Tacos de camarones are filled with what seafood?

Tacos de camarones are filled with shrimp.

The Spanish word camarones means “shrimp,” so tacos de camarones are shrimp tacos. Wikipedia describes them as a Baja California specialty made with grilled or fried shrimp, usually placed in a corn or flour tortilla with accompaniments such as lettuce or cabbage, pico de gallo, avocado, and a sour-cream or citrus-mayonnaise sauce.

The seafood filling is what defines the name, not one particular cooking method. Shrimp may be grilled, fried, sautéed, or battered, depending on the cook and region. That makes these tacos different from fish tacos, even though both often use similar toppings and sauces.

A common mix-up is treating camarones as a generic word for seafood. It specifically refers to shrimp; octopus is pulpo, lobster is langosta, and cod is bacalao. Baja-style shrimp tacos are closely associated with the coastal cuisine of northwestern Mexico and have also become popular in California and elsewhere.
