This may be the dumbest question ever, but I'll ask anyways. Do insects and spiders breathe? Or I guess I should ask if they need oxygen to survive

I do believe that most insects (arachnids included) breathe through the pores in their skins.

Yeah, but they do not breathe like us. They have either gills, gill like openings or trachea which are tubes that have openings that lead to the outside.

I think it's interesting, breathing through pores seems like a much more effective and safe way to do it.. us humans only have 2 holes and 1 tube to breathe through. Seems inefficient and dangerous

every living thing does my friend

actually there are plenty of organisms that don't require oxygen.

I like how I am actually learning interesting things here.

oh that's true.. but insects and spiders still require oxygen nonetheless
User avatar #15 to #14 - shazmothree (12/16/2012) [-]
But do they have some sort of lung like organ or do they just do something like absorb it through their skin?
User avatar #16 to #15 - themastertroller (12/16/2012) [-]
they have tracheae rather than lungs which carry oxygen throughout their bodies through pores on their skins

Oh ok
