A little perspective
Cabbage head vs Sea hare: length comparison
The head diameter of a cabbage head is approximately equal to the body length of a sea hare.
A cabbage head is the compact, leafy, edible part of a green cabbage plant, commonly used as a vegetable.
A sea hare is a soft-bodied marine mollusc related to sea slugs, capable of releasing ink when threatened.
