Medaka Egg Presentation: Timmy By Morgan McFarland

  1. 1. How to hatch a Medaka Egg: Timmy<br />Medaka Egg Project By Morgan McFarland<br />
  2. 2. Timmy: Japanese Medaka Egg<br />As I was laid by my mother with hundreds of brothers and sisters, I rolled around in my egg.<br />I am being examined by Morgan McFarland and Alysha Bridge. <br />Its hard to tell what’s happening next except for when they talk about how I keep moving to different stages. <br />
  3. 3. Approximately 20 hours old<br />I am growing very quickly, I am moving through stages like crazy!<br />This is me at 20 hours old, this is about stage 16.<br />¾ of my yolk is covered by the blastoderm and has expanded to the equator of the yolk sphere.<br />
  4. 4. 52 Hours: Stage 24<br />I now have an early heartbeat which pulses about 40 to 60 beats per minute. <br />It’s kind of weird being in this narrow tube that is completely ventral to my head. <br />I don’t have any circulation yet though although blood islands group on my yolk. <br />
  5. 5. 74 Hours: Stage 28<br />Yay! I finally have pink blood. My heart is bent so that my ventricle is lying on my right side. <br />I am now having about 136 heart beats per minute. <br />My pink blood is pumping out of my heart through a tube. <br />
  6. 6. 102 Hours: Stage 30<br />My urinary Bladder is seen slightly. <br />My heartbeat is clearly seen with about 168 beats per minute. <br />Ouch! I think I am “jabbing” myself in the eye with the end of my tail.<br />OOOH! And I forgot to tell you, my pectoral fin is starting to move too.<br />I’m getting excited, I think I’m going to hatch soon <br />
  7. 7. 168 Hours: Stage 34<br />My heart rate is starting to slow down a little by having 124 beats per minute. <br />My jaw is slightly moving and I’m starting to turn yellow. <br />My tail is still poking me in the eye and I’m really getting irritated.<br />Also, my dorsal fin is present; but not spotted as easily.<br />
  8. 8. 200 Hours: Stage 35<br />You can see my spleen and mouth! My heart beats 136 per minute.<br />My color intensity and initial shape are variable. My liver is also seen.<br />My mouth is moving once in a while, and I have weird spots on my back.<br />My yolk sac is devoid of pigment cells and I didn’t start to hatch yet. Maybe tomorrow!!<br />I sure hope I hatch soon because I am getting sick of being squashed!<br />
  9. 9. Over 200 Hours: End of Stage 35<br />The only difference of my body from yesterday is that my spleen and other parts are getting more noticeable. <br />I had 138 heart beats per minute!<br />Everything else is the same except for I’m getting more and more anxious to get out of this egg!!<br />
  10. 10. Day 12: Stage 36<br />I was hatched!<br />My owners were so happy today when I was swimming around.<br />I was happier than they were because I was out of that crammed space in the egg! <br />I wouldn’t stop moving around, so they couldn’t examine my heartbeat. <br />
