A novel species with 20 arms and a distinctive body shape has been identified in the depths of the Antarctic Ocean. Scientists aboard a research vessel made the discovery while trawling the frigid waters. The new species, named “Antarctic strawberry feather star” (Promachocrinus fragarious), was detailed in a study published in the journal Invertebrate Systematics. These “otherworldly” creatures, resembling strawberries, can change color and inhabit depths of 215 to 3,840 feet in the Southern Ocean. With DNA analysis and distinct body features, researchers confirmed the existence of this new addition to the cryptic sea animals known as feather stars.
Prelims pointer
- Promachocrinus fragarious: This is the scientific name given to the newly discovered species, referred to as the “Antarctic strawberry feather star,” due to its unique appearance resembling a strawberry.
- Cryptic Sea Animals: These are elusive marine organisms that are often difficult to locate due to their behavior, habitat, or physical characteristics that enable them to blend into their surroundings.
- Southern Ocean: The Southern Ocean surrounds Antarctica and is the body of water that encircles the continent. It is characterized by its cold temperatures and unique ecosystem.
- DNA Analysis: This is a scientific technique used to examine an organism’s DNA to determine its genetic makeup and relationships with other species.
- Invertebrate Systematics: The journal where the study about the new species was published. It focuses on the classification, evolutionary relationships, and diversity of invertebrate animals.
