A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. Most seashells are made by mollusks, such as snails, clams, and oysters to protect their soft insides. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have decomposed or been eaten by another organism.
Whelks are any of several carnivorous sea snail species with a swirling, tapered shell. Many are eaten by humans, such as the common whelk of the North Atlantic. Most whelks belong to the family Buccinidae and are known as "true whelks." Others, such as the dog whelk, belong to several sea snail families that are not closely related.

Hebrew spelling refers to the way words are spelled in the Hebrew language. The Hebrew alphabet contains 22 letters, all of which are primarily consonants. This is because the Hebrew script is an abjad, that is, its letters indicate consonants, not vowels or syllables. An early system to overcome this, still used today, is matres lectionis, where four of these letters, alef, he, vav and yud also serve as vowel letters. Later, a system of vowel points to indicate vowels, called niqqud, was developed.
Turritella communis, common name the "common tower shell" is a species of medium-sized sea snails with an operculum, marine gastropod mollusks in the family Turritellidae.
Aporrhais is a genus of medium-sized sea snails, marine gastropod mollusks in the family Aporrhaidae and the superfamily Stromboidea.
Aporrhaidae is a family of sea snails commonly called the "pelican's foot snails." The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005 categorizes Aporrhaidae as marine gastropod mollusks in the clade Littorinimorpha.
Laevistrombus canarium is a species of edible sea snail, a marine gastropod mollusc in the family Strombidae. Known from illustrations in books dating from the late 17th century, L. canarium is an Indo-Pacific species occurring from India and Sri Lanka to Melanesia, Australia and southern Japan. The shell of adult individuals is coloured from light yellowish-brown to golden to grey. It has a characteristic inflated body whorl, a flared, thick outer lip, and a shallow stromboid notch. The shell is valued as an ornament, and because it is heavy and compact, it is also often used as a sinker for fishing nets.
Lottia gigantea, common name the owl limpet, is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Lottiidae. Its genome has been sequenced at the Joint Genome Institute.
