She just wants a hug! Ever watched one getting ready to wait? Often, as they draw the arms back, there is a 'click', a small jerk, just as the arms reach the widest. This engages a catch that they can then pull their muscles against, and release it when a prey item comes close; sort of like snapping your fingers. This makes the arms close very rapidly, hugging even the biggest or fastest prey. Add very potent venom and a drag line to catch them if they fall off, and medium-sized crabs can catch and feast on much larger bumblebees, for example. The contrast of #1 is excellent, and #2 is an excellent, classic shot!
