New Mammal Species Found in Borneo

lemonysam writes "The BBC is reporting that a new mammal species has been discovered in Borneo by a conservation group trying to document the local species, as part an effort to prevent the destruction of their habitat by logging and agriculture. The species, which has not been identified by local experts or the indigenous population, is roughly the size of a domestic cat and is believed to be carnivorous."

Re:New "species" of "mammal"?

The article mentions:

"It's more likely to be a viverrid - that's the family which includes the mongoose and civets - which is a very poorly known group," Dr Isaac said.

That being said, they only have two photographs of it so far, so it's hard to tell what it is...

> I have a question: Aren't class, order, genus, and family entirely arbitrary? Shouldn't we now classify living things entirely with genetics?

Not entirely arbitrary. What's somewhat arbitrary is how high in the tree of life the branches that get those labels are. Unfortunately it's a big messy tree that wasn't designed for the convenience of classification.

Looks a lot like a Fossa

It really looks like a Fossa - usually native to Madagascar. Wikipedia Fossa.

It's a member of the Viverridae family, which is fairly poorly known, due to their being a) nocturnal b) rare and c) furtive.

Talk about a can of worms you just opened

Well, no, they aren't arbitrary, except in the pedantic sense that arbitrary means by making a judgement - as in the word "arbitration", and not in its modern sense of "just one person's opinion". They are based around the understanding of taxonomy available at the time. (And, ultimately, from the religious concept of the chain of being - it's remarkable that current Christian fundamentalism is actually regressive compared to 17th and 18th century Protestantism, and proof that society goes backwards as well as forwards.)

The whole area of the filing of lifeforms - taxonomy - is in a state of flux, and the best way to get a grip on it is to read the popular writings of Jay Gould, who is so sadly no longer with us. Classification with genetics is at an early stage and we still do not know how to measure genetic difference reliably - which is why there is now disagreement over how closely human beings and chimpanzees are related. We can measure very small genetic divergences in the same species, but measuring the size and significance of genetic diferences between related species is very hard.

Disclaimer - I am not a taxonomist, just someone who is interested in the subject. Which is why I urge you to read Jay Gould. Even if you aren't really that interested in the subject, his writings should be familiar to any reasonably well informed slashdot reader.

Giant squids have been confirmed for some time now, what they managed recently is photographing a live one.

Baeleen whales do indeed eat plankton (and sometimes krill), as they are filter-feeders. Toothed whales eat larger fish (sometimes caught in a net of air bubbles a group of whales will produce), squid and other larger sea creatures. Dolphins (which are technically in the whale family) are even known to eat porpoises (also in the whale family). Interestingly, there is actually footage of Orcas (which are dolphins) throwing porpoises through the air with their tail repeatedly to each other, before killing and eating them.

Toothed whales cannot (as far as I know) eat plankton, so they are definitely carnivores. Krill is animal, as are zooplankton (as opposed to phytoplankton, which is plant, and bacterioplankton, which is bacterial). This means that Baeleen whales are eating both plant and animal, so are technically omnivores.

Dogs are also omnivores - well, maybe I should say that they THINK they're omnivores. T. Rex was probably omnivore - there is evidence it ate plant material - and if they ever extract any DNA from the T. Rex organic material they've found, you may yet get the chance to eat one. Or vice versa.
