Question

Marine teleost is

• A. Ammonotelic
• B. Ureotelic
• C. Uricotelic
• D. None of the above

Answer 1

The correct option is A Ammonotelic

Marine teleosts are ammonotelic, as 56% of nitrogen excreted is in the form of ammonia. Generally, marine and freshwater fishes have a large percentage of ammonia and since they live in the aquatic medium, they have plenty of water to flush the ammonia.
Bony fishes are ureotelic, while cartilaginous fishes are ammonotelic. Thus, the correct answer is option A.
