World's Tiniest Vertebrate Found 37

foidulus writes "The BBC reports that American scientists have identified the world's tiniest fish living around Australia's Great Barrier Reef. It is also the tiniest animal with a backbone. The male of the stout infantfish is only about 7 mm(or less than 1/4 of an inch) long. It has a life span of only around 2 months which scientists say may be an advantage because it can evolve rapidly."

    ...to put in your ear.

    Have they tested the translation capabilities of these little critters?

    25.4mm/4 = 6.35mm
    I would say just over a 1/4 of an inch

    We need to destroy these creatures before they evolve into something that can take over the human race! With only a 2 month lifespan, they could easily out-evolve us within our children's lifetimes!

    Sentience is theorized to exist in the thalamus, which is a feature that evolved with vertabrates. You are in the cerebral spinal fluid in the third ventricle between the lobes of the thalamus.
  • Am I the only one who thinks they're showing a picture of the wrong fish?

    The areticle clearly states that the stout infantfish is ~7mm long. The picture shows a fish that is clearly 10mm long. Which makes me think that the picture they're actually showing is a picture of the world's second smallest fish, the goby fish.

    Stupid beeb editor.

    *may* be an advantage? That's awfully certain. Not to mention that by this logic bacteria have a greater advantage over pretty much all other life, since they can "evolve" so rapidly. So, living longer lives is no longer an 'advantage'? The article itself says:

    "It's interesting that these animals experience several generations a year," said Dr Watson. "This suggests they could evolve qu

      The way I've seen evolutionary biologists write about this, is that built in length of life is optimized differently for different situations/evol. niches.

      For instance, it's quite expensive in energy to build bodies that can age (good cell repair, etc) so if the average time before an animal is eaten by a predator is sh

        I posted to early and missed the last part:

        the biologists probably don't know enough about the living situation for the fish to have more than hypotheses about why their generations are optimized like that.

        So the researchers probably don't know yet.

        (And yes, bacteria do evolve fast. That's why our immune system isn't based on DNA -- we have too long generations.)

  • In tons of biology and genetics classes, people selectively breed fruit flies because of their short lifespan (among other reasons.) These guys could be useful in a similar reguard, but now we'll all have vertebrates to play with. I can't wait.
    • True, but (I say this as a question as I am not 100% on this) but are there not rules regarding the use of vertebrates in science?

      I remember in good old elementary school where we couldn't use vertebrates in experiments. (at least when it came to looking inside them or "treating" them to your new chemicals.)

    Sea-Monkeys® are a true miracle of nature. They exist in suspended animation inside their tiny eggs for many years. The instant-life crystals, in which the eggs are enclosed, preserve their viability and help to extend still further their un-hatched life span! Sea-Monkeys are real Time-Travelers asleep in biological time capsules for their strange journey into the future!

    We're equipped for this world here and now...

Sure, I could adjust, but how well? This body was created specifically for life in the 21st century
  • As I sit here doing my morning Slashdot readings, I came up with a thought that has me a bit perplexed.

    It says these fix evolve quickly. Let us say there is a minor evolutionary change every five generations or so. That would be one year to have five changes. By the fifth change, there may be a marked difference between the new fish and the its great great grandmother/father.

    My question is this. How long until the evolution creates a new species? Two years down the road, will you be comparing two sepa
