What evolutionary characteristic allows snailfish to grow at a low metabolic cost?
Answer
Gelatinous tissue with low levels of protein, lipids, and carbohydrates
The consistency of their gelatinous tissue, characterized by a high water content and low levels of protein, lipids, and carbohydrates, is an evolutionary adaptation that permits growth at a low metabolic cost.
