Heteropsammia cochlea, also known as walking dendro, is a species of small solitary coral in the family Dendrophylliidae that is native to the Indo-Pacific area.

The base in contact with the bottom is relatively circular, depending on the nature of the substrate it is either flat or slightly keeled.

The walking dendro is widespread throughout the tropical and subtropical waters of the Indo-West Pacific area from the eastern coasts of Africa, Red Sea included, to Philippines and from southern Japan to Australia and New Caledonia.

It may reproduce sexually by gamete release or asexually by budding of a new individual from the "parent body".

When breeding occurs in open water, the larva starts with a planktonic stage before landing and growing on the shell of a microgastropod that it will in time fully envelop.
