The usage of 'interspecies' seems so obvious to most that hardly anyone checks the wiki. It's probably futile to try to keep it tagged contrary to the actual meaning of the word: two different species. Which applies to both of the above examples.

So, does this mean that the wiki for interspecies should remove the requirement that the relationship be actually interfamilial? ("They should always be from different sub-classes" = interfamilial)
Then it would be in a sense, 'okay' to tag such images like coyote+dog or lion+jaguar as interspecies, as obvious it may be.
