Mollusc eye

+ Save concept

The molluscs have the widest variety of eye morphologies of any phylum, and a large degree of variation in their function. [1]

Aesthete (chiton)

Aesthetes are organs in chitons, derived from the mantle of the organism..

Arthropod eye

Apposition eyes are the most common form of eye, and are presumably the ancestral form of compound eye.

Cephalopod

A cephalopod is any member of the molluscan class Cephalopoda (Greek plural κεφαλόποδα, kephalópoda; "head-feet") such as a squid, octopus or nautilus.

Cuttlefish

Cuttlefish or cuttles are marine animals of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone. Despite their name, cuttlefish are not fish but molluscs. Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from, with the largest species, Sepia apama, reaching in mantle length and over in mass. Cuttlefish eat small molluscs, crabs, shrimp, fish, octopus, worms, and other cuttlefish. Their predators include dolphins, sharks, fish, seals, seabirds, and other cuttlefish. The average life expectancy of a cuttlefish is about one to two years. Recent studies indicate cuttlefish are among the most intelligent invertebrates. (television program) NOVA, PBS, April 3, 2007. Cuttlefish also have one of the largest brain-to-body size ratios of all invertebrates. The 'cuttle' in 'cuttlefish' comes from the Old English name for the species, cudele, which may be cognate with the Old Norse koddi ('cushion') and the Middle Low German Kudel ('rag'). The Greco-Roman world valued the cuttlefish as a source of the unique brown pigment the creature releases from its siphon when it is alarmed. The word for it in both Greek and Latin, sepia, now refers to the reddish-brown color sepia in English.

Mollusca

Mollusca is a large phylum of invertebrate animals whose members are known as molluscs or mollusksThe formerly dominant spelling mollusk is still used in the U.S. — see the reasons given in Gary Rosenberg's.

Nautilus

The nautilus (from the Latin form of the original ναυτίλος, 'sailor') is a pelagic marine mollusc of the cephalopod family Nautilidae, the sole extant family of the superfamily Nautilaceae and of its smaller but near equal suborder, Nautilina.

Sensory organs of gastropods

The sensory organs of gastropods (snails and slugs) include olfactory organs, eyes, statocysts and mechanoreceptors.

Simple eye in invertebrates

A simple eye (sometimes called a pigment pit) refers to a type of eye form or optical arrangement that contains a single lens.

Squid

Squid are cephalopods of the two orders Myopsida and Oegopsida, which were formerly regarded as two suborders of the order Teuthida, however recent research shows Teuthida to be paraphyletic.

Vision in fishes

Vision is an important sensory system for most species of fish.

Visual system

The visual system is the part of the central nervous system which gives organisms the ability to process visual detail, as well as enabling the formation of several non-image photo response functions.
