This photo is of one of my kids picking up ripe caja-manga from the ground at his grandma's ranch. In the end, none of the caja-manga was edible--it was already attacked by the little beasties of the ground.
Caja-manga is one of the many fruits I have met here in Brazil. It looks a lot like a mango, but I personally like the taste of the mango better. It goes by many names: taperebazeiro, macucu, cajá, cajazeira, cajá-mirim, cajamanga, cajá-manga, taperebá, tamacoaré, tamaquaré-serrado, cajazeiro tapiribá, acaiamiri, acaíba, cajá-pequeno, cajá-miúdo (source here).

It's quite a fruit.
