Question

Venomous sea-snakes possess a

• A. Compressed tail
• B. Printed tail
• C. Depressed tail
• D. Conical tail

Answer 1

The correct option is A Compressed tail

Sea snakes occur mainly in the warm tropical waters of the Indian ocean and western Pacific ocean (the Atlantic, Caribbean and Red sea have no sea snakes), with a few species found well out into Oceania. Sea snakes have laterally compressed tails used to propel them through the water, nostrils with valve-like flaps which can be closed upon submersion, and lack any ventral plates.

So, the correct answer is option A.
