Question

Sepia releases ink, which helps in

• A. Capturing the prey
• B. Impairing the sensory functions of its predator
• C. Locating food
• D. All of the above

Answer 1

Answer: (B)

Impairing the sensory functions of its predator

Many species of cephalopod of phylum Mollusca releases a dark pigment into water, called as cephalopod ink. This ink is released from the ink sacs, which are located between the gills. Its dark colour is caused by melanin, which is its main constituent. The cephalopods release ink into the water, so as to impair the predator's view. The ink released in the water creates a dark, diffuse cloud-like a smoke screen which can obscure the predator's view thereby allowing cephalopod to make a rapid retreat by jetting away. So, the correct answer is option B.
