Marine  Mammals,  Reptiles,  Amphibians  and  Birds    

What  does  it  mean  to  be  a  tetrapod?        What  three  things  were  needed  to  survive  on  land?    

•        

•        

•          

Which  two  of  these  problems  did  amphibians  NOT  figure  out?      What  does  it  mean  to  be  oviparous?      What  can  a  reptile’s  eggs  do  that  an  amphibian’s  eggs  cannot?        Which  two  types  of  animals  evolved  from  reptiles?        How  many  species  of  reptiles  are  there?  ______________________________    What  are  the  main  groups  of  reptiles?                      What  does  it  mean  to  be  an  ectotherm?        

What  can  sea  turtles  NOT  do  that  tortoises  and  turtles  can  do?    How  many  species  of  sea  turtles  are  there?  _________.    What  do  they  primarily  eat?      What  can  some  of  them  eat?      What  is  the  largest?  ________________________________________How  long  can  it  grow?  _______________                          Where  does  copulation  take  place  in  sea  turtles?      Where  and  how  does  the  mother  lay  the  eggs?          How  many  eggs  are  produced  on  average?  _________________________      How  long  will  it  take  the  eggs  to  hatch  and  why  are  they  so  vulnerable?          How  many  species  of  sea  snakes  are  there?  ____________    How  long  can  they  grow?  ______________      What  does  it  mean  to  be  ovoviparious?          Do  sea  snakes  need  to  return  to  land  to  lay  eggs?  ____________    

Why  are  sea  snakes    endangered?      Where  can  saltwater  crocodiles  be  found?          How  large  can  they  grow?  ____________feet    What  does  it  mean  to  be  an  endotherm?        How  do  seabirds  spread  waterproofing  material  around  their  body?        Seabirds  make  up  _________%  of  all  bird  species  and  eat…        But  they  must  nest  on  ____________________________      How  are  penguins  better  adapted  for  life  in  the  water  than  other  birds?        Why  can  penguins  survive  in  such  cold  conditions?        ________  of  the  18  species  live  in  the  southern  hemisphere  near  Antarctica.    One                    species  lives  as  far  north  as  the  _________________________islands.        Where  do  penguins  mate  and  lay  their  egg?        Which  parent  guards  the  egg  during  the  winter?      Why  is  the  egg  produced  in  the  winter?  

 How  do  pelicans  catch  fish?                                     What  can  be  said  about  feeding  in  seagulls?          

           

In  mammals,  where  does  the  embryo  get  it’s  nutrients  from?        How  is  the  newborn  baby  mammal  fed?        What  are  the  three  functions  of  blubber  in  marine  mammals?              What  is  a  physical  difference  between  a  seal  and  a  sea  lion?          What  are  the  distinguishing  characteristics  of  a  walrus?          How  heavy  can  a  male  walrus  get?                

                                                                                                                                         How  big  can  sea  otters  get?                 How  do  they  stay  warm?                    Why  are  they  important  to  the  kelp  forests?                    Where  can  they  be  found?      Where  are  manatees  found?        How  many  of  the  four  species  are  found  in  the  Amazon?      How  large  can  they  grow?  _______feet  and  _______________pounds.      What  do  whales  and  dolphins  NOT  have  that  fish  do?              What  do  female  whales  have  in  common  with  female  humans?        What  is  the  function  of  blubber  in  whales?          How  many  species  of  whales  live  in  salt  water?  _______    List  three  types  of  toothed  whales.    

 How  many  species  of  whales  have  teeth?  ________      What  does  it  mean  to  be  a  toothed  whale?        How  many  humans  did  killer  whales  in  the  wild  kill?  _______    What  do  baleen  whales  NOT  have?    Why  are  baleen  whales  in  such  decline?        What  do  these  large  baleen  whales  feed  on?  Why  is  that  stuff  considered  planktonic?          List  four  examples  of  baleen  whales.        What  is  a  large  group  of  whales  called?      Where  can  they  be  seen  jumping  out  of  the  water?        Why  are  so  many  dolphins  killed  in  nets?            How  fast  can  killer  and  blue  whales  swim?    How  fast  can  dolphins  swim?      How  long  can  sea  otters  dive  for?    __________________    How  deep  can  they  dive?  _________________
