Birds who feed marine food remove salt by means of which gland?

A. Rectal salt gland 
B. Digestive glands
C. Pituitary glands
D. None of these

🧠 Explanation:

Birds that feed on marine food remove salt via the rectal salt gland, a specialized organ. For biology students, this highlights avian physiology, making it a key topic for studying animal adaptation, marine biology, and environmental science. The gland ensures salt balance. Understanding this reveals how birds survive marine environments. It’s essential for analyzing animal physiology, ecological adaptations, and biodiversity. Studying the rectal salt gland offers insights into how organisms adapt to harsh environments, crucial for biology, ecology, and conservation, ensuring knowledge of avian survival mechanisms in marine ecosystems.
