Squid Superorder of cephalopod molluscs

A squid is a mollusc with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius or pen, made of chitin.

Cephalopod Class of mollusks

A cephalopod is any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.

Flatfish Order of fishes

A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward.

Scripps Institution of Oceanography Center for ocean and Earth science research

The Scripps Institution of Oceanography in San Diego, California, founded in 1903, is one of the oldest and largest centers for ocean and Earth science research, public service, undergraduate and graduate training in the world. Hundreds of ocean and Earth scientists conduct research with the aid of oceanographic research vessels and shorebased laboratories. Its Old Scripps Building is a U.S. National Historic Landmark. SIO is a division of the University of California San Diego (UCSD). The public explorations center of the institution is the Birch Aquarium at Scripps. Since becoming part of the University of California in 1912, the institution has expanded its scope to include studies of the physics, chemistry, geology, biology, and climate of Earth.

Marine Biological Laboratory Research institution in Woods Hole, Massachusetts

The Marine Biological Laboratory (MBL) is an international center for research and education in biological and environmental science. Founded in Woods Hole, Massachusetts, in 1888, the MBL is a private, nonprofit institution affiliated with the University of Chicago. After being independent for most of its history, it became officially affiliated with the university on July 1, 2013. It also collaborates with numerous other institutions.

The Empire of Man is a series of science fiction books by David Weber and John Ringo published by Baen Books. It combines elements of space opera and military science fiction.

Wobbegong Family of sharks

The wobbegong is the common name given to the 12 species of carpet sharks in the family Orectolobidae. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan. The word wobbegong is believed to come from an Australian Aboriginal language, meaning "shaggy beard", referring to the growths around the mouth of the shark of the western Pacific.

<i>Carcinus maenas</i> Species of crab

Carcinus maenas is a common littoral crab. It is known by different names around the world. In the British Isles, it is generally referred to as the shore crab, or green shore crab. In North America and South Africa, it bears the name green crab. European green crab is a similar, but distinct species.

Hopkins Marine Station is the marine laboratory of Stanford University. It is located ninety miles south of the university's main campus, in Pacific Grove, California on the Monterey Peninsula, adjacent to the Monterey Bay Aquarium. It is home to ten research laboratories and a fluctuating population of graduate and undergraduate students. It has also been used for archaeological exploration, including of the Chinese-American fishing village that existed on the site before burning down in 1906.

Common cuttlefish Species of cephalopod

The common cuttlefish or European common cuttlefish is one of the largest and best-known cuttlefish species. They are a migratory species that spend the summer and spring inshore for spawning and then move to depths of 100 to 200m during autumn and winter. They grow to 49 cm in mantle length (ML) and 4 kg in weight. Animals from subtropical seas are smaller and rarely exceed 30 cm in ML.

Pharaoh cuttlefish Species of cephalopods

The pharaoh cuttlefish is a large cuttlefish species, growing to 42 cm in mantle length and 5 kg in weight. It is also known as seiche pharaon.

Roger Arliner Young American zoologist

Roger Arliner Young was an American scientist of zoology, biology, and marine biology. She was the first African American woman to receive a doctorate degree in zoology.

<i>Octopus cyanea</i> Species of cephalopod known as the big blue octopus

Octopus cyanea, also known as the big blue octopus or day octopus, is an octopus in the family Octopodidae. It occurs in both the Pacific and Indian Oceans, from Hawaii to the eastern coast of Africa. O. cyanea grows to 16 cm in mantle length with arms to at least 80 cm. This octopus was described initially by the British zoologist John Edward Gray in 1849; the type specimen was collected off Australia and is at the Natural History Museum in London.

Plate fish Species of fish

The plate fish is a flounder in the genus Bothus, found in the warmer parts of the Atlantic including the Caribbean. Its typical habitat is sandy plains near coral reefs and it is able to change its colouring to make it well-camouflaged in this environment. It is sometimes known as the peacock flounder, a name also given to the closely related Bothus mancus from the Indo-Pacific.

Cuttlefish Order of molluscs

Cuttlefish or cuttles are marine molluscs 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, which is used for control of buoyancy.

Multi-Terrain Pattern

The Multi-Terrain Pattern (MTP) is the standard camouflage pattern of the British Armed Forces.

Underwater camouflage Camouflage in water, mainly by transparency, reflection, counter-illumination

Underwater camouflage is the set of methods of achieving crypsis—avoidance of observation—that allows otherwise visible aquatic organisms to remain unnoticed by other organisms such as predators or prey.

<i>Macrotritopus defilippi</i> Species of mollusc

Macrotritopus defilippi, commonly known as the Lilliput longarm octopus or the Atlantic longarm octopus, is a small species of octopus, a marine cephalopod mollusc of the order Octopoda.

Coincident disruptive coloration Camouflage joining up separate parts of body

Coincident disruptive coloration or coincident disruptive patterns are patterns of disruptive coloration in animals that go beyond the usual camouflage function of breaking up the continuity of an animal's shape, to join up parts of the body that are separate. This is seen in extreme form in frogs such as Afrixalus fornasini where the camouflage pattern extends across the body, head, and all four limbs, making the animal look quite unlike a frog when at rest with the limbs tucked in.
