Russian marine biologist Alexander Semenov deserves full respect from us. His team dives a few oceans to study about jellyfish population. Almost 80% of these species is still mysterious, undiscovered or unexplained. At a few hundred feet beneath the sea water, you will see nothing- everything seems so dark. But if you try to look harder, you will see colorful creatures flying around you. Wish his team with a blessing success in studying the creatures.
