Planarians are also an emerging model organism for aging research. These animals have an apparently limitless regenerative capacity, and the asexual animals seem to maintain their telomerase levels throughout their lifetime, making them "effectively immortal".

Planarians certainly excel at it, though; a flatworm can recover from being cut up into a staggering 279 tiny pieces, each of which regenerates into a new worm!

How did nematodes get in my fish tank?
Aquarists often first come across these harmless 'white worms' when they spot them in their hundreds massing on the sides of the aquarium in newly set up aquariums during the cycle process, when the aquarium is lacking in oxygen or if the tank is heated.
