This species is common within its range in the tropical Western Atlantic, but it is often not noticed, because its color and texture are similar to the rocks on which it lives.
In countries that used to be part of the British West Indies, these and other common intertidal chitons are known as "curb"; the foot of the animal is eaten by people and is also used as bait for fishing.

The surface of the valves (or plates) in this species is almost always heavily eroded in adults, but when not eroded, the valve surface is granulated. The valves are thick and heavy.
Acanthopleura is a genus of chitons in the family Chitonidae. In this genus the girdle is spiny or spiky. It has eight described species at present.Atlantic surf clam
The Atlantic surf clam (Spisula solidissima), also called the bar clam, hen clam, skimmer, or simply sea clam, is a very large, edible, saltwater clam or marine bivalve mollusk in the family Mactridae. It is commonly found in the western Atlantic Ocean. Reaching up to 20 centimetres (7.9 in) or more in length, it is much larger than the related surf clam, which resides in the eastern Atlantic waters off of Great Britain.
The shell of this species is a well-known object to beach-goers in the northeastern United States. People on the beach often pick up a large empty shell of this species, either to dig in the sand with, or take home to use as a decorative dish or ashtray.
The species is exported commercially as a food item.Chiton
Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
They are also sometimes known as sea cradles or "coat-of-mail shells", or more formally as loricates, polyplacophorans, and occasionally as polyplacophores.
Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle.Flora and Fauna of Honduras
The flora and fauna of Honduras reflects the country's geographical location inside the tropics. This has allowed for diverse species of plants and animals to be adapted, but some of them are now in danger of extinction. This has posed the Honduran government, offices and nature organizations to look after the protection of the local environment, like the creation of nature reserves.Giant Pacific octopus
The giant Pacific octopus (Enteroctopus dofleini), also known as the North Pacific giant octopus, is a large marine cephalopod belonging to the genus Enteroctopus. Its spatial distribution includes the coastal North Pacific, along California, Oregon, Washington, British Columbia, Alaska, Russia, Japan, and Korean Peninsula. It can be found from the intertidal zone down to 2,000 m (6,600 ft), and is best adapted to cold, oxygen-rich water. It is the largest octopus species, based on a scientific record of a 71-kg (156-lb) individual weighed live.List of edible molluscs
This is a partial list of edible molluscs. Molluscs are a large phylum of invertebrate animals, many of which have shells. Edible molluscs are harvested from saltwater, freshwater, and the land, and include numerous members of the classes Gastropoda (snails), Bivalvia (clams, scallops, oysters etc.), Cephalopoda (octopus and squid), and Polyplacophora (chitons).
A large number of different species of molluscs are eaten worldwide, either cooked or raw. Some mollusc species are commercially exploited and shipped as part of the international trade in shellfish; other species are harvested, sold and consumed locally. Some species are collected and eaten locally but are rarely bought and sold. A few species of molluscs are not commonly eaten now, but were eaten in historical or prehistoric times.
The list is divided into marine and non-marine (terrestrial and freshwater) species, and within those divisions, the lists are primarily arranged taxonomically, so that related species are grouped together.List of marine molluscs of Venezuela
The marine molluscs of Venezuela are a part of the molluscan fauna of Venezuela. The marine molluscs are the snails, clams and mussels, chitons, octopuses, squid and cuttlefish; that live in marine and estuarine habitats. The freshwater and land molluscs are not included in this list.
This is a partial list of the marine molluscs of Venezuela. The families are listed alphabetically within the classes.List of molluscs of Falcón State, Venezuela
Falcón State is a state on the coast in the northwestern part of the country of Venezuela. Falcón State covers a total surface area of 24,800 km² and, in 2010, had an estimated population of 950,057. There are four national parks in the state: the Médanos de Coro National Park, the Cueva de la Quebrada del Toro, Morrocoy, and Juan Crisóstomo Falcón National Park.
A large number of species of terrestrial, freshwater and marine molluscs are found in the wild in Falcón State. However, most of the marine mollusks in the area are the same species that occur elsewhere in the Caribbean faunal zone.
This is a partial list of the molluscs of Falcón State. The families are listed alphabetically within the classes. Whether the family is marine, terrestrial or freshwater is indicated after the name of the family, but there is no attempt to separate marine species from non-marine species.Perna canaliculus
The New Zealand green-lipped mussel (Perna canaliculus), also known as the New Zealand mussel, the greenshell mussel, kuku, and kutai, is a bivalve mollusc in the family Mytilidae (the true mussels). P. canaliculus has economic importance as a cultivated species in New Zealand.Semiaquatic
In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water. Examples are given below.Snail caviar
Snail caviar, also known as escargot caviar or escargot pearls, is a type of caviar that consists of fresh or processed eggs of land snails.
In their natural state, the eggs are colourless. After processing, the caviar may be cream-coloured, pinkish-white, or white, with the eggs generally 3–4 mm in diameter. Some snail eggs may measure at 3–6 mm in diameter. Some commercial snail farms that produce escargot include the production of snail caviar as a part of their operations.Visual system
The visual system is the part of the central nervous system which gives organisms the ability to process visual detail as sight, as well as enabling the formation of several non-image photo response functions. It detects and interprets information from visible light to build a representation of the surrounding environment. The visual system carries out a number of complex tasks, including the reception of light and the formation of monocular representations; the buildup of a nuclear
binocular perception from a pair of two dimensional projections; the identification and categorization of visual objects; assessing distances to and between objects; and guiding body movements in relation to the objects seen. The psychological process of visual information is known as visual perception, a lack of which is called blindness. Non-image forming visual functions, independent of visual perception, include the pupillary light reflex (PLR) and circadian photoentrainment.
This article mostly describes the visual system of mammals, humans in particular, although other "higher" animals have similar visual systems (see bird vision, vision in fish, mollusc eye, and reptile vision).
