3  Class Scyphozoa  Bell is up to 2 feet  Bell is translucent to milky with a bright yellow center (gonad mass)  Bell margin has 16 large lobes  Each lobe has up to 25 tentacles  Tentacles can reach 20 ft. in length  Typically drifts motionless or with gentle pulsing

4  Found in temperate oceans (typically cooler water)  Feeds on smaller jellyfish and other gelatinous zooplankton  Prey becomes ensnared in the tentacles (acts like a drift net)  Sting is very weak  Many small crustaceans (larval crabs and amphipods) ride on its bell and even steal food from its oral arms and tentacles

5  Fried egg jelly found in the Mediterranean sea

9  World's only sea-going lizard  Found only on the Galapagos Islands  Found mainly on rocky shores  Usually 2-4 ft in length  Average weight is 3 lbs.

10  Thought that land and marine iguanas diverged from a common ancestor at least 10 million years ago  Equipped with a nasal gland to excrete excess salt

11  Before feeding they must raise their body temperature to ~ 96.8°F (can lose up to 50°F when in the ocean)  Feed primarily on marine algae  Dive during high tide (usually 3-16 ft.)  Dives are usually only a few minutes but have been recorded up to a half hour

12  Mating territories are defended by males  Males assemble large groups of females to mate with, and guard them against other males  Females dig burrows in the sand where they lay 1-6 eggs  Leave the eggs to incubate for about 89 to 120 days

13  Marine iguana enjoys a habitat with few predators  Known predators are hawks, owls, snakes, crabs, rats, and feral dogs and cats  Females and eggs are most susceptible  Displays a highly aggressive behavior to bluff its way to escape  This species is completely protected by national legislation (Ecuador)  Listed as Vulnerable
