Sexual S. Mediterranea Laying Egg
Sexual S. mediterranea are hermaphrodites that cross-fertilize. This movie shows a pregant worm laying an egg capsule; a single capsule can contain multiple embryos.
Hydra regeneration
This movie shows a regenerating hydra. If hydras would be huge, they would be really scary monsters - as in the Greek mythology.
Asexual reproduction
Fission in asexual S. mediterranea. The entire movie is ~60min long. Interesting are the two phases of elongation before division occurs.
Gliding Planarians
Freshwater planarians move in a straight gliding motion using cilia at the ventral side beating in a layer of mucus.
S. Mediterranea hunting artemia
This little planarian fights hard for his prey - all good things are three also seems to hold in the planarian world!
S. Mediterranea Eating Liver
Our planarians are spoiled: They only eat organic liver pate. For a protocol of how to make this liver paste, see our protocols site.
