Help identifying this fruit and this gourd / squash, please?
Not sure about the gourd, but the "fruit" looks like a green coconut, though your specimen looks pale yellow.
When coconuts grow on the tree, they have a pale green, hard, covering.
When picked, the green covering is pulled off and most of the thick husk along with it (which is used to make coir ropes and matting), resulting in the hairy brown round thing seen in grocery stores.
The tree the "fruit" is on looks like a coconut palm.
