Imperial Sputnik Urchin: A Specialist’s Fascinating Invertebrate

A captivating echinoderm with distinctive blunt spines, the Imperial Sputnik Urchin is a highly specialized marine invertebrate best suited for advanced research or public aquarium environments.

Overview

This unique sea urchin, *Phyllacanthus imperialis*, boasts a robust, often brown or black test adorned with thick, blunt spines that display striking hues, including red, gray, or purple. Primarily nocturnal, the Sputnik Urchin emerges at night from its hidden crevices and burrows within coral rock to forage. During daylight hours, it prefers to remain concealed, contributing to its elusive nature in its natural marine habitat. Its unique appearance and behavior make it a truly fascinating creature to observe.

Care Level

The Imperial Sputnik Urchin is considered an *extremely* challenging species for aquarium keeping, with very few documented successes in private setups. It is not generally recommended for the home aquarium trade. This invertebrate is exclusively for expert aquarists or public institutions prepared for its highly specialized needs. Its nocturnal habits and diet demand careful consideration for tank mates and comprehensive care.

Tank Essentials

A very spacious and highly mature marine aquarium of at least 400 litres is the recommended minimum for this urchin. Maintaining exceptionally stable water parameters is crucial. Keep temperatures consistently between 24.8–25.7°C. While specific pH requirements for this species are [data unavailable], typical marine conditions (pH 8.1-8.4) are generally necessary. Excellent water quality and consistency are paramount.

Diet

The Sputnik Urchin is a nocturnal scavenger, primarily feeding on encrusting invertebrates and sponges found on live rock and coral surfaces. Providing a consistent, appropriate natural diet in captivity is a significant challenge. It may also graze on algae. Supplemental feeding with high-quality marine-based foods might be accepted, but adapting to prepared diets is not guaranteed.
