Bio Bottle Project

By: Bryce, Katelyn, and Alivia


In the beginning of this project our group thought all of our organisms would stay alive and that our bottle would be an accomplishment. This project is a great learning experience! Go through our presentation and learn about what our bottle was like!

Tubifex Worm: What is this creature's niche?

  • Tubifex are annelids
  • Freshwater worms
  • Red color because of haemoglobin in their bodies to allow them to survive in oxygen lacking places
  • Have bristles on their sides to provide traction
  • They eat very nasty decay and horrible stuff humans try to avoid

Habitat Requirements

  • Live in mud, sludge, and sewage
  • Thrive in nasty, stinking lakes and rivers

Fun Facts

  1. If there's no slimy surface to cling on to...they cling to each other! Becoming a mass of squirmy nastiness.
  2. They also are hermaphrodites and can fertilise themselves!
  3. These little worms are used as fishing bait and fish food
  4. In North Carolina the worm is referred to as the "Carolina poop monster"

Observations Of Our Bottle

Day 1: ​All living animals are alive. We had found animals like a tubifex worm, a hydra that was

starting to reproduce, and an orb snail. We also had many many water boat man swimming


Day 2: ​We still have all of our animals that I mentioned before plus we found another small

hydra and the original hydra was starting to grow bigger and the new baby was growing bigger

on the side of the hydra.

Day 3: ​We then found more water boatman, and some new water fleas and some daphnia. We

could no longer see our orb snail, so we are thinking that it has died.

Day 4: ​We couldn’t find our second small hydra and the original hydra was still growing its baby

on its side. Our tubifex worm is still wiggling around and a live, and our water boatman's, and

some of our water fleas are still swimming around, but not as many as there were in the


Day 5: ​We found a flatworm, that was making its way down the bottle. Along with that we saw

our hydra’s baby on the side of it get bigger than what is was before.

Day 6: ​We saw that we had a damselfly larvae in our bottle that was flying around and then

crawling on the side of the bottle. We also saw that we had a second damselfly larvae but it had


Day 7: ​We came to the conclusion that our second damselfly had been eaten by our tubifex

worm, the scale was floating at the top connected to the tubifex worms habitat.

Day 8: ​We could no longer find any of our hydras on the side of the bottle, and when looking for

them we found our snail that we thought was dead. We also found one more flatworm next to

the original one at the bottom of the bottle hidden in the top of the soil.

Day 9: ​We found 3 flatworms in the soil crawling around. Our original damselfly was dead as

well. Our tubifex worm had died as well, but our re­found snail was crawling on the side of the


Day 10: ​The only thing left in our bottle was the snail, one flatworm was at the bottom the bottle.

And the water boatman were still swimming, and water fleas.


We predict that the hydra will stay alive the longest. We also predict that if the hydra does die, it will cause everything else to die as well because it is very important. We predict that the worms will die very fast because the hydra eats worms. We predict that there snail will die early on because it does not have a lot of food to eat.


In the end everything in our bottle died out. We still aren't positive why that is, and why other group's experiments turned out a lot better than ours. With this experiment you learn to observe and be patient. We got to see for ourselves how a ecosystem works and how it can evolve.
