Tennessee Aquarium, Chattanooga, Tennessee (Part III)

In the River Journey building, you start your tour in the lower levels where there is a wonderful display of seahorses but first I had to get past the Horseshoe Crab (Limulus polyphemus) which, I guess, was the display creature of the day. For those who need to know such things, the horseshoe crab is ‘bled’ to obtain Limulus amebocyte lysate (LAL) which is an aqueous extract of amoebocytes. LAL reacts with bacterial endotoxin or lipopolysaccharide and it is this reaction which is the basis of a test called the LAL test. The LAL test is used in the pharmaceutical industry to detect the presence of, or quantity of, gram negative bacteria endotoxins. Prior to acceptance of this test, a rabbit test was used for this quality testing purpose. When I was an inspector of parenteral drug manufacturing sites back in the ’70s, this LAL test was still considered a new test method and was still undergoing validation procedures in parallel to testing in rabbits. I think that the ladies showing me their horseshoe crab were a bit surprised that I knew this much about their horseshoe crab:-). I was surprised at how little I had forgotten in 30 years! LOL

Tennessee Aquarium, Chattanooga, Tennessee (Part II)

Penguin swimming

The first part of this multi-part posting of my visit to the Tennessee Aquarium focused on the orchids and butterflies exhibits and a few of stingrays on exhibit. This Part II highlights the reefs and the jelly fish displays. The jelly fish are a bit tough to photograph because they are in constant motion but I was surprised by the number of different varieties that the Tennessee Aquarium had on display and the amount of aquarium space that they had allocated to displaying these interesting creatures. Part III covers the “River Journey” building.

Tennessee Aquarium – Chattanooga, Tennessee (Part 1)

The Tennessee Aquarium located in Chattanooga, Tennessee is housed in two buildings located beside each other on the riverbank of the Tennessee River. One of the buildings is for predominately saltwater exhibits (the “Ocean Journey”), and the other is for predominately freshwater exhibits (the “River Journey”). An admission ticket to one building includes admission to the other building with a short outdoors walk to go from one building to the other. I began my visit by going to the “Ocean Journey” first. Inside, an escalator takes you quickly to the top floor of the building where there are a number of aquatic exhibits as well as many orchids and a butterfly exhibit area.

My cold camera met the near jungle environment with its high humidity and I was out of photographic business until I got my lenses to unfog many minutes later. Spent the time looking around, speaking to volunteer staff and another photographer who was, likewise, waiting for his camera equipment to warm up. Although this blog series is about a public aquarium, this first in the series will focus on mostly the orchids and butterflies found in these upper display area.
