The Registry of World Record Size Shells is a conchological work listing the largest (and in some cases smallest) verified shell specimens of various marine molluscan taxa.A successor to the earlier World Size Records of Robert J. L. Wagner and R. Tucker Abbott, it has been published on a semi-regular basis since 1997, changing ownership and publisher a number of times.
Tonna galea, commonly known as the giant tun, is a species of marine gastropod mollusc in the family Tonnidae (also known as the tun shells). This very large sea snail or tun snail is found in the North Atlantic Ocean as far as the coast of West Africa, in the Mediterranean Sea and the Caribbean Sea.
It refers to the shell of a large sea snail from the Indian Ocean (a shell of the species Turbinella pyrum), but one that has a rare reverse-turning spiral. The shankha is held with the spout (siphonal canal) pointed up; its spiral twists rightwards rather than the more common form, which twists leftwards.

This list of marine gastropod genera in the fossil record is an attempt to list all the genera of sea snails or marine gastropod mollusks which have been found in the fossil record. Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell ( sea slugs ) to leave any recognizable traces.
They come in all shapes and sizes. Some walk, some slither, some fly and some swim. Humans are blessed to share the planet with just over 2.1 million recognized species of animals. And scientists ...
The genus name Xenophora comes from two ancient Greek words and means "bearing (or carrying) foreigners". The shells are small to rather large (diameter of base without attachments 19–160 mm; height of shell 21–100 mm), depressed to conical, with narrow to wide, simple to spinose peripheral edge or flange separating spire from base.
The fish spotted by oceangoers on August 10 was 12 feet long, according to the institution. The fish had already died at the time of the discovery, and was found near the shores of La Jolla Cove.
