That is according to a wildlife conservation charity Born Free.
A survey conducted in 2020 revealed that 3,951 dangerous wild animals are licensed to be kept privately in the UK.
They warn that many more could be held without a licence.
Employees at the charity created an interactive map which showed the number of dangerous animals in each council area.
This covers 210 private addresses across 129 local authorities, and animals include lions, tigers, crocodilians and venomous reptiles.
Creatures being kept in local authority areas around Portsmouth including Havant Borough Council, Portsmouth City Council, Winchester City Council, Chichester District Council, Hart District Council, East Hampshire District Council, Isle of Wight Council, and New Forest District Council.
Here are the animals listed, according to the charity.

The cobra female last week gave birth to 13 leucistic monocled cobras. It was the zoo's first birth of these snakes, that can usually be found in northern Thailand. Their species is normally white and they retain the colour of their eyes, which is different from albinism. The baby cobras will be presented to the public from February 10. / AFP PHOTO / MEHDI FEDOUACH (Photo credit should read MEHDI FEDOUACH/AFP via Getty Images)
