Do you know the name of this tropical fruit?

This  fruit which has only local names....but no 'common denominator' English name. Its funny looking fruit with thin dark brown, sandy skin which can be peeled off to reveal 'smooth, marble-like' crisp orange flesh. Once skinned, it resembles a persimmon. Once cut open, there is a heart-shaped seed which is removed - one bite reveals a crunch which tastes like a weird fusion of carrots and fresh peas! Help!
