I heard that fleas don't have liver, so who plays the role of liver?

A. 1

Yes. As you know, fleas don't have liver.
The enzyme in the flea blood acts as the liver.

OK

A. 2

Not only fleas, but other insects have no livers.
For the role of the liver, fat in the body, digestive tract, and enzymes in the blood are in charge.
Some of it is done in the corpus callosum, which corresponds to the kidneys.
