This is an attempt to list every species on exhibit at Downtown Aquarium Denver during my visit on 6-5-16. I am arranging the list by the current visitor map by the named zones as they are encountered along its one-way route. I am including species for which there is a sign on each exhibit. This is not intended to be a full account of the collection. Also, species on exhibit are sometimes moved, so some that were there one day may have disappeared from public view the next. This list may be of more interest to those already familiar with the aquarium since I am not arranging the species by animal type. It should be noted that a majority of the aquatic exhibits seemed to have unsigned species in addition to those with signs; I have listed them as 'Fish' in the exhibits that have an especially notable number of unsigned species. All exhibits are indoors. NORTH AMERICAN WILDERNESS: (10 Exhibits) These exhibits are within a large glass atrium room with highly-detailed simulated rockwork and temperate forest flora.
