The female calf, named Nessa, weighed 9kg (20lb) and has a distinctive coat featuring both spots and stripes.'Wonderfully charismatic'Director of animal and plants at Chester Zoo, Mike Jordan, said the Malayan tapir was "under enormous pressure" because its numbers had "crashed" over four decades to "frighteningly low levels, with hunting and habitat destruction being the main threats to its survival".The calf's patterning will slowly change over the first six months of life to mirror the unique black and white pattern of its parents, Margery and Betong."We're over the moon that Margery has delivered a healthy female calf - a birth that marks an important moment in our efforts to prevent the extinction of this wonderfully charismatic but sadly endangered species," Mr Jordan said.Ms Owen said Nessa was a "real bundle of energy" and was confidently looking to explore but Margery was "extremely attentive and always has a watchful eye on her"."
