Trying my idea again, hopefully you'll like it!
I can't say this is terribly interesting, but you might be on to something. More importantly, there are some typos and I feel like "how big are they?" is a distinct oversight. Like, Opabinia weren't very big; are these super-sized along with being alive when they should be extinct?
I'll go and fix some of the typos and give some minor edits.
I was trying to imply that the creatures were extremely large with the list of things they consume, which included whales. I guess I could be more direct in that regard
Immature instances have a weaker carapace
instances(…)are born fully mature.
^ These are contradictory.
the species's pack mentality
maximum size of six meters
These should be addressed in the first paragraph of the description. It's confusing for the reader otherwise.
Derogatory slang for merpeople used in Three Portlands.
Upon first reading, this read like merpeople are "used as something" in Three Portlands. I'd recommend changing it to:
Common derogatory slang used in Three Portlands to address merpeople.
it is discovered that SCP-3518 has evolved
"is" should be "was" and "has" should be "had"
over the span of █ weeks
Maybe this is just a nitpick, but I don't understand the blackbox here. Why censor the time here when every other 'amount of time given' isn't?
Also, something about the fourth footnote seems…off. Maybe it's poorly worded? I don't know how else to describe it. Sorry I can't give more helpful advice on that.
Novote due to the issues mentioned above, but definite upvote if they're addressed. I also wanna mention that the interview was really well-written.
I like this, though I feel it starts stronger than it ends. The "Incidents" seem improperly labeled to me, as they describe less incidents and more developments to this file, imo. It also could be fleshed out more the extermination efforts and struggles to bring them under control. Right now it kind of just fast tracks those into cliff notes that don't have the same impact to me.
Does Mr. Robertson ever decide to help? Knowing how quickly these things can reproduce, killing off 99.6% of these things isn't really enough to control their population for long. Insight and details on the artificially created aquatic fauna and 6 years of extermination attempts could be interesting. This is an extremely aggressive invasive species and would require great lengths to bring under control. What would the Foundation resort to to finish them off?
