A local authority in Scotland will see 15 sets of twins attend primary school this week, with officials left wondering whether there's "something in the water".
When the new term begins in Inverclyde on Wednesday, more than 80 sets of twins will be enrolled for class across the region.
In 2015 the area saw a record 19 pairs enrolled for class.
Terry Loughran, convener of education at Inverclyde Council, said: "We seem to have an ever-increasing number of twins starting school, although it has scaled back slightly this year.
"It's a really exciting time for them, and for parents too, although it can occasionally provide a challenge for teachers identifying who's who as traditionally we would have the twins in the same class", he added.
New twins in the area are traditionally brought together for a photograph ahead of the new term, and this year was no different, as proud parents watched their children pose in school uniform in Clyde Square, Greenock.
Parent Sarah Goyal said: "It's so interesting to see all the different personalities here today.
"With my own twins, one is exuberant and one is quite quiet, and it seems to be the same with the others", she added.
