==Description== Adult specimens of Dollocaris measured over in length. It sported a row of small appendages to assist in swimming, as well as three pairs of clawed segmented legs, but it was probably a poor swimmer, instead depending on ambush to hunt prey. It is known for its well-preserved, large compound eyes, sporting well-preserved individual retinula cells, which assisted in catching prey. thumb|Fossil specimen
