== Physical characteristics == Burgessochaeta had two long tentacles on its head. The rest of the body had between 16 and 30 segments (possibly indicating multiple species). Each segment had two groups of long chaetae on it, which Burgessochaeta presumably used to swim. Burgessochaeta is not thought to have had eyes. The body grew slightly wider towards the posterior end of the animal.
