headless sea hare or not?

[blood_hound]

My sea hare got stuck on one of my power head and when I remove it and it started to bleed it last for 3 minutes so I put it on a bucket for a while. It did not move for about an hour and after that whe I was draining the water from the bucket it started to move again but I cannot see it head. I leave it for another hour in the bucket before I put it back on the main tank. But still I can't see it head

Is it headless or just hiding his head for a while because of the injury it sustain being suck by a powerhead.

Will it survive his injury? Is the blood bad for my tank b'coz It drips on my tank while removing the sea hare from the powerhead?
