It's good to see you making big fauna...relatively speaking. I was going to ask how it can survive in the boreal habitat when it seems to not have notable adaptations for mountain winters, but Sagan 4 seems warm now, with reduced ice caps, so the adaptive need is probably lower.
I like it distinctive coloration.
I noticed the angle of the lower eye of the eye triangle is slightly farther back than more typical arrangements, which could be useful.
There are two cases of "it's" in the first two sentences when "its" is meant.
"important sicne" Since.
"cluches" Clutches. "However to get to it" That's a rather choppy sentence. I recommend merging it with a previous sentence.
" its arsenal," The comma should be a colon.
"Argusraptor Complex eggs and larva" That should be "larvae".
