A monstrous-looking sea creature that experts are unable to identify has been washed up on a tourist beach in Mexico.
The strange four-metre (13ft) long beast was found by beachgoers on Bonfil Beach, in the city of Acapulco, in the south-west Mexican state of Guerrero.

Stunned spectators gathered around and took photos, which they shared on social media, speculating about the possible species of the creature.
The floating body was brought to the shore by strong currents that have been affecting that particular part of the Mexican coast.
Although the coordinator of the Civil Guard and Fire Brigade, Rosa Camacho, believes the animal had not been dead for a long time, it still seemed to have rapidly started to decay.
She said: "We have no idea what type of animal this is, but I do know that it does not smell bad or have a fetid aroma.
"It is four metres long and was found on Bonfil Beach."
The many photos of the strange creature have been seen and shared online thousands of times and have provoked a debate about what kind of animal it is.
