    Hey Mr. Anderson, I thought Sponges and other organisms in phylum Porifera were sessile. But you are saying that all animals are motile? Which one is correct

  2. Saihla May 29, 2012 at 3:09 am

    Anyone else notice the Penis Worm on the map at 0:24???

  3. Ronnie Antony May 30, 2012 at 12:51 pm

    Thanks Mr.Andersen .You've done a great job ,but I think more people could watch your videos if you put subtitles in English.

  6. azza sarfraz February 27, 2013 at 3:50 pm

    and invertebrate evolution !!!!!!!!
    from MADER BIOLOGY *.*

  7. Aubrey Roland March 11, 2013 at 2:35 am

    sponges are motile? how

  8. nflsbest26 April 6, 2013 at 5:54 pm

    I am pretty sure echinoderms are radially symmetrical…

  9. Jonatan Mendoza April 15, 2013 at 10:44 pm

    In larva stages

  10. Andrew S June 9, 2013 at 4:41 am

    You forgot pseudocoelmates but you are the so helpful!

  11. abongile mboto August 11, 2013 at 9:02 pm

    Mr Andersen, you are amazing!!! bozemanbiology is my go to place for my biology module:)

  12. Christian Wong August 14, 2013 at 3:17 pm

    nice wallpaper behind you! Mr.Anderson 😀

  13. guitar19jeu September 18, 2013 at 6:23 pm

    0:37 amoebas …lol does anybody remembers the amoebas boys from powerpuff girls

  14. CentauriGamerz September 25, 2013 at 11:06 am

    Amoebas dont have a spinal cord. They only have a notochord.

  15. CentauriGamerz September 25, 2013 at 11:06 am

    Not amoebas. My bad. Lamcelets.

  16. CentauriGamerz September 25, 2013 at 11:16 am

    Nice video. But lancelet is not a vertebrate. It is a cephalchordate.

  17. soo won Choi October 30, 2013 at 12:38 pm

    Nice video. I hope my teacher gonna be like you ….

  18. Alicia Halhed March 5, 2014 at 2:05 am

    Love these videos! My bio teacher referred my class to your videos, since the AP curriculum is close to identical to the 11U curriculum (the Canadian curriculum in Ontario). She told us that she has based some of her lesson plans off these videos and it's super helpful just to reinforce the lesson with the video.

  19. Mohammed ABDUL MALLIK June 12, 2014 at 7:01 pm

    Awesome vedio to learn kingdom animalia

  20. Young Chase July 25, 2014 at 3:22 am

  22. Indrani kailas November 30, 2014 at 6:07 am

    I love these videos as a senior teacher!

  23. Boba Sbeity December 1, 2014 at 10:45 am

    I'm in love with your videos .. you are Brilliant !!!

  24. Michael Smith December 3, 2014 at 7:59 pm

    Gee thanks!!!!!!!!  Now my stupid biology teacher is making me right assignments on this crap and trying to force it on me.  

  25. Maryam Bouhraoua February 4, 2015 at 2:49 am

    Gosh! Didn't know we were a bunch of assholes!

  26. Adithya Sunil February 17, 2015 at 6:56 pm

  28. Setya Wibawa May 24, 2015 at 3:05 am

    Is there any link to the classification diagram on 0:40?

  29. Vishruth Hv September 10, 2015 at 11:32 am


  30. vaisshnavalaksmi srinivasan October 2, 2015 at 6:18 am

    U r an animal too!!

  31. batoul elhallani December 2, 2015 at 8:26 pm

    could you remove the captions please? they block out some info that are displayed

  32. Allen Binger February 2, 2016 at 6:25 am

    first off, thank you Mr. Anderson for these videos. second, THIS is the way we should learn, im interested, i can rewind when i miss something, i can pause and come back later, i can ask you or the comments if i have questions, school needs to be just a room full of computers. i could have read this from a book, yea, but i gotta buy the 80$ book, go get it, find the chapter i want, and then skim over until i find the info i need. OR…….. google mr anderson and find his awesome videos.

  33. Jasmine Meyer March 4, 2016 at 5:56 am

    Thank u so much u helped me study for my test so much

  34. TominatorTheGamer May 2, 2016 at 4:24 pm

    Great video once again Mr. Bozeman! You never fail to amaze me!

  35. _NIN_MOI_ May 8, 2016 at 6:15 pm

    He says "Uhh" and "Umm" way too much

  36. maddie alexandra May 9, 2016 at 11:13 am

    When you have an AP bio exam in less than an hour and your class didn't go through the last 4 units 🙃

  37. Funtime Foxy September 21, 2016 at 2:10 am

    2/10 on a test I had a chance to take a retake on it. I watch this and I got 10/10 :D.

  38. Quinn Griffin November 15, 2016 at 9:46 pm

    this is awesome and Mr. Anderson is so cute xD

  39. Tarin November 17, 2016 at 1:13 pm

    You are the best

  40. MooMoo Math and Science December 12, 2016 at 11:43 am

    You know your Science. Helpful video Thanks

  41. Cristian Jorge A. Kusch January 10, 2017 at 12:57 pm

    if you think you are your body then you are an animal

  42. insect illuminati Get shrekt January 21, 2017 at 11:46 pm

    The celeomate-aceleomate split is outdated. Protostomes are split into ecdysozoa/spiralia

  43. insect illuminati Get shrekt January 21, 2017 at 11:47 pm

    Also, why do the chordates get their own in depth look but not the other animal groups?

  44. Ed Thoreum May 7, 2017 at 2:59 am

    great job,thanks!
    how about a video on the arthropods(80% of fauna?) heads, a problem related to their ancestors basal animals?

  45. laurel sketch May 10, 2017 at 5:43 pm

    3:46 IT'S MARCO!!!

  46. Nesslig 20 June 24, 2017 at 5:27 pm

    2:15 The first animals appeared way earlier than that. Fossils of animals go back in the Ediacaran, and there is evidence for animals originating over 600 million years ago.

  47. Mewkaryote16 Allen August 7, 2017 at 1:54 am

    So chordates start thier lives as butts. ok I started my life as a butt.

  48. LIL SAVAGE September 4, 2017 at 8:46 am

    i am just in nine grade and i felt that i am almost graduating collage!! WOW

  49. Guguloth Narayana October 9, 2017 at 3:54 pm

  54. A La Ru Ru Nini A La Ru Ru Ya October 21, 2018 at 3:40 am

    Thank you for making these videos, they help a lot⭐

  55. Nin kwankaw December 4, 2018 at 12:54 am

    Do both deuterostomes and protostomes have some type of coelomate?

  56. VampireDucks January 3, 2019 at 1:48 am

    Great vid, again

  57. Gunslinger February 14, 2019 at 6:31 pm

    Anytime I'm being told I'm an animal I automatically disregard my source. Information like that is trash. Edit: Why the heck are humans classified as invertebrates??? Last I checked, I have a spinal cord…..

  58. Salah Haddad February 20, 2019 at 5:33 pm

    Are you saying that the only deuterostomes are chordates and echinoderms at 4:50?

  59. Max Power February 27, 2019 at 3:22 am

    The dislikes are teachers and professors who want to keep their jobs.
