Universality of indeterminate growth in lizards rejected....

[kinyonga]

" The only examined chameleons with completely absent GPCs were two old Chamaeleo calyptratus (Fig. 2b), one Furcifer oustaleti, and one Calumma parsonii"...
"GPC persistence in fully grown individuals of agamids and chameleons can be caused by reduced longevity limiting the time window available for the GPC degradation process"...
"we found preserved GPC in most of the studied chameleons, which points to their potential ability to grow throughout the life"...

In English?

 

[kinyonga]

So now you want it translated from English to simple English?

Does this help a bit?
"growth plate cartilage (Gpc) in the epiphysis of long bones, which is responsible for longitudinal skeletal growth by the endochondral ossiffication process."

Epiphysis...the end part of a long bone.

 

[kinyonga]

Endochondral ossification".cartikage is replaced by the bone...this growth occurs at the epiphysis.. and a couple of other places.

Lobster and bass have indeterminate growth. The older they are, the bigger they are.

Dogs and cats have determinate growth. Once they are "mature" they do not get bigger.

This study is to find out if the old wise tail is true, and "lizards never stop growing".

Im still waiting for the study "the lizard will stop growing if you keep it in a smaller tank, just like a fish"

This is a neat study topic. I am looking forward to reading.

[kinyonga]

It definitely makes e think!

 

[Motherlode Chameleon]

This study was an good read.

Some fish. I never got guppies to grow any larger than... a guppy!
OTOH, I've seen what goldfish & koi are like.

Chameleons—much less other reptiles—never struck me as having indeterminate growth.

Ossification, I'm familiar with; it's fused & stabilized several of my vertebrae.

Never a problem Jeremy!

I always figured that because they shed they must be growing....but then I didn't know if there were other reasons for shedding....like wear and tear on the skin.

 

[Klyde O'Scope]

Bingo. We 'shed' too, but it's more like 'flake'.
Interestingly, fish—which have scales—do not shed.

Apparently, fish scales are different than reptile scales, which are different than bathroom scales.

A bit off topic but when did @kinyonga go from Chameleon Enthusiast to Chameleon Queen?

In this thread was where someone first pointed out the covert maneuver from normal person to chameleon queen: https://www.chameleonforums.com/threads/jackson’s-outside-for-the-night.182697/page-2#post-1667491

It was a surprise to me. Not something I expected to happen!

I see what you did there

I believe it was 1953.

 

[Klyde O'Scope]

Oops... Sorry—wrong queen.
