Lucy and Maria Aylmer are twins - not that you'd think so from looking at them.
The 18-year-old non-identical twins look radically different; one is fair with straight ginger hair and blue eyes, the other is darker with a mane of curly brown ringlets and brown eyes.
The Gloucester-born pair raised eyebrows when they were born, and say no-one ever believes they are twins.
Lucy and Maria's mother Donna is half-Jamaican, while their father Vince is white.
"It was such a shock for [our mother] because things like skin colour don’t show up on scans before birth," Lucy told the Daily Mail.
"So she had no idea that we were so different. When the midwife handed us both to her she was just speechless."
"No one ever believes we are twins," Lucy continued. "Even when we dress alike, we still don’t look like sisters, let alone twins. Friends have even made us produce our birth certificates to prove it."
The pair have three older siblings, who they say are "somewhere in-between" them.
Lucy added: "Most twins look like two peas in a pod – but we couldn’t look more different if we tried."
Non-identical, also known as fraternal, twins occur when two separate eggs are fertilised by two separate sperm. Fraternal twins are the most common type of twins.
