Hi Morvarid798!

Although there are many unfamiliar words in the text you pasted, I can try to give an explanation, as I perceive it.

The sentence goes like that:
Detritus feeder - <several creatures that belong to class “Detritus feeder”>, among others <where among others? - in the class “Detritus feeder”> - work like…
Thus, word “others” refers to “Detritus feeder”, which is b:feeders

Did I make it clearer?
