In a small bowl combine the shrimp with 1 cup of fresh lime juice, making sure the shrimp is completely submerged. Let chill in the fridge. The shrimp will take 10-12 minutes to cook in the lime juice, they will turn pink once fully cooked.
While the shrimp cook in the lime juice, make the mango habanero sauce. In a blender, combine the remaining 1/2 cup of lime juice, half of the diced mango, the pineapple juice, garlic, habanero, coriander and salt. Blend until smooth then taste for salt.
On a large serving dish, lay down your cucumber on the outside perimeter of your dish. Arrange your shrimp butterfly side down with half of the head end on the cucumber and the tail end on the dish. Nestle the red onion in the center, then lay the avocado on top followed by the rest of the diced mango. Drizzle as much of the mango habanero sauce over the shrimp as you’d like, then finish with a sprinkle of sea salt. Serve with tostadas or saltine crackers.
