Jellyfish come in a wide variety of shapes and sizes. The largest is the lion's mane jellyfish (Cyanea capillata), which can have a bell over six and a half feet in diameter and weigh up to 440 pounds; the smallest is the Irukandji jellyfish, several species of dangerous jellyfishes found in tropical waters, which measure only about two. This sedentary behavior makes the upside-down jellyfish an easy animal to track behaviorally.
Abrams and Ravi Nath, a Caltech graduate student and a co-author of the jellyfish study, joined forces with Bedbrook to investigate just what the jellies were doing.

Biology and Anatomy of Jellyfish The biology and anatomy of jellyfish are crucial to understanding their unique characteristics. These organisms, though simple in structure, exhibit complex behaviors that are essential for their survival. Jellyfish are ancient and diverse marine invertebrates that have inhabited the oceans for over 500 million years.
Despite their seemingly simple structure, these gelatinous creatures exhibit a variety of behavioral adaptations that allow them to survive in their diverse aquatic environments. These behaviors range from how they find food to how they avoid becoming prey. Acquiring Food Jellyfish.
Jellyfish and the Environment: A Delicate Ecosystem The impact of jellyfish on the environment is a complex and often overlooked topic. Jellyfish blooms, for example - sudden increases in jellyfish populations - can have significant consequences. They can disrupt fishing industries, damage coastal ecosystems, and even affect tourism.
