This is real and it's cooler than the tweet makes it sound.
The condition is called gynandromorphy. Researchers in India found three specimens of Vela carli, a freshwater crab from Kerala's Silent Valley, with both male and female reproductive organs.
First time it's ever been documented in this entire crab family. They ruled out pollution since the park is protected, so they think it's basically birth defects.

@spaceandtech_ Bro can self pollinate ??
@grok is there any word that i can call ??

Like India's gynandromorph crab, butterflies develop as bilateral genetic mosaics one half male, one female from early embryonic cell errors.
These natural chimeras serve as living labs, revealing cell-by-cell sex determination independent of hormones and advancing developmental genetics insights.
Bilateral gynandromorph Papilio memnon (Great Mormon) butterfly specimen from the museum collection, clearly split down the midline with the left side showing male wing coloration, body structure, and antennae while the right side displays female traits high-information visual of the phenomenon in another species.

💡 This could really confuse folks suffering from gender identity... or maybe the crab's just living its best non-binary life while we all overthink ours. Science wins again. Nature's been non-binary longer than Twitter debates.🚨Scientists in India just found a Vela carli crab in Silent Valley that's literally half male, half female (gynandromorphy—first time in this family!). Nature's out here serving binary confusion on a shell.

@spaceandtech_ With how polluted their waters are, it really shouldn't be surprising to find mutants.

@spaceandtech_ It’s now lgbtqia++c . The C is got crab

@spaceandtech_ Is it me or does India tends to be a hub for genetic mutations ?

In March 2026, researchers in India documented a rare biological phenomenon in a freshwater crab species called Vela carli which exhibited traits of being both male and female.
This condition, known as gynandromorphy, was discovered in three specimens found in the tree holes of Silent Valley National Park in Kerala's Western Ghats. Unlike hermaphroditism, where an organism possesses both sets of functional reproductive organs, these crabs are "biological mosaics," displaying male physical structures on some parts of their bodies and female features, such as gonopores (genital pores), on others.

@spaceandtech_ In evolution everything goes to CRAB
We started the ocean, we're gonna end in the ocean

@spaceandtech_ It would be interesting to know if it can self-reproduce

@spaceandtech_ Trump be like "That's the America Crab, it's red, white, and blue, I invented that"

@spaceandtech_ For those who don’t know, these particular animals have Gynandromorphism, a rare mutation where animals have male and female 2nd sexual characteristics due to the of XX and XY chromosomes (i think) ☝️🤓 and Most gynandromorphic individuals are sterile

@spaceandtech_ A Spider 🕷 Species Called Damarchus Inazuma Found In Thailand 🇹🇭
It Has Bilateral Gynandromorphism
( Physically Split Into Half-female & Half-male Characteristics )
Found In Kanchanaburi
This Rare "Wishbone" Spider 🕷Is The First Documented Case
