A chimpanzee wearing a top hat, a lion and a zebra are some of the stuffed animals worth £100,000 that have been stolen from a south London warehouse.
The theft took place at a taxidermy warehouse in Wandsworth on the evening of 1 March, at about 7:20pm, the Metropolitan Police said.
It is believed the thieves arrived in a Luton van with a grey cab and white body, using axle grinders to break in.
They then made off with 18 stuffed animals.
Detective Constable Edward Bird said: "This was not a random crime, the burglars had came prepared and well equipped. This was a criminal enterprise and these thieves need to be stopped before they commit further crimes.
"The items they stole are of high value and are very distinctive. I am appealing for anyone with information to contact police, in particular I would ask anyone who deals in such animals to be on the look-out and contact police immediately if you are offered any of the stolen items."
