Lyncina lynx
A common cowry with highly variable, spotted shells.
Lyncina lynx, called the lynx cowry or eyed cowry, is a sea snail, a marine gastropod mollusk belonging to the cowry family Cypraeidae. This species is fairly common, and its shells vary greatly in both pattern and size. Shells typically measure 38 to 50 mm in length, though they can be as small as 18 mm or as large as 90 mm. The smooth, shiny upper surface is usually pale brown, pale purple, or grey, densely dotted with small and large dark brown or purple spots; the larger spots extend to the shell’s edges. The underside is white or pale brown, and the long, narrow opening has several white teeth with bright reddish gaps between them. In living animals, the mantle is transparent, bearing white, tree-shaped sensory papillae, and it can cover the entire shell.
This cowry is found in the Red Sea, the Indian Ocean off southeastern Africa (including Aldabra, Chagos, Kenya, Madagascar, the Mascarene Basin, Mauritius, Réunion, the Seychelles, Zanzibar, and Tanzania), and the western Pacific Ocean (the Philippines, Japan, Taiwan, western and northern Australia, Polynesia, and Hawaii). It lives in tropical shallow water, in subtidal and intertidal zones, usually under rocks or corals down to about 10 meters deep. It begins feeding at dusk, mainly on sponges.
Several subspecies have been described: Cypraea lynx var. williamsi, Cypraea (Luponia) lynx globosa, Cypraea lynx var. michaelis, Cypraea lynx var. incrassata, Lyncina lynx pacifica, and Cypraea (Lyncina) lynx var. javana.

Lore & Background
The shells of Lyncina lynx are smooth and shiny, with a dorsum surface that is generally pale brown, pale purple, or grey, densely covered with small and large dark brown or purple dots. The large spots extend to the edges. The base is white or pale brown, and the aperture is long and narrow, with several white teeth and a bright reddish spacing. In living specimens, the mantle is transparent, with tree-shaped white sensorial papillae, and may cover the entire shell.
This species occurs in the Red Sea, the Indian Ocean along South-East Africa (including Aldabra, Chagos, Kenya, Madagascar, the Mascarene Basin, Mauritius, Réunion, the Seychelles, Zanzibar, and Tanzania), and the western Pacific Ocean (Philippines, Japan, Taiwan, western and northern Australia, Polynesia, and Hawaii). It lives in tropical shallow water, subtidal and intertidal, usually under rocks or corals up to about 10 m of depth, and begins feeding at dusk, mainly on sponges.
Several subspecies and varieties have been described, including Cypraea lynx var. williamsi, Cypraea (Luponia) lynx globosa, Cypraea lynx var. michaelis, Cypraea lynx var. incrassata, Lyncina lynx pacifica, and Cypraea (Lyncina) lynx var. javana.
Reader's Guide
Lyncina lynx is a widely distributed and common cowry, notable for the striking variability in its shell pattern and size. The dense covering of dark dots on a pale background, combined with the bright reddish spacing between the white teeth of the aperture, makes it easily recognizable. Its presence across a vast range—from the Red Sea and Indian Ocean to the western Pacific—reflects its adaptability to tropical shallow waters. The species' habit of feeding at dusk on sponges and its preference for hiding under rocks or corals are typical of many cowries. The numerous described subspecies and varieties indicate a long history of taxonomic interest, though the species itself remains well-defined. Its common names, lynx cowry and eyed cowry, likely refer to the spotted pattern reminiscent of a lynx's coat or eyes. As a common and variable species, it is frequently encountered in collections and serves as a representative example of the family Cypraeidae.
