Barrow Island (Western Australia)
Encyclopedia
Barrow Island is a 202 km² (78 sq mi) island
located 50 kilometres (31 mi) northwest off the coast of Western Australia
. The island is the second largest in Western Australia after Dirk Hartog Island

The island contains no evidence of indigenous Australians
. Until last century, the island remained uninhabited, mostly because of a lack of water.
Whaler
s were known to operate in the area from about 1800 onwards. The first recorded visit by whalers was in 1842 with continued visits occurring until 1864. The island was used as a slave trading centre for Aborigines
during the 1870s by Captain William Cadell until he was arrested and removed from the colony in 1876. Slave labour was used in the nearby mainland pearling industry.
Guano

(Australia's biggest lizard
), Barrow Island euro
, Spectacled Hare-wallaby
, bettong
, golden bandicoot
, osprey
, and the Barrow Island mouse (Pseudomys
nanus ferculinus) are also present. Marine species include green turtle
and dugong
.
Limestone caves on Barrow Island support subterranean ecological communities. These include endemic and vulnerable species. Invertebrate species include Stygofauna
, amphipod crustaceans, of Nedsia, Liagoceradocus and other genera. These mostly inhabit an anchialine system, a 'lens' of fresh water above the saline ground water, which they share with species such as Milyeringa veritas—the Blind gudgeon. Troglofauna have also been discovered within the cave systems; these include the schizomid
Draculoides bramstokeri
and perhaps the only troglobitic
reptile—Ramphotyphlops
longissimus.
Hydrogen sulphide produced by the 'Barrow fault' may sustain this diverse community through chemoautotrophic energy production.
During Cyclone Olivia in 1996, Barrow Island experienced the strongest wind gust in recorded history, at 408 kilometres (253.5 mi) per hour.
