I have a long body, but I do not have legs. I am known for my electric abilities.

From ancient eras have I stayed, ever roaming my murky glade. Neath murk and mire, I aim to scare. On rounded snout, my nostrils flare. Beware my wide and vicious smile. You will not see me after a while.

Of seven my size is unmatched Stretching from Asia’s coast to Cali’s shore With me many people have swam and splashed The deepest trench is one I bore

While my size is not standard, I’m used as a scale. I grow in the sun, though my flesh is quite pale Don’t open my hint, I’ll freely unlock it Are you happy to see me, or am I in your pocket?

When the weather's bad, I'm usually low. I can make you crack or help you grow, Cook your stew or slurp your drink, Or make you too nervous to think.
