Creature Study (Reptile)

Reptile: turtle, snake, lizard, crocodile

Turtle:
The diagonal feet move almost simultaneously, with the front feet slightly faster than the hind feet. The head stays mostly still, held up, only turning to look in the desired direction. The tail also remains largely still. The front feet move first; the hind feet barely leave the ground and quickly follow. The lower body stays close to the ground, propped up by the front feet.
When swimming, it relies mainly on the front feet for paddling; the hind feet seem to only participate in turning.
The larger the turtle, the slower its movements.

Lizard & Crocodile: (this seems to be the main focus)
The diagonal feet move almost simultaneously, with little noticeable difference between front and hind feet — though the hind feet might lift just a tiny fraction slower. The body twists with a wide range of motion, forming an S-shape. The tail acts as a huge follow-through.
They can stand up and run — it looks hilarious, with their legs swinging in circles. It feels like the wild running seen in cartoons was modeled after lizards. This could probably fill its own page.
The smaller the body, the faster the movement.

Crocodile swimming:
It mainly propels itself forward with its tail; the limbs stay mostly still, only moving when turning or grabbing onto something.

Crocodile running:
It’s actually quite similar to a leopard — a fast forward leap.

Snake:
Undulatory movement — they send a wave down their body and move forward.

Pre-structure notes:

• Group turtle, lizard, and crocodile together — cover walking, running, and swimming separately
• Snake as a separate section — maybe divide into movement and stillness?
• Should we add some more cartoonish, animated-style performance or keep it completely realistic?

Creature animation in general

Animal Leg Types

• Plantigrade – The whole foot (sole) touches the ground.
  Examples: humans, bears, rabbits, raccoons, kangaroos, etc.
• Digitigrade – Only the toes touch the ground; the heel is lifted.
  Examples: cats, dogs, birds, dinosaurs, etc.
• Unguligrade – Only the tips of the hooves touch the ground.
  Examples: horses, cows, deer, and other hoofed animals.

Structural Differences Between Herbivores and Carnivores

Body shape

• Herbivore: huge rib cage, heavy body
• Carnivore: slim, agile body

• Spine
  • Herbivore: rigid
  • Carnivore: flexible
• Main function
  • Herbivore: store food
  • Carnivore: hunt

Gait Study

Using the Icelandic horse as an example, demonstrating 5 gaits.

• Emphasize observing the spine curve in side view and top view.
• The spine curve affects the movement relationship between the chest, hips, and head.

Anatomy Key Points

• The structure of the scapula (shoulder blade) and wings is crucial for flight or forelimb movement.
• Anatomy study should serve animation performance, not pure medical anatomy.
