What is a submersible?
A submersible is a small boat or other craft, designed especially for research and exploration. Compared to a submarine, a submersible is more limited in its movement and how long it can stay underwater. While a submarine has enough power to leave port and come back to port under its own power, a submersible needs a mother ship that can launch and recover it.
The submersibles are white tubes of about 6.7 meters long and 2.8 meters wide, and have a top speed of three knots or 5.5 kilometers (3.5 miles) an hour, reported AFP.
