Drift into the remarkable biology of jellyfish—from their water-rich bodies and lightning-fast stinging cells to changing life stagesspecialized sensesocean food webs and glowing deep-sea survival strategies.
Answer choices reshuffle whenever the page loads. The 150-second timer begins after your first answer.
Animal ClassificationChallenge level: ★☆☆
1
Jellyfish belong to which animal phylum?
Correct answer: Cnidaria. Jellyfish are cnidariansa group of mostly aquatic invertebrates that also includes corals and sea anemones. A defining feature of the group is the presence of specialized stinging cells called cnidocytes.Body-plan insight: Many jellyfish have radial symmetryso major body structures are arranged around a central axis rather than along a left-right body plan.
Jellyfish AnatomyChallenge level: ★☆☆
2
What is the thickjelly-like middle layer of a jellyfish called?
Correct answer: Mesoglea. Mesoglea is the elasticgelatinous material between the outer epidermis and inner gastrodermis. It makes up much of the jellyfish’s volume and provides support without the heavy bones or shell found in many other animals.Water-rich design: A jellyfish is about 95 percent waterwhich is why its body loses its familiar shape when removed from the sea.
Stinging BiologyChallenge level: ★☆☆
3
What is the specialized stinging cell of a jellyfish called?
Correct answer: Cnidocyte. A cnidocyte is the specialized cell that contains a capsule called a nematocyst. When triggeredthe nematocyst rapidly fires a threadlike structure that can help inject venomentangle prey or defend the jellyfish.Precision matters: “Cnidocyte” names the complete stinging cellwhile “nematocyst” usually refers to the firing capsule housed inside it.
Nervous SystemChallenge level: ★★☆
4
Without a centralized brainwhat helps many jellyfish detect and respond to stimuli?
Correct answer: A diffuse nerve net. Jellyfish generally lack a centralized brainbut a loose network of nerve cells coordinates basic movement and responses. This system can process information from sensory structures that detect such cues as lightorientationtouch and chemicals in the water.Important exception: A simple nervous system does not mean no sensory ability. Box jellyfishfor examplepossess clusters of eyesincluding some with lenses and retinas.
Life-Cycle FormsChallenge level: ★★☆
5
Which two body forms appear in the life cycle of many jellyfish?
Correct answer: Polyp and medusa. The polyp is usually a smallattached formwhile the medusa is the familiar free-swimmingbell-shaped form. In many speciespolyps reproduce asexually and medusae produce eggs and sperm for sexual reproduction.Life-cycle lesson: The drifting jellyfish seen in open water may represent only one stage of an animal whose earlier life was attached to a surface.
Juvenile DevelopmentChallenge level: ★★☆
6
What is the juvenile jellyfish released from a strobilating polyp called?
Correct answer: Ephyra. During strobilation in many true jellyfishthe polyp forms stackedplate-like segments. Once a segment separatesit is called an ephyra; it then grows and develops into the adult medusa form.Vocabulary link: “Strobila” describes the stacked structure“strobilation” is the process and “ephyra” is the newly released juvenile.
Moon Jelly EcologyChallenge level: ★★☆
7
What forms the main diet of the moon jelly Aurelia labiata?
Correct answer: Zooplankton. Moon jellies feed on tiny drifting animals and other zooplankton. Their short tentacles sweep food toward a mucus layer around the bellafter which cilia and oral structures help move captured material toward the mouth.Food-web insight: Jellyfish are predatorsbut they are also prey for animals such as sea turtlesocean sunfishfishes and even other jellyfish.
Look-Alike AnimalsChallenge level: ★★☆
8
Comb jellies belong to which phylumseparate from true jellyfish?
Correct answer: Ctenophora. Comb jellies are gelatinous animalsbut they are not true jellyfish. True jellyfish are cnidarianswhereas comb jellies are ctenophores and usually swim with eight rows of fused cilia called comb plates.Visual illusion: The rainbow shimmer along a comb jelly’s rows is generally caused by light scattering from moving cilianot by bioluminescence.
Box Jellyfish SafetyChallenge level: ★★★
9
Which statement about box jellyfish venom is most accurate?
Correct answer: Only a few of roughly 50 species have venom that can be lethal to humans. Box jellyfish vary greatly in danger. A small numberincluding the Australian box jellyfish Chironex fleckerican cause life-threatening envenomationbut it is inaccurate to treat every box-jelly species as equally deadly.Behavior insight: Box jellyfish are unusually active swimmers and possess clusters of eyesfeatures associated with more directed movement than the passive drifting often associated with jellies.
Deep-Sea DefenseChallenge level: ★★★
10
How may the deep-sea crown jelly Atolla use its blue bioluminescent display?
Correct answer: To startle an attacker and attract a larger predator toward it. When disturbedAtolla can produce spinning patterns of brilliant blue light. The display may disorient the immediate attacker and work like a “burglar alarm,” drawing the attention of a larger predator that could attack the original threat.Deep-sea adaptation:Atolla also has a red bell that appears dark in deep waterhelping it remain less visible where red wavelengths from sunlight do not penetrate.
