Pink Tank Scuba was diving near Blairgowrie Pier in Port Phillip Bay, Victoria, Australia, when they saw something odd.
From a distance, it looked like rubble or possibly coral…but no, it was over 1,000 spider crab crawling over each other to make a huge pyramid on the ocean floor.
Nope, definitely not coral.
It’s a giant heap of NOPE.
This is fascinating, but it may convince you to stay on dry land.
At this time of year, spider crabs usually collect for a mass migration and molt.
However, ensure such a spider crab pyramid seems to be pretty unusual( even for regular divers in the area ). According to Hirschfield( via Grind TV ), “The behaviour I observed was truly merely a lot of climbing and a few scuffles as crab got in each other’s faces…A few of the crab in the pyramid were also adorning themselves with sponges becoming decorator crab, which is a camouflage mechanism.”
Not merely that, but these pyramids don’t last very long.
So, these divers were just a luck few who were able to witness such a large, skin-crawling event.
