The whale (tou khtou). Sea-monster, huge fish. In Jonah 2:1 the LXX has khtei megalwi. "Three days and three nights" may simply mean three days in popular speech. Jesus rose "on the third day" ( Matthew 16:21 ), not "on the fourth day." It is just a fuller form for "after three days" ( Mark 8:31 ; Mark 10:34 ).
