Sacculina carcini is a common species of barnacle that not only attaches itself to various species of crab, forcefully castrating males and turning them into females willing to care for and release their eggs.

Most barnacles spend their entire existence attaching themselves to underwater rocks or the bottoms of ships and just filtering food from water, but sacculina carcini has evolved into a parasite that seeks out unsuspecting crabs, usually green crabs, and becomes the bane of their existence. It all starts with a microscopic Sacculina larva that attaches itself to the most vulnerable part of the crab, the membrane at the base of one of its hairs, and injects a microscopic blob called ‘vermigon’ into the crustacean’s bloodstream. This blob then grows into a parasitic barnacle that uses its host both for protection and reproduction, often changing its sex to achieve its insidious goal.

A popular seafood restaurant in Singapore has been criticized online for its “cruel” claw machine which gave patrons the chance to catch a live crab for $5 a token.

The chief executive of House of Seafood has had to issue a public apology after a viral video showing people using a pink claw machine to catch live crabs drew a lot of criticism both from the general public and Society for the Prevention of Cruelty to Animals (SPCA). In a statement posted on Facebook, Francis Ng claimed that the live claw machine was actually meant to educate children about marine life, while critics of the controversial attraction said that it caused unnecessary harm to the crustaceans and encouraged people to see the live creatures as thing to be won in a game. As a result of the backlash the claw machine attracted, House of Seafood decided to temporarily close the machines at all of its locations.

What’s the last thing you’d expect to find in a vending machine? Ok, so it may not be hairy crabs, but you have to admit this is pretty weird.

I’ve posted some weird vending machines here on Oddity Central, like the gold dispenser in the UAE, or the contaminated water vending machine, but this latest find really takes the cake. Located in the Xinjiekou subway station, in Nanjing, China, this particular vending machine is full of live hairy crabs and crab vinegar, making it available to enjoy seafood on the go.

The quirky food dispenser was installed on the 1st of October, and at first, it surprised even the Chinese. People would stop and stare at the crustaceans inside, and others would even take out their cameras and take photos of them. Business was out to a slow start, with only one hairy crab sold per day, but as people got used to the thought of buying live crabs from a vending machine, the figures jumped to an impressive 200 crabs a day. People noticed they were cheaper than the crabs found at the local food markets, and buying them on their daily commute they also saved precious time.

Depending on size, crabs can be bought for 10 RMB, 12 RMB, 25 RMB and 50 RMB. They all seem dead, but their actually just hibernating due to the low temperature in the vending machine.
