Its a bit wordy, I think it would be much better if it was broken down into sections with subheaders such as:
Natural History:
size, range, behaviors etc
Housing:
AZA housing standards, filtration, custom building enclosures, lighting, etc.
Feeding:
foods eaten in wild, foods available in captivity and supplements
Health Issues:
common health issues and possible causes
Costs
average cost to house and feed for a year, etc.
Legality
In this way you can snap right to the section you were looking for and it will be much easier to read. When I read the version you posted I automatically started skipping over sections because they were so verbose. It wasn't very visually appealing and a sticky needs to be sweet and to the point. Try to be less journalistic and stick to the hard facts and things that aren't a matter of opinion or hearsay. Not saying you didn't but just elaborating.
