Sit & Wait
:check: Reptiles, Frogs, fish
Hunt, Identify & Chase
:check: Time & Effort consuming

Control of food intake

:check: Hunger & Satiety control by sensor, received by hypothalamus
b. Short term Control
:check:Pressure receptor (in crop/stomach) detects esophagus/stomach is full or empty
c. Long term Control
:check: Fat deposition releases leptin to release neuropeptide to reduce food intake & increase thermogenesis & physical activity
