A further hint - although the mulling over flags produced a false "lead" which I did not intend, that general line of thinking might be profitable.
Not yet, given there have only been four guesses so far I *will* say that there are two portions to the riddle, and each applies to a different part of the scientific name for the species in question. A feature belonging to Malta or Indonesia - species not known to be sanguivorous, against it's nature - genus
I think you can use that as a hint that we all don't have a clue... the first part about Malta or Indonesia could mean that the species name is an island nation, e.g. madagascariensis. The other explanation could be that it ends in *a*, but that would be the most silly hint in the history of this game... About the second part I don't have a clue what you mean there, but is somehow sounds right for Vampire crab...
after a while scanning down the Zootierliste inventory, how about Ducula bicolor? The generic name being related to Dracula (or Count Duckula), and the specific name relating to the two flags in question being bi-coloured.
And Chlidonias gets it Count Duckula was the latest in a long line of vampire ducks, who due to an accident during his resurrection ended up a vegetarian, and was a recurring character in the 1980's childrens cartoon Danger Mouse, and later the main character of his own eponymous cartoon. The Maltese and Indonesian flags are both classed as bicolor.... as noted previously, the fact the two colours in question were red and white was accidental. It is worth noting that a bicolor flag can contain more than two colours, through fimbriation or defacement, and equally that a flag containing only two colours isn't necessarily a bicolor. The Japanese flag, for instance, is not a bicolor flag.
it actually was Count Duckula in your answer! I can't see an Imperial Pigeon without thinking of Count Duckula, but I thought I was the only one.
This is another of those riddles which may be blindingly obvious (to Zoochatters of a certain age of television) or the total opposite (to young ones ). This animal belongs to Nasir.
Given your allusion to "a certain age of television" the first thing that comes to mind is Robin of Sherwood , which contained a Saracen character by the name of Nasir. Having ruled out a few lines of enquiry in my head, I took a look at the ZTL stocklist for the collection and recalled how you - like myself - do like a good (or terrible) pun....... Sarasins Minnow (Oryzias sarasinorum) is the answer, methinks My prior lines of enquiry, incidentally, were pondering on whether I could recall Nasir owning a pet during the series - as far as I know, he did not - and whether you would be so literal, and misleading, as to intend the answer to be one of the three species at Chester going by the name of "robin".
it is indeed Sarasin's Minnow. Every time I look at the Zootierliste stocklist and see that name it immediately makes me think of Nasir.
Little Rock is the capital of Arkansas and frog is part of a horse's hoof. Hence answer is little rock frog Staurois parvus
OK then. My original clue: This animal has a hole in its funny bone. Is the reason for the name of the genus to which the species belongs.
