Charonia tritonis, common name for the Triton's trumpet or the giant triton, is a species of very large sea snail, a marine gastropod mollusc in the family Charoniidae, the tritons. Reaching up to two feet (or 60 cm) in shell length this is one of the biggest mollusks in the coral reef. This species is found throughout the Indo-Pacific Oceans, Red Sea included.

The common name "Triton's trumpet" is derived from the Greek god Triton, who was the son of Poseidon, god of the sea. The god Triton is often portrayed blowing a large seashell horn similar to this species.

The shell is well known as a decorative object, and is sometimes modified for use as a trumpet (such as the Japanese horagai, the Maldivian sangu or the Māori pūtātara).

C. tritonis is one of the few animals to feed on the crown-of-thorns starfish, Acanthaster planci. Occasional plagues of this large and destructive starfish have killed extensive areas of coral on the Great Barrier Reef of Australia and the western Pacific reefs. The triton has been described as tearing the starfish to pieces with its file-like radula.

Much debate has occurred on whether plagues of crown-of-thorns starfish are natural or are caused by overfishing of the few organisms that can eat this starfish, including C. tritonis. In 1994, Australia proposed that C. tritonis should be put on the CITES list, thereby attempting to protect the species. Because of a lack of trade data concerning this seashell, the Berne Criteria from CITES were not met, and the proposal was consequently withdrawn. While this species may be protected in Australia and other countries (such as India), it can be legally traded and is found for sale in many shell shops around the world and on the internet.


The reef knot, or square knot, is an ancient and simple binding knot used to secure a rope or line around an object. It is sometimes also referred to as a Hercules knot. The knot is formed by tying a left-handed overhand knot and then a right-handed overhand knot, or vice versa. A common mnemonic for this procedure is "right over left; left over right", which is often appended with the rhyming suffix "... makes a knot both tidy and tight". Two consecutive overhands of the same handedness will make a granny knot. The working ends of the reef knot must emerge both at the top or both at the bottom, otherwise a thief knot results.

The reef knot or square knot consists of two half knots, one left and one right, one being tied on top of the other, and either being tied first...The reef knot is unique in that it may be tied and tightened with both ends. It is universally used for parcels, rolls and bundles. At sea it is always employed in reefing and furling sails and stopping clothes for drying. But under no circumstances should it ever be tied as a bend, for if tied with two ends of unequal size, or if one end is stiffer or smoother than the other, the knot is almost bound to spill. Except for its true purpose of binding it is a knot to be shunned.

— The Ashley Book of Knots[1]
The reef knot is not recommended for tying two ropes together, because of the potential instability of the knot; something that has resulted in many deaths (see Misuse as a bend).

The reef knot is used to tie the two ends of a single rope together such that they will secure something, for example a bundle of objects, that is unlikely to move much. In addition to being used by sailors for reefing and furling sails, it is also one of the key knots of macrame textiles.[8]

The knot lies flat when made with cloth and has been used for tying bandages for millennia. As a binding knot it was known to the ancient Greeks as the Hercules knot (Herakleotikon hamma) and is still used extensively in medicine.[9] In his Natural History, Pliny relates the belief that wounds heal more quickly when bound with a Hercules knot.[10]

It has also been used since ancient times to tie belts and sashes. A modern use in this manner includes tying the obi (or belt) of a martial arts keikogi.

With both ends tucked (slipped) it becomes a good way to tie shoelaces, whilst the non-slipped version is useful for shoelaces that are excessively short. It is appropriate for tying plastic garbage or trash bags, as the knot forms a handle when tied in two twisted edges of the bag.

The reef knot figures prominently in Scouting worldwide. It is included in the international membership badge[11] and many scouting awards.[12] In the Boy Scouts of America demonstrating the proper tying of the square knot is a requirement for all boys joining the program.[13] In Pioneering (Scouting), it is commonly used as a binding knot to finish off specialized lashing (ropework) and whipping knots.[14] However, it is an insecure knot, unstable when jiggled, and is not suitable for supporting weight.

A surgeon's variation, used where a third hand is unavailable, is made with two or three twists of the ropes on bottom, and sometimes on top, instead of just one.
