Pseudoboletia indiana, commonly known as the pebble collector urchin, is a species of echinoderms belonging to the family Toxopneustidae.

[4] The pebble collector urchin can be found in Hawaii, New Zealand, Easter Island, and Madagascar.

[5] Pseudoboletia indiana lives on the ocean floor, at up to 100 m (330 ft) in depth.

[5] The urchin uses debris from the ocean, such as pebbles, broken pieces or coral, seaweed, to cover itself.

[4] During the night, the urchin will abandon the pebbles and coral it uses as camouflage and will roam around.
