In the interests of recycling old material from Tet Zoo ver 1, I present… yes, a whole series of articles devoted to one of the most unusual and remarkable of hoofed mammals. Come on, we all love babirusas. If you’ve been with Tet Zoo from the beginning, none of what’s to follow will be new [adjacent photo from here]. For the rest of you: buckle up and enjoy the ride…

You might be surprised to learn that babirusas have been known to westerners for a comparatively long time, having been named Sus babyrussa by Linnaeus in 1758 (the generic name Babyrousa was first coined by Perry in 1811). In fact babirusas were first mentioned in the European literature as early as 1658, and there have even been claims that the Romans knew of babirusas in the 1st century AD. Linnaeus wrongly identified Borneo as the babirusa homeland, and over the following years other authors misidentified Sumatra, Amboina and elsewhere as the place where babirusas came from.

Today we know that they are endemic to Sulawesi, the adjacent Togean (or Togian) Islands, the Sula Islands (just east of central Sulawesi) and Buru (south-east of the Sula Islands, and the most westerly of the Moluccas). What might also surprise you is that the babirusas found across these islands are not all alike, and in fact the sort of babirusas we are all familiar with – those with naked skin and upper canines that curve in a circle – are by no means representative of these animals as a whole. Historically, babirusas were probably present across the whole of Sulawesi, but by the 19th century they had disappeared from the south-western peninsula. As of 1990, they were still present on Buru and two of the Sula Islands (Mangole and Taliabu), but have become extinct on others (Macdonald 1993). Thanks to logging, habitat destruction and illegal hunting, babirusas are under pressure across their range [image below shows captive male babirusa at Marwell Zoo, England. This individual is in the strange habit of covering his tusks with mud].

Sula Island and Buru babirusas have often been regarded as introduced. While this is likely (we know that Sulawesi people kept babirusas and traded them far and wide because of their remarkable appearance and good eating), these populations actually represent distinct taxa, the biogeographical origins of which remain obscure. However, it’s also conceivable that the Sula and Buru babirusas colonised the respective islands naturally, as babirusas are very strong swimmers and well able to make short sea journeys. On Sulawesi, babirusas have been observed swimming across the 10-km-wide Lake Poso (Melisch 1994).

Well, this was a brief intro. Lots more to come!

    I’m waiting for the explanation of the highly provocative title. Babirusas aren’t suids? Or anthracotheres are, and have nothing to do with hippos? I hope it turns out to be the former, because that would be more fun.

    there have even been claims that the Romans knew of babirusas in the 1st century AD.

    Very interesting. Details, please!

    a Babirussa is mentioned at the beginning of ’20,000 Leagues Beneath the Sea’ it gets left behind at a hotel when Prof Arronnax leaves New York to hunt the mysterious monster (that turns out to be the Nautilus).

    Mud-covered tusks might alleviate cold temperature sensitivity, possibly mammoths and shovel tuskers in cold climates did that too? Yay babirusas!

    The anthracothere idea is bogus, but it’s been suggested a few times: in his 1981 book on pigs, Colin Groves even said ‘previously I have dismissed such an idea, but really it is impossible to place a finger on any definite resemblance of the Babirusa to any other suid, and perhaps it is an anthracothere after all’ (Groves 1981, p. 3). Clearly, it’s too interesting not to mention. It’s discussed in a later article (the next one, I think).

    The ‘Roman link’ is, unfortunately, something I know next to nothing about: in discussing Piso’s 1658 description of the babirusa, Groves (1980) stated ‘Even if, with Mohr (1958: 67-68), we reject the notion that it was known to the Romans in the 1st century A.D…. [this] is still remarkably early’ (p. 45). So, you’d need to see Mohr (1958) to go further with this, and I don’t have this reference. Let me know if you can track it down!

    A most interesting wild Pig, the name does sound Biblical

    is the Marwell specimen learned in sheathing blades? (just a thought)

    Harry Turtledove once wrote a short story in which a breed of pig was engineered to be kosher…in his intro (in the anthology), Turtledove mentioned that after he wrote the story, he discovered there really was a kosher-qualifying pig – the Babirussa.

    Greeting folks, I’m from Indonesia. I am curious as to the statement that the Romans knew about babirusa. Did babirusa use to live in other parts of the world? I used to think they can only be found in Indonesia (Sulawesi is one of the 5 major island of Indonesian archipelago).

    Given that Roman merchants regularly went to India, and that the Indians had contacts further east, and that the Romans liked to import exotic animals, it wouldn’t be all that strange if they encountered captive babirusas, or even brought a few to Roman territory.

    Anthony, how can the babirusa qualify as kosher? Does it ruminate?

    No, not at all… no resemblance to Hebrew that I can see.

    Did babirusa use to live in other parts of the world?

    No.

    > Anthony, how can the babirusa qualify as kosher? Does it ruminate?

    I guess its complex, multi-chambered stomach might have led to that suggestion.

    If you squint and distort some of the phonetics, you can sort of get it to fit as something vaguely Hebrew, or Aramaic.

    It would be an effort, but there are pareidoliac linguists who think like that.

    Wait a minute – does this mean that babirusas are descended from the Lost Ten Tribes of Israel?

    For all who think Babirusa has anything to do with the middleastern languages, it is derived from 2 Indonesian words, which would place the word origin there, and partly in Portugal.

    Thanks to Mr. Andreas Johansson and Mr. David Marjanovic for addressing my question.

    In response to Mr. Tim Morris, indeed, the word babirusa is derived from 2 Indonesian words :

    1) Babi : The Indonesian word for pig.

    2) Rusa : The Indonesian word for deer.

    I applaud the idea for its novelty and empathic approach!
    (I know my teeth don’t like too-cold air)..
    But.. why only cover the front two tusks?
    Investigation needed!
