The lobsters simultaneously clung to the sand to lay their eggs and died when the tide receded, creating an impressive setting.
Locals found the beach in Otago turning bright red and informed the national news agency RNZ, Guardian on May 29 reported. Determination lobster munida gregaria is the reason, according to Dr. John Zeldis, marine ecologist at the Center for Atmospheric Sciences and the National Water New Zealand. These crustaceans attach to sandbanks when the tides rise instinctively to reproduce, then die at low tide.

Over the past few decades, Zeldis has seen 20 to 30-centimeter lobster-covered shores in Otago from December to June. This phenomenon extends from the Catlins in the south to the Banks peninsula in the north.
This year, locals have reported a lot of discolored beaches. This shows that adult munida gregaria refuses to give up the ideal undersea spawning site and leaves millions of younger shrimp with no breeding grounds. They must look for opportunities on the sand.

" Behavior" settlers "t whine sand very important to the life cycle of shrimp munida gregaria. We parked in the deep sea 30-40 meters and then lived there for the next few years. This is where they lay eggs and create Therefore, the tendency to "settle down" is innate , " explained Zeldis.
While sometimes the beaches are flabbergasted, the death of shrimp makes up only a small fraction of the total number of individuals, Zeldis said. This species still grows well despite the constantly changing marine environment.
