Inside the World of the Peacock mantis shrimp

Question 1 · multiple choice

Which field camp would place a researcher closest to the natural home of a Peacock mantis shrimp?

open African savanna and grassland tropical coral rubble and reef burrows cold, dark groundwater caves of the Dinaric karst forests, tundra, grasslands, deserts, and mountains

Question 2 · multiple choice

Which food tray most closely copies what a Peacock mantis shrimp normally finds in nature?

ants and termites taken from many colonies nectar plus tiny insects and spiders snails, crabs, clams, and other hard-shelled prey ants, mites, and other tiny arthropods

Question 3 · multiple choice

Which activity schedule best describes a Peacock mantis shrimp?

often hunts by day and rests during hottest hours activity follows food patches and can continue day or night often works during cooler daylight or evening periods hunts mostly by day near its burrow

Question 4 · multiple choice

A Peacock mantis shrimp must travel through its habitat. Which movement strategy does it actually use?

walks, swims briefly, and strikes prey from close range walks, sprints briefly, swims, and follows scent trails swims steadily by sweeping the rear body and broad tail walks backward while rolling a dung ball with hind legs

Question 5 · multiple choice

A Peacock mantis shrimp succeeds in its habitat partly because of which adaptation?

keeps skin and mouth surfaces moist to exchange gases out of water club-like appendages accelerate rapidly and crack shells with impact and cavitation branched body hairs collect pollen while a honey stomach carries nectar striped coats may confuse biting flies and help individuals recognise one another

Question 6 · multiple choice

A wildlife nursery prepares for a young Peacock mantis shrimp. Which developmental fact should guide the team?

females bury clusters of eggs in beach sand lays eggs that develop through miniature juvenile stages eggs are carried and cleaned by a parent until hatching kits are raised in an underground earth and fed by adults

Question 7 · multiple choice

A group-behaviour study follows a Peacock mantis shrimp. Which result should the team expect?

usually seen alone or in pairs outside family periods mostly solitary outside breeding mostly solitary at sea but gathers during migration mostly solitary and strongly territorial around burrows

Question 8 · multiple choice

If Peacock mantis shrimp numbers fell sharply, which ecosystem service could be affected?

controls hard-shelled reef invertebrates limits social-insect colonies without usually destroying an entire nest pollinates flowers while moving between nectar sources moves nutrients between leaf litter and small plant pools

Question 9 · multiple choice

Which defence strategy is actually used by a Peacock mantis shrimp?

uses precise stomps rather than putting its face close to dangerous prey threatens with colour displays and can strike attackers hides in crevices and survives long periods with little food uses coordinated pack defence, warning growls, and avoidance
