A good exemple should be the “harpoon” in cone snails (Conidae), which is created from a modified tooth inside their proboscis. (Cone snail with proboscis, from KQED.org) The harpoon is launched at prey at close distance, and is used to poison and stun prey, and later to pull them in. According to high-speed camera capture the harpoon is launched in just ...

An excellent example (unless you consider this a tool) of a weapon using animal would be the "web casting spiders" which are a diverse group of spiders known as the Deinopidae. These spiders create a special elastic web that they hold between their fore-feet, and then dangling down from a surface, they expand and push the web onto their prey. There ...

Definitely appears to be Pentatomidae (as others have pointed out) due to shield-like, broad bodies. With over 4500 species and larval stages demonstrating significant variability even within species, ID can be difficult without knowing specific fauna, size, habitat, etc. The OP doesn't list a size, but because OP is viewing under a scope, I assumed this is ...

To answer your other question about the eye: Yes, shield bugs (Pentatomidae), like most insects, have compound eyes. Buschbeck and Friedrich (2008)1 discuss this highly conserved trait found in most arthropods. Also, the red dot medial and nearby the eye? That's an ocellus, a simple eye. Oregon Department of Agriculture 1: Buschbeck, E.K. and Friedrich,...
