Moon jelly: Animal Science Quest

Question 1 · multiple choice

A habitat sign describes the home of a Moon jelly. Which description belongs on it?

tropical evergreen and moist deciduous forest cool freshwater canals and lakes around Mexico City coastal seas, bays, harbours, and estuaries woodland edges, scrub, gardens, and building surfaces

Question 2 · multiple choice

What food choice best fits the teeth, bill, or feeding tools of a Moon jelly?

aquatic insect larvae, worms, and small crustaceans wood-boring larvae, insects, seeds, nuts, and sap mainly other snakes, including some venomous species zooplankton, eggs, larvae, and tiny drifting animals

Question 3 · multiple choice

Which daily routine is most typical for a Moon jelly?

drifts and pulses continuously without a day schedule travels and feeds across day and night during vast migrations most active on exposed mud during suitable tides workers forage by day when weather permits

Question 4 · multiple choice

Which action sequence best matches a moving Moon jelly?

swims continuously with long front flippers contracts its bell to move slowly through water uses muscular pectoral fins to skip and crawl over mud flies between flowers and walks and dances inside the hive

Question 5 · multiple choice

A close observation reveals one feature especially suited to a Moon jelly. Which is it?

a specialised mucus coating prevents the host anemone from stinging it book gills exchange gases and can function briefly while kept moist on land mucus and fine cilia carry trapped food toward the mouth forms a dried tun state when water disappears and metabolism nearly stops

Question 6 · multiple choice

What is the best description of a young Moon jelly's start in life?

releases eggs and sperm into water where larvae develop eggs overwinter inside a protected silk sac mothers give birth in snow dens and emerge months later with cubs alternates between a tiny attached polyp and a free-swimming medusa

Question 7 · multiple choice

Which social arrangement fits a Moon jelly rather than the distractors?

often forms blooms when currents and food concentrate individuals breeds and feeds in large, noisy colonies mostly solitary, gathering around large carcasses usually solitary but forms temporary feeding aggregations

Question 8 · multiple choice

Which cause-and-effect chain correctly starts with a Moon jelly's normal behaviour?

stirs stream sediment and controls aquatic invertebrate populations consumes plankton and feeds turtles, fish, and other predators creates cavities later used by other birds, bats, and insects helps regulate populations of other snakes

Question 9 · multiple choice

A researcher keeps a safe distance because a Moon jelly may do what when cornered?

retreats to canopy and uses a powerful bill if cornered hides, swims away, and can regrow damaged limbs transparent body and mild stinging cells offer limited protection jumps away, hides, displays bright mouthparts, or bites if trapped

Question 10 · true false
