The Asian short-clawed otters, Keshika, Kasem and their pups from last year have been busy for the last few weeks rearing a set of twins.
Now the pups have reached 6 weeks old it was time to microchip and sex them. This gave us the chance to get a quick picture of what must be one of the most photogenic babies in the animal kingdom.
The pups should start to leave the nestbox regularly in a couple more weeks. Keep an eye out for them getting swimming lessons from the rest of the family.
