Frog Anatomy:
Organs/Body parts FunctionsAnkle Help support walking and jumping
Thigh Aids in movements
Hind legs Jumping, climbing, swimming and
digging
Foot They provide the frog a largerarea to push against water
Upper arm Helps him jump, swim, and padthrough water
Blow spot Light sensitive eyes, characteringprimitive groups of fishes andamphibians
Absence of tail Frogs don’t have tail to assist withmovement and balance
Web Helps them swim in water
Sticky fingers Aids the frog climb slippery trees
Hands Determines the frog’s sex
External nares Uses it for breathing whenswimming
Head Receives sound waves throughthe tympanic membrane
Mouth Traps insects
Tongue Catches the insects and brings itback into the mouth
Skin For protection, respiration andcan absorb water and oxygen
Tympanum Serves to equalize pressurewithin, hearing
Notes: Croaking is an sound made by frogs. frogs croak either to attract females
or to repel other males from a territory. By observing the frog’s foot, scientist have been able to create flippers.
Dichotomous Key / Organisms Identification Key
An dichotomous key is an series of question, indicating specificcharacteristics of given organisms. By following the key, you would be ableto identify the organism.
Begin here: Organism does not have an tail …….. use frog key Organism does have tail ……. use salamander key

An dichotomous key is an series of question, indicating specificcharacteristics of given organisms. By following the key, you would be able
to identify the organism. Before creating an dichotomous key, you mustobserve the different characteristics of the specimen.
