Just saw a documentairy on the BBC2 TV, I droped in late so I'm not sure of its title.
Some intresting notes, as those creatures can remind also to simple looking life forms reminding me of darwin bots..
* It seams that around the world jellyfish populations strongly grow.
The trigger of it why (global warming?/ chemical level changes in sea water? / ...) isnt known.
* They where in the serie afraid that it might gonna be a too blooming population.
Which could easily outnumber and kill other sea animals
* As it was fasinating, they are simple dough verry advanced 'products' of 1 miljard year of evolution.
They lack a brain, but can have 8 eyes (or more) who can focus.. [ darwin bot uses 9 eyes ]
* Their poison can be so strong, some 1 inch jellyfish can kill easily a human.
Those used to live in tropical water, but are now sometimes at the coast of England too.
* One huge type is swarming at an asian see, so bad that local fisherman catch almost no fish.
They tried to use razor nets to kill them.. but gues what.. For this jellyfish dead ment release all your sperm/eggs.
So the nets actualy spurted growth by getting them all together, for a reproduction act..
* Even more intresting is their life cycle (altough I knew that allready), they start life like a veggy plant.
layer upon layer upon layers, they grow up, cloning themselves. Until suddenly they seperate in individual jellyfish.
* Did you knew that the "portugese man o' war" jelly fish forms groups in wich individuals specialize as organs for the group? [could we simulate that?]
* some have life span that can be endless, they can become plants again in the end and start all over. [ darwin bots can live forever too ]
