Vertabrates digestion vs invertebrates digestion

[fonsy]

Hey, I had to do a presentation about the digestive system for school and I was supposed to compare vertebrates digestion and invertebrates digestion but I cant seem to find any information that compares the two.. So far i just wrote that invertebrates digestion can be intracellular or extracellular and vertebrates digestion is only extracellular..(at least its most important digestion is extracellular, right?). Anyway, hope someone can help me out since I have to finish it by monday. Thanks.

Pick a couple of sample species and compare them. Suggestions:

Hydra, bacteria, sponge, venus fly trap, earthworm.

bacteria and venus fly trap aren't invertebrates

Thats what i thought...

The main problem is that for most realms, the term "invertebrate" is useless, dating back to Victorian times - there are far too many different types to lump them altogether for system purposes.

Hehe, but they don't have backbones

@darby
I tend to agree. But you have to clasify them based on something... And there are some main differences between them, based on molecular development as well as morphology
