Edit: I am wrong.

I don't think it is. ChatGPT tends to have impeccable grammar and sentence structure. While this comment is very well-written, it has a few grammatical errors and some awkward wording, which are decent tells that it was written by a person.

Some examples:

1. "snake-handler"

'Snake handler' should not be hyphenated, but it is several times in this comment.

2) "...essential parts of 'serpent synchrony' - a fascinating area in herpetology..."

Several times the author uses a hyphen when they should be using an em dash: —. You can see this in the example above, and several more times throughout the comment. People often use hyphens in place of both en dashes and em dashes, because it is annoying to type the alt codes for those characters. ChatGPT, however, will always choose the correct type of dash, in my experience.

Also, in the above quotation, the single quotation marks should be double quotation marks (a similar mistake is also made in the fifth paragraph). Single quotation marks are for quotations within quotations, or for indicating that one is speaking about a word itself. Double quotation marks are the appropriate choice when indicating unusual terminology.

3) "However, things get particularly interesting when..."

The fourth paragraph starts with the word 'however', but this is not the appropriate conjunctive adverb for this context, because this sentence is not in any kind of conflict with the preceding sentence or paragraph.

4) "As he extends his arm, it's a subtle play of dominance and illusion."

This sentence structure doesn't really make sense. The use of the word 'as' to indicate concurrence clashes with the non-temporal statement following the comma. It should either be:

"The extension of his arm is a subtle play of dominance and illusion."

or

"As he extends his arm, he demonstrates a subtle play of dominance and illusion."

5) "His arm orientation..."

Here, the word 'arm' should be possessive:

"His arm's orientation..."

6) "...but it also taps into the snake's eclipse sensitivity - changes in pressure experienced during lunar eclipses, which oddly have a calming effect on cobras."

This one is subtle. Everything following the hyphen (which is meant to be an em dash) is intended as an explanation of the term "eclipse sensitivity" that precedes it. However, the way this is worded technically equates the sensitivity to the pressure changes themselves. It would be more correct to write something like:

"...but it also taps into the snake's eclipse sensitivity—a phenomenon whereby changes in pressure experienced during lunar eclipses have an oddly calming effect on cobras."

In all of my (fairly extensive) interactions with ChatGPT, I have never known it to make any errors like the ones described above.

This comment has been my best attempt to imitate ChatGPT.
