Common name: Purple heart urchin

General information

The Purple Sea Urchin, Spatangus purpureus, is a species of sea urchin in the family Spatangidae. It is characterized by its distinctive purple coloration and oval shape. This species is not as commonly kept in home aquariums as some other sea urchins, but it can be an interesting addition for experienced aquarists who appreciate its unique appearance and behavior.

Care

Purple Sea Urchins require a tank with plenty of live rock and a sandy substrate to mimic their natural environment. They are sensitive to water quality and require stable conditions with low nitrate levels. Care should be taken to ensure that they are not exposed to copper-based medications, which can be lethal to echinoderms.

Reproduction

In the wild, Spatangus purpureus reproduces by releasing gametes into the water column, where fertilization occurs externally. In the aquarium, breeding is less common, but with optimal conditions, it is possible to observe spawning behavior.

Habitat

The Purple Sea Urchin is found in the Eastern Atlantic, from the British Isles to the Mediterranean Sea, and along the coast of West Africa. It typically inhabits sandy and muddy bottoms, often burying itself partially for protection and to access food. In the aquarium, providing a similar environment will help ensure the well-being of these urchins.
