I got this question in a Biology past paper and tried to find the answer on the internet too, so i thought i best answer it for other people :P
i settled with the species are so small that they have a large surface area to volume ratio, meaning they take in quite a lot of oxygen, and because they're so small they don't use up all of this oxygen as quickly as lugworms and other larger species of annelids.
if it's wrong, sorry, i basically just took knowledge and made a logical guess
A ventilation system is needed in order to obtain oxygen for living organisms and to get rid of carbon dioxide. Surface diffusion utilized by many smaller organisms is not sufficient in supplying the oxygen needs of the body. It is also needed to maintain a concentration gradient in the alveoli.

Our body obtain oxygen to our body by breathing.
Crustaceans obtain oxygen through gills.
They get oxygen from their gills.
It is because at high altitudes the oxygen is not sufficient..........
i think that, because they're so small, they only rely on a network of trachea, tracheoles and spiracles to supply oxygen - as their small bodies provide a short difusion pathway.i think
Who is "they" ?
you obtain oxygen from your lungs you could breath through your nose and through your mouth
multicellular organisms obtain their oxygen through the respiratory system
We obtain oxygen by breathing in fresh air. Carbon dioxide comes out of us.
No. The skeleton dose not get oxygen
