 The species occupies different habitats throughout their lifetime and although they may feed on a wide variety of prey items, the proportions of the different prey could vary among different life stages and corresponding size classes.This could be a result of what is and isn't accessible to a small stingray versus a relatively large stingray that is able to dig deeper into sediment and extract particular types of prey like the bat ray ("Myliobatis californica") is able to do."D.
