This small sea apple was originally described by Cherbonnier, 1988, and named as monotypic genus "Koehleria" and its species "unica".
Cherbonnier concluded that the genus Koehleria is most closely related to the also monotypic genus Pseudocolochirus Pearson, 1910. Since the differences were actually too small, Koehleria unica was renamed Pseudocolochirus unica.
Pseudocolochirus unica is a yellowish to beige-brown species, speckled with dark spots and irregular dark spots.
Particularly striking are the bright yellow body lines, which signal to potential predators that the sea apple is inedible.
Many representatives of the class Holothuroidea excrete their body poison during the dying process, the holothurin, which can quickly kill the entire remaining population of animals in an aquarium, so sea apples should remain where they come from, in the ocean.
Pseudocolochirus unica is not available in specialist shops.
