The marbled crayfish or marmokreb, a mutant species that didn’t exist 25 years ago, is considered one of the most invasive freshwater creatures in the world, and it’s all due to its remarkable capacity to clone itself.

The rise of the the marbled crayfish as an internationally recognized invasive species can be traced back to the mid 1990s, when German aquarium hobbyist whom experts prefer not to identify, for privacy reasons, bought a large crayfish described to him as a “Texas crayfish”. The man was immediately stunned by its size and the enormous batches of eggs it could lay. He started bragging about it to his friends, and giving away specimens. Marmokreb-mania was in its infant stages, but as marbled crayfish started appearing in pet shops, aquarium hobbyists started noticing something peculiar…

Miracle Milly, a six-year-old Chihuahua from Puerto Rico, was awarded the title of World’s Most Cloned Dog, by the Guinness Book of Records, after scientists in South Korea created a whopping 49 genetically-identical copies of her.

The controversial Sooam Biotech Research Foundation in Seoul, South Korea, has been creating pet clones since 2006, and last year they approached Vanesa Semler, Milly’s owner about the possibility of creating clones of the adorable pooch to try and solve the genetic mystery that made her special. You see, Mily is no ordinary Chihuahua. She’s held the Guinness record for World’s Smallest Living Dog since 2012, and scientists have been wanting to know exactly what made her so tiny. So in August 2017, Sooam researchers started making clones of Miracle Milly, the number of which has currently reached 49.

I’ve heard of people buying extra pairs of their favorite jeans, but a Louisiana veterinarian has actually gone and gotten himself two extra copies of his favorite dog! Phillip Dupont spent over $100,000 cloning his beloved pet dog Melvin because he simply couldn’t bear to part with him.

Phillip had Melvin cloned about two years ago, and he now has two identical dogs – Ken Gordon, named after his uncle, and Henry Fontenot, named after his friend – with the same traits and characteristics as Melvin. The pups were around for the last year of Melvin’s life, who was nearly 12 when Dupont had to put him down last year, due to his failing health.

Ken and Henry have now replaced Melvin as fixtures at Dupont’s clinic in Lafayette. “They’re maturing into the dog that Melvin was,” said Paula, Phillip’s wife. “I used to tell people that Melvin was the office greeter – my office manager. Ken’s kind of taken his place. Henry has stepped up and is also greeting people. Now they have two dogs meeting people – standing up and putting their paws on my desk.”
