TRANSCRIPT
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
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
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.
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
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
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
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
