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)

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.

Related to sharks?[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

Removed "This type of behavior is speculative."[edit]

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