Mitra papalis, common name the Papal/Pontifical Mitre, is a species of sea snail, a marine gastropod mollusk in the family Mitridae, the miters. [1]

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

Sea snail common name for snails that normally live in saltwater

Sea snail is a common name for snails that normally live in salt water, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Distribution

This marine species is present in India and in the western Indo-Pacific (China, Xisha Islands, Taiwan, Philippines, New Guinea, Fiji, New Caledonia and Guam). [2] [3] [4]

India Country in South Asia

India, also known as the Republic of India, is a country in South Asia. It is the seventh largest country by area and with more than 1.3 billion people, it is the second most populous country as well as the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives, while its Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.

China Country in East Asia

China, officially the People's Republic of China (PRC), is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering approximately 9,600,000 square kilometers (3,700,000 sq mi), it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, and the special administrative regions of Hong Kong and Macau.

Taiwan state in East Asia

Taiwan, officially the Republic of China (ROC), is a state in East Asia. Neighbouring states include the People's Republic of China (PRC) to the west, Japan to the northeast, and the Philippines to the south. Taiwan is the most populous state and largest economy that is not a member of the United Nations (UN).

Habitat

These sea snails live on coral reefs and under rocks, from the intertidal zone to a depth of about 30 m. [4]

Description

Shells of Mitra papalis can reach a length of about 60–166 millimetres (2.4–6.5 in). [2] The form of these large shells is similar to a Papal mitre (hence the common name). They are elongate to ovate, fusiform and smooth but without axial streaks on the surface. Sutural coronations are present. The aperture is moderately wide, smooth within. The shell surface is white, with small white nodules under sutures and with several rows of irregular bright red-orange or purplish blotches. [4]

This species is quite similar to Mitra stictica , but its body form is longer, with more adpressed sutures and wider nodules. [4]
