Tanya Streeter was born and raised in Grand Cayman is a world champion free-diver, who made her first important breakthrough in 1998 when she bettered Deborah Andollo's Women's No Limits diving record by 10 feet, achieving a total depth of 370 feet (113 m). She has been known to hold her breath in static apnea for up to 6 minutes.

In 2002, she broke the men's no limit world diving record by diving to a depth of 525 feet (160 m) near the Turks and Caicos Islands, a record which was surpassed later that year by the late French freediver Loïc Leferme. In 2003 she also broke the men's variable ballast world record by diving to a depth of 400 feet (122 m).

Recently Tanya has featured in various BBC and Animal Planet documentaries as well as appearing on a set of five commemorative postage stamps distributed by the Turks and Caicos Islands in 2003; making both her and the Virgin Mary the only women outside of a royal family to be featured on such an item.

Tanya currently lives in Austin, Texas USA with her husband Paul.
