 * Among cartilaginous fishes (Chondrichthyes), the consumption of hard prey (durophagy) is most common in the clade of skates and rays. . . which contain only durophagous taxa . . . Durophagy in batoid fishes takes a variety of forms: diets can involve comparatively thin-shelled crustaceans, thick-shelled molluscs and/or prey with softer, tougher exoskeletons (e.g. shrimp or even insects) . . . Hard prey processing has not been extensively surveyed in batoid fishes, but at least two strategies exist . . .: what we will call "chemical durophagy," where predators rely on low stomach pH or chitinase to break down prey exoskeletons . . . and "mechanical durophagy", where predators crush prey before ingestion . ..
