TMAF about A coral grouper that loses prey into a crevice will swim tens of meters across the reef to find a specific moray eel it has hunted with successfully before, then shake its head at the hole until the eel follows it back. The behavior meets the same criteria used to test great ape gestures.

TMAF about - The 2003 Antwerp diamond vault heist is the cleanest case study in how defense-in-depth fails. 10 independent layers, each beaten by something trivial — hairspray on the IR sensor, aluminum tape on the magnetic contact — because the attacker had 2.5 years of tenant access to study.
