Hidden under Mexico is 'Hot Tub of Despair' which instantly kills what swims into it

The bizarre bottomless pool, a 100ft (30.5m) wide pond, is filled with a toxic mixture of hydrogen sulphide, ultra-salty water and methane and only a handful of creatures can survive in it. The researchers discovered the toxic pond in 2015 and discovered that the banks were filled with preserved corpses of creatures who had tried to swim in the warm waters. The pool is said to be present more than 1,000m (3,300ft) below the Gulf of Mexico.
