INDEX Analysis:
Exerpt from civilian eyewitness account - "It looked like-- like some flower out of a nightmare. Screamed like one, too. Then it just... disappeared."
The Lurker is capable of close-quarters combat. More likely behavior is to warn nearby Archæan and then conceal itself (QUERY: Active cloaking).
EXTRAPOLATIONS:
Assessing possible Weak Point: Evidence suggests the Lurker's head is particularly susceptible to damage. Supported by the prevalence of hardened plates of carapace. Probability - High.
Speculating on ability to cloak: The Lurker's surface may be covered in photoactive cells. Possibly explains ability to bend and emit visible light. Requires more data. (INSERT: Mira - Samples confirm your speculation. How the cells are able to do this is still a mystery. @INDEX)
ENGAGEMENT PROTOCOLS:
The Lurker's weakest point is its head which can only be damaged once its carapace unfolds.
ADDENDUM: The Lurker is capable of triggering photoactive cells in nearby Archans making them temporarily undetectable in the visible spectrum.
