bichir teeth

[Cohazard]

But if it's buried beneath flesh like you said in the other thread you created, how can you consider them teeth?

How can they be used for holding prey if buried beneath flesh?

Maybe next time you have a dead polypterus you can photograph the jaw without any modification to it or stripping any flesh.

I will read the paper more and see if I can find some elaboration on the splenial and it's function.

Err...

Just a hint: you probably shouldn't hand feed anything that can actually inflict damage to you.

Yeah thanks ! I really didn't learn my lesson

The teeth that are attached to the splenial bone can be seen even when the flesh are still present, especially the front area, those spiky looking teeth. The one that is being burried under the gums are the second row teeth, which I call the replacement teeth. They are NOT attached to the splenial. They are only attached to the maxilla and mandible. I actually call the teeth that are attached to the splenial, the third row.

I will try take pics of a dead lower jaw polypterus that still got its flesh on. Might take a while, maybe from the next shipment as oversea shipment will sometimes have dying bichirs.

That means more bichirs my friend or maybe a big tank for bigger monsters.

As for the lap's head, cleaning off the fleash is harder than I thought. Not as easy as the snakehead's head that I did last summer.

I've heard of using some forms of acid to clean flesh off of mammel bones. I'll do some research on that so that I'll be able to make a more useful contribution next time this comes up. Seems a popular subject around here.

i havent seen the teeth on my baby sengal bichir yet

hey guys, i'm getting to this late, but it's a very interesting thread (i don't stray far from the gar forum much these days).

anyway, in short, bichirs have ONE row of true teeth. as cohazard was alluding to, the "second, third,...rows of teeth" are not true teeth but tooth-like structures on those adjacent bones.

i'll dig up some more technical jargon in the near future, but we run into these sorts of teeth in many other fishes, but they don't "count" in terms of true rows of teeth.--

Backed up by a true expert with strong understanding of the biological science behind all of this.

Thank you.
