Other Important Structures

Front 1

reptilian adaptation
skin with scales

Back 1

keratin-the scales are filled with this protein
-skin contains additional proteins and lipids for waterproofing

Front 2

reptilian adaptation
efficient respiratory/excretory system

Back 2

-internal
-excrete uric acid, in excretory sys
-advantage to being released as uric acid-water cons
-urine concentration is very high to reduce water loss

Front 3

reptilian adaptation
hearing

Back 3

tempanon- ear drum(except in snake, lower jaw is used to pick up vibrations of the substrate)

Front 4

reptilian adaptation
olfaction

Back 4

jacobsons organ- has to do with olfaction, flicking tongue...roof of mouth...holes...then to this organ
-smell

Front 5

reptilian adaptation
heat sensor

Back 5

facial pit-vipers, water mocosins
-found primarily in snakes, very sensitive heat sensing organ found under eye
-labial pit(constrictors)

Front 6

reptilian adaptation
ectothermic

Back 6

refering from where the heat source comes from, the enviroment
-poikilotherm-organism whose body temp varies, with the enviroment

Front 7

reptilian adaptation
reproduction

Back 7

oviparity
ovoviviparity
viviparity

Front 8

reptilian adaptation
parental care

Back 8

most none
-some exceptions-alligators
-when babies hatch mom brings them to the water
