How comb jellies adapted to life in the deep sea

Washed up on a beach, a comb jelly or ctenophore (pronounced "teen-oh-four") might look like a little transparent grape. But ctenophores are extremely diverse, living from the equator to the poles and from the ocean surface to more than 7,000 meters, or more than four miles, down. MBARI researchers and their collaborators are developing computer models that compare the genetic material of many species of ctenophores to learn how their body chemistry has evolved to life in different environments.
