There is big excitement for the team in The Zoo on RTÉ One tonight, Thursday April 4, when one of Dublin Zoo's residents in the Californian sea lion habitat, Seanna, becomes a mum.

The baby news is a boost to the staff at Dublin Zoo following the death of patriarch sea lion Danny last year.

Staff discovered that Seanna had become pregnant by Danny before his death.

Seanna and Danny's pup is given the name Danny Junior - DJ for short.

Watch a very special clip here.

Also on tonight's episode, the Brazilian tapir calf starts exploring, keeper Garth introduces some of his favourite creatures in the Reptile House and there is serious concern about Alfie, the young male gorilla.

The Zoo is on RTÉ One tonight, Thursday April 4, at 7.00pm.
