In a medium bowl, combine lime juice, shrimp, and sprinkle with salt. Stir gently to coat the shrimp evenly. Let marinate for 15 minutes at room temperature.

Once marinated, add mango, avocado, red onion, jalapeño, and cilantro. Fold everything together gently to avoid mashing the avocado.

Taste the mixture and adjust the salt or add more lime juice if desired.

Transfer to a serving dish or individual bowls and garnish with extra cilantro leaves and lime wedges. Serve immediately.
