Sea cucumber: Habitat to Habit

Question 1 · multiple choice

A rescue team is planning a habitat release for a healthy Sea cucumber. Which setting fits best?

tropical sandy seabeds, lagoons, and coral reefs tropical and subtropical seas, seagrass beds, and nesting beaches mangroves, estuaries, and lowland streams open woodland and savanna with scattered tall trees

Question 2 · multiple choice

To avoid giving unsuitable food, which menu should a Sea cucumber receive in a specialist wildlife centre?

deer, peccaries, capybaras, reptiles, fish, and other prey organic particles swallowed with sand or gathered from water insects, spiders, worms, and other forest-floor invertebrates insects, snails, worms, small animals, pet food, and scraps

Question 3 · multiple choice

Which observation plan is best aligned with a Sea cucumber's usual active period?

usually active by day feeding and migration activity varies with season and river flow often feeds continuously, with timing varying by species hunts by day in warm conditions

Question 4 · multiple choice

Which movement clue would help identify a Sea cucumber without using colour or sound?

glides over ground, climbs, and swims swims upstream using bursts, leaps, and precise current reading flies forward, backward, sideways, and can hover crawls using tube feet and body-wall contractions

Question 5 · multiple choice

A young engineer studies a Sea cucumber for a nature-inspired design. Which feature should be copied?

a flexible body and feeding tentacles process large amounts of sediment wide mouth and filter pads separate tiny prey from huge volumes of water uses the sun, moon, and polarised sky light to travel in a straight line massive jaws and crushing premolars allow it to process bones

Question 6 · multiple choice

Which parent-and-young scenario belongs to a Sea cucumber?

the queen lays eggs and workers feed larvae different diets many release eggs and sperm into water where larvae drift a foal can stand and follow its mother soon after birth young are raised in a tree hollow, den, or building cavity

Question 7 · multiple choice

Which observation accurately describes communication or cooperation in a Sea cucumber?

mostly solitary and strongly territorial around rich flower patches males defend calling sites while parents provide unusual care often gathers where organic-rich sediment is available mostly solitary but may gather around food

Question 8 · multiple choice

Which environmental change is most directly linked to the normal activities of a Sea cucumber?

regulates many prey species as a top predator turns and mixes forest litter while hunting invertebrates consumes many invertebrates but can disrupt ecosystems where introduced recycles nutrients and oxygenates seabed sediment

Question 9 · multiple choice

How is a Sea cucumber most likely to respond when escape becomes difficult?

ejects sticky tubes or internal organs in some species and later regrows them uses a hard shell and powerful swimming to escape threats dives quickly and uses sharp dorsal spines if swallowed delivers powerful kicks when threatened by large predators

Question 10 · true false

True or False: A sea cucumber produces cleaner, more alkaline sand that can locally benefit reef chemistry.
