London Zoo is looking after some precious new arrivals tonight - two Mangabey Monkeys. Without the zoo's help the animals would become extinct. But as Sharon Thomas explains, a breeding programme and a little bit of patience - will help ensure their survival in the wild.
London Zoo has welcomed two new mangabey monkeys - which are among the most endangered primates in the world.
It's hoped the two females will boost the zoo's breeding programme, to sustain the population of this rare species.
Sharon Thomas reports.
"After a carefully-managed introduction process, the two girls are getting along famously with the rest of the group," say zookeepers, "With dominant male Lucky taking a particular liking to Mo - who quite enjoys the flirty attention."
London Zoo's efforts to increase the tiny population of one of the world's rarest primates have been boosted with the arrival of two female mangabey monkeys.
Kasi and Mo were both born in Dublin Zoo. They've been moved to London as part of a European breeding programme.
Zookeeper Tony Cholerton explains why Jae Jae the Sumatran tiger needed a swimming lesson.
Tiger keeper Teague Stubbington said: "Jae Jae loves chilling out in the Tiger Territory pool - especially on hot days - but we really wanted him to make better use of it and encourage his natural swimming abilities.
"Not only is swimming fantastic exercise for Jae Jae, the anticipation of getting to the meat stimulates his natural predatory instincts - and catching his 'prey' is the best reward he can get!"
A Sumatran tiger at London Zoo has been getting special swimming lessons - to help him keep cool.
Unlike domestic moggies, tigers love water, and Jae Jae the male Sumatran tiger is no exception.
The new Tiger Territory enclosure contains a custom-built pool and Jae Jae could often by seen relaxing in the shallow end.
But keepers wanted to help him make the most of the deep waters - and his incredible muscles - so decided a swimming lesson was in order.
To entice the big cat in, they devised a special raft that could be topped with yummy treats.
The floating raft is placed in the centre of the tiger's pool, which is over 1.5m at its deepest point, and topped with Jae Jae's favourite snacks.
The new raft forms part of Jae Jae's daily enrichment, helping to keep him active and stimulated.
Martin Stew has been enjoying the weather at London Zoo ahead of the first part of ITV's behind the scenes series on the famous attraction, which airs at 8pm tonight.
If you've been out today, you won't be surprised to hear that it's been the hottest day of the year so far.
It reached 26.3 degrees Celsius in St James's Park - that's nearly 80 in Farenheit.
Great weather for us, but what about the animals at London Zoo?
We sent Martin Stew to find out how they're coping with the heat.
