The chocolate chip sea star, also known as the horned sea star, is a striking marine species native to the Indo-Pacific region. Named for the dark, cone-shaped nodules on its body that resemble chocolate chips, this sea star is a popular choice in marine aquariums for its unique appearance and relatively hardy nature. Found in shallow waters, this species plays a key role in the health of coral reef ecosystems.

  • Purple Tube Feet: The chocolate chip sea star has bright purple tube feet on the underside of its arms. These tube feet help the sea star move along the ocean floor and grasp onto surfaces, as well as assisting in feeding by prying open the shells of molluscs.
  • Defense Mechanism: The dark, raised nodules or “chocolate chips” on the sea star’s body serve as a defense mechanism, making it less palatable to predators. The hard, spiny texture of these nodules further deters attacks from potential threats.
  • Regeneration Ability: Like many sea stars, the chocolate chip sea star can regenerate lost arms. If an arm is severed, it can regrow over time, and in some cases, a new sea star may even grow from the lost arm segment.
  • Sensitive to Water Quality: Although relatively hardy, chocolate chip sea stars are sensitive to changes in water quality, especially fluctuations in salinity and pH. In captivity, they require stable, clean water conditions to thrive and maintain their vibrant coloration.
  • Omnivorous Scavengers: These sea stars are opportunistic feeders, using their tube feet to open the shells of molluscs and other prey. They play an important role in keeping the reef environment clean by feeding on detritus and dead organic matter.

Fabulous experience. We all loved it (2 adults and 2 kids 12+9). Really impressed with displays and loved the interactive part up close with the Skate. Definitely worth the visit and a beautiful town to visit.

I was 5 years old again! And I was able to caress rays that were just asking for that!
