Underwater life is no magic. It is real in the tangible physical world. Where did such wonder come from? The same where every living and none living things (including planets and the origins of the materials and matters that form planets, stars, gases and forces) and creatures come from.
And God said, Let the waters bring forth abundantly and swarm with living creatures, and let birds fly over the earth in the open expanse of the heavens.
God created the great sea monsters and every living creature that moves, which the waters brought forth abundantly, according to their kinds, and every winged bird according to its kind. And God saw that it was good (suitable, admirable) and He approved it.
And God blessed them, saying, Be fruitful, multiply, and fill the waters in the seas, and let the fowl multiply in the earth. (Genesis 1:20-22)
Notes (excerpted from Wikipedia online)
The Monterey Bay Aquarium (MBA) is a non-profit public aquarium located in Monterey, California, United States. The aquarium was founded in 1984 and is located on the site of a former sardine cannery on Cannery Row. It has an annual attendance of around two million visitors. It holds thousands of plants and animals, representing more than 600 species on display. The aquarium benefits from a high circulation of fresh ocean water which is obtained through pipes which pump it in continuously from Monterey Bay. Sea life on exhibit includes stingrays, jellyfish, sea otters, sea horses, and numerous other native marine species, which can be viewed above and below the waterline. In January 1996, the aquarium opened the Outer Bay wing to provide exhibits covering the open-water ecology of Monterey’s Outer Bay. The MBA has more than 400 employees and over 1000 volunteers. Operating costs are largely covered by visitor admission, as well as by special events and membership dues. No government money is involved, with the exception of an occasional federal grant given to visiting scientists, for study.
