Q. Which type of ecosystem is associated with the recent discovery of fascinating animals like transparent sea cucumbers and pink sea pigs?
Answer: Abyssal Plains
Notes: During a recent deep-sea expedition to the Abyssal Plains in the Pacific Ocean, transparent sea cucumbers, pink sea pigs, and bowl-shaped sponges were discovered. Abyssal plains are flat ocean floor regions, usually at the base of continental rises, found mostly in the Atlantic Ocean. They cover 40% of Earth's ocean floor, occur at depths over 6,500 feet, and are composed of basalt covered by various sediments. The Sohm plain is the largest.
