Seven, nine, eleven, fourteen. The number varies with each individual. Despite its common name, the eleven-armed sea star can have anywhere from seven to fourteen arms. The arms are long and tapering. They are covered in short spines. The colour ranges from mottled brown to olive-green to purple. This provides camouflage against the rocky reef. Variation is the norm. Symmetry is flexible. The appearance is unpredictable. Under rocks and in crevices, it hides during the day. The eleven-armed sea star is a predator. But it is also prey. Large fish, octopus, and other sea stars will eat it. So it hides. It wedges itself into gaps where nothing can reach it. At night, it emerges to hunt. Stillness is safety. Motion is risk. The cycle is tidal. The response is instinctive. Survival depends on concealment. The hunt is slow but relentless. The sea star crawls across the reef on hundreds of tube feet. Each one is tipped with a suction cup. When it finds a mussel or a barnacle, it climbs on top. It attaches its feet to the two halves of the shell. It pulls. Slowly. Steadily. Until the shell opens a crack. Then it everts its stomach through its mouth. It pushes the stomach into the shell. The stomach secretes digestive enzymes. It liquefies the prey. The sea star absorbs the liquid. It withdraws its stomach. An empty shell remains. Digestion is external. Consumption is internal. The process is efficient. Regeneration is its superpower. If an arm is lost to a predator, the sea star grows it back. The process takes months. But the new arm is identical to the old one. If the sea star is cut in half, each half can regenerate the missing parts. This ability to reproduce asexually by splitting allows it to colonise new areas quickly. Loss is temporary. Regrowth is certain. Multiplication is possible. The strategy is robust. Rocky reefs and harbours provide its preferred habitat. The eleven-armed sea star lives from the low tide mark down to fifty metres depth. It occurs on reefs, in kelp forests, and among the pilings of wharves. It is common throughout New Zealand. From Northland to Stewart Island. It is one of the most frequently encountered sea stars in rocky intertidal zones. Distribution is broad. Adaptation is general. Tolerance is high. The Māori name Pātangatanga refers to its sprawling, spreading form. The arms reach out in all directions. Like the roots of a tree. Or the fingers of a hand. It is a fitting name for a creature that seems to occupy space in every direction at once. Language captures form. Name reflects structure. The description is precise. The observation is accurate. Climate change may affect it indirectly. Ocean acidification makes it harder for mussels and barnacles to build their shells. If the prey declines, the predator may decline with it. For now, the eleven-armed sea star remains common. A sprawl of arms on the reef. A patient predator in the dark. Resilience is tested. Limits are unknown. The future is uncertain. The present is stable. No one told it otherwise. It carries on. The rock stays cold. The water stays dark. The arm extends. The cycle repeats. It is a quiet victory. No fanfare accompanies it. No celebration marks it. The sea star simply exists. It continues its work. It maintains its watch. And that seems to be enough.
