Material from 'Haikouicthys'

[edit]

Below is text from the differently spelled 'Haikouicthys' article, now redirected here. Maybe someone thinks something from this should be integrated into the article. (If 'Haikouicthys' is a valid alternative name and not just a misspelling, it should be mentioned in the article.) -R. S. Shaw 20:53, 27 April 2006 (UTC)[reply]

Hakouicthys was an early craniate. Lived in the Cambrian period. It was the first creature known to have a notochord, a primitive spinal column.

  • Life

Haikouicthys had one main predator, Anomalocaris. Haikouicthys was a scavenger, often being hunted itself. Haikouicthys was able to swim especially fast for the period, because of its flexible spine. Most creatures with a rigid structure for anchoring muscles had exoskeletons, which limited their ability to flex their body for swimming. Haikouicthys could flex its entire body as part of its swimming motion, a technique brought to a very high level of efficiency in modern fish like tuna.

  • Interesting facts
    • There are fossils of haikouicthys preserved so well that its internal organs can be seen.
[edit]

I think that there's a mistake in the taxobox. An animal can't be like a simple fish that then evolves into a different class, and in millions of years, they shortly go back to the class that they were in. GBA

I slipped on my keyboard. I removed it because "it's speculation, we get it." Giant Blue Anteater 01:58, 19 June 2007 (UTC)[reply]

Pigmentation

[edit]

Is the choice of pigmentation in the drawing arbitrary? Is there any means by which a fossil can predict that? I was thinking that because this fish isn't really that much larger than Paedocypris (unless it is known to be fatter from side to side), it might have been almost as transparent.
