Which anatomical features enable the viperfish to consume prey larger than itself?
Answer
An expandable stomach and a large gape
The viperfish is equipped with a large gape and a highly expandable stomach, both of which are critical for survival in the deep sea where food sources are unpredictable. These adaptations allow the fish to ingest meals that exceed its own body size, which is a vital mechanism for maximizing caloric intake during the infrequent opportunities when prey is encountered. Without these features, the energy-intensive process of hunting in a nutrient-poor environment would be far less sustainable.
