A lot of the time people on here don't know the names of smaller species such as warthog. Normally it's only larger species like gorillas and elephants that have their names made public. Some animals in zoos don't even have names.
At best their keepers may have nicknames for them. True, it is mostly animals the public loves to bits that get names. Pandas, gorillas, elephants, chimps, I could go on and on.
