for them to survive in their environment.
There it is!
