It is interesting to note what American zoos have spent millions of dollars on over the past decade or so. Elephants and polar bears have already been discussed on this thread and certainly those are marquee species that require substantial, expensive housing and have been the two front-runners in terms of splashy new zoo habitats. Looking through the long list that I compiled it is intriguing to note the common occurrences of animals that require underwater viewing and costly pools (penguins, pinnipeds) but also the fact that jaguars, lions and tigers have been prominent within larger continental zones. Here is a breakdown of the most popular additions:
Elephant exhibits - 16 exhibits that have cost a minimum of $10 million since 2004
Polar bears - 12 exhibits
Lions - 11 exhibits
Sea lions/seals - 10 exhibits
Jaguars - 9 exhibits
Penguins - 9 exhibits
Tigers - 6 exhibits
Gorillas - 5 exhibits
