The Secret Life of the Zoo
8pm, Channel 4
It is billed as a candid look at nature red in tooth and “aww!” at Chester Zoo, but this behind-the-bars documentary series often resembles a furrier version of First Dates. Love – or at least some sort of pungent musk – always seems to be in the air and tonight’s season-five opener is no exception, with a breeding pair of meerkats sniffing out their new digs, some Sumatran orangutan siblings preparing to give birth and a rescued two-horned chameleon meeting a couple of horny suitors.

The Assassination of Gianni Versace
9pm, BBC Two
If it is the underlying psychology that interests you, then this penultimate episode of the crime drama offers the most answers yet. It is a portrait of killer Andrew Cunanan’s dysfunctional childhood, shown in parallel with Versace’s formative years at the knee of his dressmaker mother in Calabria. Ellen E Jones
Benidorm
9pm, ITV
Joyce is positively fuming after the appalling performance by Sammy (a returning Shane Richie) at Neptunes, made all the worse once she discovers that Monty has given him a contract at Solana. Elsewhere, Doreen makes a dreadful blunder by sending off Pauline’s novel to be published prematurely. Ben Arnold
One Born Every Minute
9pm, Channel 4
Forty-year-old Sarah and 29-year-old Tom await the birth of their second child. Sarah hopes to establish a strong bond with her daughter from the moment she arrives in the world. Meanwhile, Dawn and Scott are expecting baby number eight, so they should know the drill when they arrive on the ward. Candice Carty-Williams
First Dates
10pm, Channel 4
The dating show continues its 10th run, now with Come Dine with Me levels of predictability, but it is uplifting nonetheless. Among tonight’s pairings are charity worker Freddie and fashion buyer Rebecca, plus singers Gina and Nik. In a surprising twist, engineer Steve meets medic Lyn, who is pregnant. Hannah J Davies
Station 19
10pm, Sky Living
A new drama about a Seattle fire crew that is exactly as you would expect once you learn it is a Grey’s Anatomy spin-off. The odd blaze is put out, but there is a lot more romantic strife, wrapped thickly in voiceover homilies, too-cute dialogue and intrusive indie pop. Jaina Lee Ortiz is strong in the lead role. Jack Seale

The Spy Who Came in from the Cold (Martin Ritt, 1965), 11am, Film4
Richard Burton’s agent Alec Leamas is world-weary cynicism personified in this gritty John le Carré adaptation. Sent to East Germany to match wits with his communist counterpart, Mundt, he has a sad affair with Claire Bloom’s Nan Perry, a pawn in the intelligence chess game. Paul Howlett
