The helmet shell feeds on sea urchins by dropping its entire shell on the prey. It also secretes sulphuric acid which I have personally seen when live shells were brought ashore.

1. Is the sulphuric acid used to dissolve the hard shells of prey they feed upon?

2. Defense?

3. Any other specific function?

Looking forward to your inputs
