      For my bio class i need to catch and make a two headed planaria, which has proven extremely difficult so far.

      quick few questions for anyone who has any information:

      1. How do i catch planaria? Teacher told us to use chicken liver… but where do i put it in the pond? on the surface or toward the bottom? Also what kind of pond is the best place to look for them, im in san jose california if anyone has any real specific spots in that area it would be awsome.

      2. To make a two-headed planaria i stick them on a paper towel then i put them over ice, the problem i am having is that after i cut the planaria the heads refuse together and regenerate into one single head again.. anyone have any tips? any help would be great thanks so much.

      😛

      1. Place several chicken livers in the most active pond you can find…put each chicken liver at a different depth, light concentration, etc.

      2. Continue cutting the split head at the fusing point until it ceases to fuse back together.

      Two-headed planaria? Is this possible? Please do tell me more about how this is done, if you are so kind

      Well, planaria can regenerate, and their ganglia is kind of split into two different parts at the posterior end. So if you cut down the middle of that (maybe you need to cut a little farther down) two heads will grow. It’s also possible to cut off it’s head, and it will regrow a head on one side and a tail on the other creating two planaria, you can also give it two tails and so on.

      How do you go about actually catch the planaria? Do you put the Chicken Livers in something or are they fully exposed to any and all inhabitants in the pond?

      Planaria inhabits clear, cold fresh water on shaded area. It prefers slowly flowing water-body e.g. stream.

      Tips to fish Planaria:
      – Tie some fresh liver (not only fron chicken but can be from anything) as a bait on your rope tip.
      – Then leave your "special Planarian fishing rod" for some minutes. Tie the rope on something just like a cowboy tie his horse bridle so you won’t lose it.
      – Check whether you already got your Planaria. They will attach on your bait.
      – To remove them from your bait, dip the liver on a jar contains local water, shake it gently, they will detach. Don’t use tweezers, they wil hurt our delicate lovely creatures 😉
      – To take care of them, keep the temperature of the water or they will be dying. You can keep them in clean refrigerator but avoid sharp smells around them coz they don’t like it.

      The thing about liver, I think, is that it’s "juicy," and the planaria will pick up the "smaell" and track it to its source. They climb on it, extend their pharynx and as long as the meat moves gently, stay on it feeding.

      you could use a planaria trap with a little piece of meat or fish as bait.

      Very good results were achieved by using frozen bloodworms as these are highly attractive to planaria.

      There are lots of experiments you can do with planaria without cutting them up! Light sensitivity, what is their favourite smell? colour of substrate, how strong must the temptation be to make them cross a white line etc. The best thing is if you colour spot individuals, and find that some like to do one thing and others don’t.
