This is one of the most populated environments in the entire app, there is something to see everywhere and of all sizes.
In the western Atlantic Ocean, cod has a distribution north of Cape Hatteras, North Carolina, and around both coasts of Greenland and the Labrador Sea; in the eastern Atlantic, it is found from the Bay of Biscay north to the Arctic Ocean, including the Baltic Sea, the North Sea, Sea of the Hebrides, areas around Iceland and the Barents Sea.
The largest individual on record was 6 feet (1.8 m) long and weighed 211 lb (96 kg), however usually the cod is between 24 inches (61 cm) and 4 feet (1.2 m) long, and weighs up to 88 lb (40 kg). There is generally no difference in weight or size between sexes of Atlantic Cod.
Atlantic Cod can live for 25 years, and usually attain sexual maturity between ages two and four, although cod in the northeast Arctic can take as long as eight years to fully mature. Colouring is brown or green, with spots on the dorsal side, shading to silver ventrally. A stripe along its lateral line (used to detect vibrations) is clearly visible. Its habitat ranges from the shoreline down to the continental shelf.
Several cod stocks collapsed in the 1990s (declined by >95% of maximum historical biomass) and have failed to fully recover even with the cessation of fishing. This absence of the apex predator has led to a trophic cascade in many areas. Many other cod stocks remain at risk. The Atlantic cod is labelled vulnerable on the IUCN Red List of Threatened Species.

Butterflyfish look like smaller versions of angelfish (Pomacanthidae), but unlike these, lack preopercle spines at the gill covers. Some members of the genus Heniochus resemble the Moorish idol (Zanclus cornutus) of the monotypic Zanclidae. Among the paraphyletic Perciformes, the former are probably not too distantly related to butterflyfish, whereas the Zanclidae seem far less close. Wikipedia
The larger species include the Atlantic blue marlin, Makaira nigricans, which can reach 5 m (16.4 ft) in length and 818 kg (1,803 lb) in weight and the black marlin, Istiompax indica, which can reach in excess of 5 m (16.4 ft) in length and 670 kg (1,480 lb) in weight. They are popular sporting fish in tropical areas. Lien Wikipédia
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 15 to 25 cm (6 to 10 in), with the largest species, Sepia apama, reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) 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.
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. Lien Wikipédia
Portuguese man o' war
The Indo-Pacific Portuguese man-of-war (P. utriculus), or blue bottle, is a related species with very similar appearance found throughout the Indian and Pacific Oceans. Lien Wikipédia
Stingrays are common in coastal tropical and subtropical marine waters throughout the world. Some species, such as Dasyatis thetidis, are found in warmer temperate oceans, and others, such as Plesiobatis daviesi, are found in the deep ocean. The river stingrays, and a number of whiptail stingrays (such as the Niger stingray), are restricted to fresh water. Most myliobatoids are demersal (inhabiting the next-to-lowest zone in the water column), but some, such as the pelagic stingray and the eagle rays, are pelagic.
There are about 220 known stingray species organized into 10 families and 29 genera. Stingray species are progressively becoming threatened or vulnerable to extinction, particularly as the consequence of unregulated fishing. As of 2013, 45 species have been listed as vulnerable or endangered by the IUCN. The status of some other species is poorly known, leading to their being listed as data deficient.
In certain reefs, most notably in the Florida Keys, this beautifully colored fish is commonly spotted among divers and snorkelers. Yellowtails feed on shrimp, crabs, worms, and smaller fish. They spawn in groups off the edges of reefs from spring to fall, but heavily in midsummer.
Yellowtail snapper are typically caught in 30–120 ft of water on and around reefs and other structure. The most common method of catching them is with hook and line, and the use of frozen chum, typically leftover ground fish parts, to attract the fish. The chum is placed into a mesh bag or metal basket in the water, and as the chum slowly melts, small pieces of fish drift out and down towards the bottom, where the yellowtails typically feed. The chum keeps them near the boat for extended periods of time, as well. Light tackle is the generally accepted means of catching yellowtail snapper. Typically, the fish are relatively wary of higher-test or thicker line, and larger hooks. Most fish caught by anglers range from eight to 14 in, although catches to 16 in are not uncommon. Yellowtail snapper can be caught on a variety of baits, including both live and frozen shrimp, squid, and a variety of live and frozen minnows or smaller baitfish. Yellowtail tend to be wary fish, and the appearance of larger predators, such as dolphins or sharks, can scare off schools until the predator leaves the area.
Great White Shark
However most are smaller, males measuring 3.4 to 4.0 m (11 to 13 ft) and females 4.6 to 4.9 m (15 to 16 ft) on average. According to a 2014 study the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates, making it one of the longest lived cartilaginous fish currently known. According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. Great white sharks can swim at speeds of over 56 km/h (35 mph), and can swim to depths of 1,200 m (3,900 ft).
The great white shark has no known natural predators other than, on very rare occasions, the killer whale. The great white shark is arguably the world's largest known extant macropredatory fish, and is one of the primary predators of marine mammals. It is also known to prey upon a variety of other marine animals, including fish and seabirds. It is the only known surviving species of its genus Carcharodon, and is responsible for more recorded human bite incidents than any other shark.
The species faces numerous ecological challenges which has resulted in international protection. The IUCN lists the great white shark as a vulnerable species, and it is included in Appendix II of CITES. It is also protected by several national governments such as Australia (as of 2018).
The novel Jaws by Peter Benchley and the subsequent film by Steven Spielberg depicted the great white shark as a "ferocious man eater". Humans are not the preferred prey of the great white shark, but, nevertheless, the great white is responsible for the largest number of reported and identified fatal unprovoked shark attacks on humans. The great white shark has also been called the white death.
Found in oceans and seas around the world, humpback whales typically migrate up to 25,000 km (16,000 mi) each year. They feed in polar waters, and migrate to tropical or subtropical waters to breed and give birth, fasting and living off their fat reserves. Their diet consists mostly of krill and small fish. Humpbacks have a diverse repertoire of feeding methods, including the bubble net technique.
Like other large whales, the humpback was a target for the whaling industry. Once hunted to the brink of extinction, its population fell by an estimated 90% before a 1966 moratorium. While stocks have partially recovered to some 80,000 animals worldwide, entanglement in fishing gear, collisions with ships and noise pollution continue to impact the species.
