  1. Japanese Medaka(Stauvros) By Seth Spack and Quint Weber

  2. Day 1 • On this day we had begun our lives with Stauvros. He lived in a container with water along with Jake and Dane’s Lil’ Ko-Jo. Every day we had to change his water so he could live in a fresh environment. The first time we sucked him up through the pipette we felt a connection. The yolk which holds food for the embryowas visible. Stauvros did not have a heart beat on day 1 .

  3. Day 2 • Stauvros must have been a quickly developed egg because he had a heart beat of 94 on day 2. We were so proud of him. We figured he was between stage 25 and 26. The tip of the tail was free from the yolk sac. Stauvros’ eyes also started to form so he could start to see the world around him.

  4. Day 3 • Stauvros’ heart beat rose by almost 30 beats on this day. He was in stage 28. After we put him on a slide we observed him. Then we switch his water so he stay alive. Some features we saw were that he had a blood flow which carries oxygen throughout his body so he can breathe. The tail had also lengthened.

  5. Day 6 • We did not get to see Stauvros over the weekend. We felt bad because he was all alone and had nobody to talk to. His heart beat had rose to 131 beat and he was in stage 31. We notice that Stauvros had some fin movement and twitched a bit. His retina pigment was very dark and he had big black eyes.

  6. Day 7 Stauvros is getting very developed now. He is at stage 34 and has a heart beat of 168. He is about eight days old here. We are waiting for him to hatch. There was some jaw movement and eyes movement. The jaw movement indicated that it will have a functional mouth when is grows up. The dorsal fin was present and when develop will be used to swim with.His tail, another swimming limb, was reaching the back of the hindbrain.

  7. Day 8 • We are almost ready for the arrival of the hatching of Stauvros. Features that he had we a very viewable blood vessel which carries oxygen throughout his body and you could see his mouth which was under his eyes. Stauvros was in his final stages before hatching. The next day we see him he will be a new man.

  8. Hatching • This is Stauvros when he hatched. When he looked up at us we just smiled back. Features that Stauvros had was a tail, caudal fin, pectoral fin and dorsal fin that all help him swim. His egg was still left behind in the water. He had grown so much in so little time. We were very proud. Unfortunately, we could not afford the cost of child support and we had to put Stauvros up for adoption. Jeremy Neese had adopted him. That is the life of Stauvros.
