Here's what I want to write on the Kaluga Sturgeon, to add a little backing to the article. I'm new to Wikipedia, so if anyone has some advice I'd love to hear it:

Physical Characteristics
The Kaluga Sturgeon has a total of 10-16 dorsal scutes, 32-46 lateral scutes, 8-12 ventral scutes, 43-57 dorsal fin rays and 26-35 anal fin rays. (Want to definently add some more backing here, weight, color, etc...)

Diet
Kaluga are predatory, feeding on small invertabrates in their first year, and juvenile pelagic fishes in their third and fourth year. At adulthood, they will eat almost anything smaller than them, from fully grown salmon, invertabrae, and smaller sturgeon.

Decline
The species has seen a sharp decrease since the late 1800s, estimated at 80%. This is primarily due to the legal and illegal trade for it's roe, which is used as caviar. Another new cause is pollution in the Amur River Basin, which has caused difficulty in reproduction. The IUCN had it listed as Endangered in 1996, and Critically Endangered in 2010. It's wild population is currently in decline.
