swims steadily by sweeping the rear body and broad tail walks on land and climbs trees but adults cannot swim walks backward while rolling a dung ball with hind legs runs with great endurance rather than relying on one short sprint

Question 5 · multiple choice

A close observation reveals one feature especially suited to a Coconut crab. Which is it?

branched body hairs collect pollen while a honey stomach carries nectar striped coats may confuse biting flies and help individuals recognise one another powerful claws open hard foods while modified gills breathe moist air touch receptors in the front paws become especially responsive when wet

Question 6 · multiple choice

What is the best description of a young Coconut crab's start in life?

lays eggs that develop through miniature juvenile stages kits are raised in an underground earth and fed by adults a cria is usually born during daylight and stands quickly larvae develop in the sea before young crabs move onto land

Question 7 · multiple choice

Which social arrangement fits a Coconut crab rather than the distractors?

mostly solitary and competes around rich food sources mostly solitary outside breeding mostly solitary at sea but gathers during migration adults often patrol territories while some populations migrate in groups

Question 8 · multiple choice

Which cause-and-effect chain correctly starts with a Coconut crab's normal behaviour?

pollinates flowers while moving between nectar sources recycles fallen fruit and carrion on islands moves nutrients between leaf litter and small plant pools scavenges dead material and preys on small reef animals

Question 9 · multiple choice

A researcher keeps a safe distance because a Coconut crab may do what when cornered?

hides in crevices and survives long periods with little food uses coordinated pack defence, warning growls, and avoidance retreats to burrows and uses exceptionally strong claws kicks, bites, spits stomach contents, and uses size
