The echidna is not a large animal, so it has small feet. Unlike its fellow monotreme, the platypus, it does not have feet with retractable webbing. On the other hand, it shares with the platypus the characteristic of feet with very sharp claws for digging.
No, tube feet are a characteristic feature of echinoderms, such as sea stars and sea urchins. Protists do not possess tube feet.
Echinodermates possess a water vascular system.
Echinoderms have tube feet, with the exception of urchins, which have spines. They are invertebrates. They also have no organs or eyes.
Closed hydrovascular for echinoderms, open haemolymphatic for arthropods. ^^
Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.
tube feet and
Echinoderms, such as seastars and sea urchins, use their tube feet to move. Tube feet have suction discs which allows the echinoderm to crawl or stick to various surfaces.
it's echinoderms,they are sea urchins,sea cucumbers,sea stars, and brittle stars. Echinoderms are a kind of invertebrate.

Yes echinoderms have that internal hydrological system that lets them run their tube feet.
