WAcropora aculeus is a species of acroporid corals found throughout the Indian Ocean, the central Indo-Pacific, Australia, southeast Asia, Japan and the East China Sea. It is also present in the western Pacific Ocean. It is an uncommon species and is particularly prone to coral bleaching, disease, and crown-of-thorns starfish predation; it is also harvested for use in aquaria, and the International Union for Conservation of Nature has assessed it as being a "vulnerable species". Habitat loss is a big concern.
WAcropora cerealis is a species of acroporid coral found throughout the Indian and Pacific oceans, from the Red Sea and the Gulf of Aden to the Hawaiian Islands and the Johnston Atoll. It can be found on upper reef slopes in shallow tropical reefs, from depths of 3–20 m. Crown-of-thorns starfish preferentially prey upon Acropora corals, and this species is also harvested for the aquarium trade.
WAcropora echinata is a species of acroporid coral that was first described by Dana in 1846. Found in shallow, tropical, sheltered reefs in marine environments, it is found at depths of 8 to 25 m in clear water. The species is listed as vulnerable on the IUCN Red List, and has a decreasing population. It is not common but found over a large area, and is listed under CITES Appendix II.
WAcropora horrida is a species of acroporid coral that was first described by James Dwight Dana in 1846. Found in tropical, shallow reefs in marine environments, it occurs near fringing reefs around turbid water, at depths of 5 to 20 m. It is listed as a vulnerable species on the IUCN Red List, and it is thought to have a decreasing population. It is not common and found over a large area, and is listed under CITES Appendix II.
WAntarctic krill is a species of krill found in the Antarctic waters of the Southern Ocean. It is the dominant animal species of Earth. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic metre. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their pelagic life cycle. It grows to a length of 6 centimetres (2.4 in), weighs up to 2 grams (0.071 oz), and can live for up to six years. It is a key species in the Antarctic ecosystem and in terms of biomass, is one of the most abundant animal species on the planet.

This crab primarily eats sea lettuce and other green algae, and occasionally scavenges dead animals.
WDipsastraea pallida is a species of colonial stony coral in the family Merulinidae. It is found in tropical waters of the Indian and Pacific Oceans. This is a common species of coral with a widespread distribution, and the main threat it faces is from the destruction of its coral reef habitats. It is rated as a "least-concern species" by the International Union for Conservation of Nature. This species was first described in 1846 as Favia pallida by the American zoologist James Dwight Dana; it was later transferred to the genus Dipsastraea, but some authorities continue to use the original name.

WLobsters are a family of large marine crustaceans.
WThe graceful rock crab or slender crab, Metacarcinus gracilis or Cancer gracilis, is one of only two members of the genus Metacarcinus, recognized by WoRMS, whose chelae (claws) are white tipped, the other crab being M. magister. Both of these eastern Pacific crab species are recognized by ITIS as belonging to the much larger genus Cancer. M. gracilis has been caught from Alaska to Bahía Magdelena, Baja California. Although M. gracilis is only found in the Pacific Ocean, it has cousins in the Atlantic Ocean. The genus Cancer apparently evolved in the Pacific Ocean and later migrated to the Atlantic Ocean. Larvae and small juveniles of this species are often seen riding jellyfish, especially Phacellophora camtschatica. The juvenile crabs steal food from the jellyfish and also clean off parasitic amphipods.

WNephropoidea is a superfamily of decapod crustaceans. It contains the true lobsters in the Nephropidae, and three fossil families: Chilenophoberidae, Protastacidae and Stenochiridae. Their closest relatives are the reef lobsters.
WOregonia gracilis, commonly known as the graceful decorator crab, is a species of crab belonging to the family Oregoniidae. Like other decorator crabs it habitually attaches other organisms to its back. The sessile organisms are attached to hooked setae that act as a sort of velcro attachment. This decoration provides visual and chemical camouflage thus reducing predation risk. Pacific halibut are a major predator of O. gracilis. Other predators include octopus and sea otters. The main food source of O. gracilis is floating kelp and algae that they capture utilizing a waiting strategy in order to maintain cryptosis.

It was introduced to Europe in the 1960s to supplement the North European Astacus astacus fisheries, which were being damaged by crayfish plague, but the imports turned out to be a carrier of that disease. The signal crayfish is now considered an invasive species across Europe, Japan, and California ousting native species there.
WTemora stylifera is a copepod primarily found in the Atlantic and surrounding waters.
WTemora turbinata is a copepod in the Temoridae family. It is an epipelagic species, having been recorded in coastal waters around the world. It was first described in 1849 by American scientist James Dwight Dana.
