Subject: What cold blooded organisms have enzyme catalase in them?

I have been unable to find out which cold blooded animals are 
able to catalyse the breakdown of hydrogen peroxide into water 
and oxygen so i was hopping that someone may know of some 
organisn, preferably readily available in England that is able 
to do so.  The reason i ask this is that i am going to carry out 
an investigation to determine whether the enzyme catalase has 
different resistances to temperature changes from the two chosen 
(One cold blooded and the other warm).
