We all know there is a certain hierarchy of sympathy (up to outright "Speciesism", to paraphrase this overused slogan of animal rights activists) within the different species displayed at zoos. Also among zoo people, who are mostly interested in large mammals (and to a lesser degree, birds). Even on this forum of zoo nerds, you'll find way, way more threads or photos involving elephants, tigers and giant pandas than coral cobras, sturgeons or sea pens.
That's just the way most humans are. However, this does not mean that the husbandry demands of the latter should be ignored or that they should be considered less worthy - on the contrary! You can do your part by learning more about them and distributing this knowledge to others to improve their situation.
As a keeper and exhibitor of such "neglected creatures", this gives me the great opportunity to teach people more about hitherto unknown creatures. Inspiring people for gorillas is easy. Inspiring people for coral cobras? Challenge accepted!
