An islet is a very small, often unnamed
island. Most definitions are not precise, but some suggest that an islet has little or no
vegetation and cannot support
human habitation. It may be made of rock, sand and/or
hard coral; may be permanent or tidal (i.e. surfaced
reef or
seamount); and may exist in the
sea,
lakes,
rivers or any other sizeable
bodies of water.
Definition
As suggested by its origin islette, an
Old Frenchdiminutive of "isle",[1] use of the term implies small size, but little attention is given to drawing an upper limit on its applicability.
The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size.[2]
Other terms
Ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/), a small island. It is especially used to refer to river islands found on the
River Thames and its tributaries in England.[3][4][5]
Cay or key, an islet formed by the accumulation of fine sand deposits atop a
reef, especially in the
Caribbean and West Atlantic.
Rum Cay in the
Bahamas and the
Florida Keys off
Florida are examples of islets.
Rock, in the sense of a type of islet, is an uninhabited landform composed of exposed
rocks, lying offshore, and having at most minimal vegetation, such as
Albino Rock in the
Palm Island group off
Queensland, Australia.
Sea stack, a thin, vertical landform jutting out of a body of water.
Skerry, a small rocky island, usually defined to be too small for habitation, especially in
Ireland.
Subsidiary islets, a more technical application, is applied to small land features isolated by water, lying off the shore of a larger island. Similarly, any emergent land in an atoll is also called an islet.[8]
Tidal island, small islands (not always islets) which lie closely off the coast of a
mainland or a much larger island, being connected to it (and thus becomes a
peninsula/
promontory) in low tide and isolated by a
channel in high tide.
The
International Court of Justice jurisprudence however sometimes ignores islets, regardless of inhabitation status, in deciding territorial disputes; it did so in 2009 in adjudicating the
Romania-Ukraine dispute, and previously in the dispute between Libya and Malta involving the islet of
Filfla.[9][12]
List of islets
There are thousands of islets on Earth: approximately 24,000 islands and islets in the
Stockholm archipelago alone. The following is a list of example islets from around the world.
