Review the paragraph at the top of page 2. What is the connection between the caloric
content in a cup of jellyfish and biologists
researching why marine animals eat
jellyfish?

All jellyfish are Cnidaria, an animal phylum that contains jellies, sea anemones, and corals, among others. There are more than 10,000 species of Cnidaria, and less than 4,000 of these are Medusazoa—those animals we think of as jellyfish. Those 4,000 jellyfish can be divided into four different groups.

Explanation:

"There was as yet no man, nor any animal, nor bird, nor fish, nor crawfish, nor any pit, nor ravine, nor green herb, nor any tree; nothing was but the firmament."
"Lo, now how the heavens exist, how exists also the Heart of Heaven; such is the name of God; it is thus that he is called."
"And the creation was verily after this wise: Earth, they said, and on the instant, it was formed; like a cloud or a fog was its beginning."
