Re: [PSUBS-MAILIST] What ever became of the haemosponge?

[Juergen Guerrero Kommritz <groplias2@yahoo.com>]

As far as I know the substance was a type of syntetic blood based on a Fluor compound.  It worked well with guinea pigs and mice but the problem is the flour compound is also toxic so it can only be used for a short time.
To breathe under water is not possible, the experiments with mice were very promising but the animals died of exhaustion after a while.  Water is much dense than air and our diphragma is not strong enough to move the amount of water needed to do the oxigen exchange. Water contains also much less oxigen than air.
That is what I read about this topic some years ago. I hope is usefull.
