You are moving in slow motion, and now your back is exposed to the spider. It leaps on top of you.
Your own screams fill your helmet as you call for help. But the metal mask muffles your cries.
The spider bears down on you with gaping jaws. You feel a searing pain in your back as the spider rips your diving suit open like a piece of paper.
Water rushes into your suit, and you feel a sudden, crushing weight. You can no longer move. You can no longer scream. The end comes quickly.
