Pterois is a genus of venomous marine fish, commonly known as lionfish, native to the Indo-Pacific. Pterois, also called zebrafish, firefish, turkeyfish or butterfly-cod, is characterized by conspicuous warning coloration with red, white, creamy, or black bands, showy pectoral fins, and venomous spiky fin rays.Pterois radiata, Pterois volitans, and Pterois miles are the most commonly studied species in the genus. Pterois species are popular aquarium fish.P. volitans and P. miles are a recent and significant invasive species in the west Atlantic and Caribbean Sea.

Film festival

A film festival is an organized, extended presentation of films in one or more cinemas or screening venues, usually in a single city or region. Increasingly, film festivals show some films outdoors. Films may be of recent date and, depending upon the festival's focus, can include international and domestic releases. Some festivals focus on a specific film-maker or genre (e.g., film noir) or subject matter (e.g., horror film festivals). A number of film festivals specialise in short films of a defined maximum length. Film festivals are typically annual events. Some film historians do not consider Film Festivals as official releases of film, like Jerry Beck. The best known film festivals are the Venice Film Festival, the Cannes Film Festival, the Toronto Film Festival, Sundance Film Festival, and the Berlin International Film Festival, the latter being the largest film festival worldwide, based on attendance. The Venice Film Festival is the oldest major festival. The Melbourne International Film Festival is the largest film festival in the Southern Hemisphere and one of the oldest in the world. A 2013 study found 3,000 active films festivals worldwide—active defined as having held an event in the previous 24 months.

Gulf of Mexico

The Gulf of Mexico (Spanish: Golfo de México) is an ocean basin largely surrounded by the North American continent. as well as Central America. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast" in comparison with the U.S. Atlantic and Pacific coasts, or sometimes the "south coast", in juxtaposition to the Great Lakes region being the "north coast."

The Gulf of Mexico formed approximately 300 million years ago as a result of plate tectonics. The Gulf's basin is roughly oval and is approximately 810 nautical miles (1,500 km; 930 mi) wide and floored by sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Florida Straits between the U.S. and Cuba, and with the Caribbean Sea (with which it forms the American Mediterranean Sea) via the Yucatan Channel between Mexico and Cuba. With the narrow connection to the Atlantic, the Gulf experiences very small tidal ranges. The size of the Gulf basin is approximately 1.6 million km² (615,000 sq mi). Almost half of the basin is shallow continental shelf waters. The basin contains a volume of roughly 2500 quadrillion litres (550 quadrillion Imperial gallons, 660 US quadrillion gallons, 2.5 million cu km or 600,000 cu mi).

Atlantic Ocean

The Atlantic Ocean is the second largest of the world's oceanic divisions, following the Pacific Ocean. With a total area of about 106,400,000 square kilometres (41,100,000 sq mi), it covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. The first part of its name refers to Atlas of Greek mythology, making the Atlantic the "Sea of Atlas".

The oldest known mention of "Atlantic" is in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): Atlantis thalassa (Greek: Ἀτλαντὶς θάλασσα; English: Sea of Atlas). The term Ethiopic Ocean, derived from Ethiopia, was applied to the southern Atlantic as late as the mid-19th century. Before Europeans discovered other oceans, their term "ocean" was synonymous with the waters beyond the Strait of Gibraltar that are now known as the Atlantic. The early Greeks believed this ocean to be a gigantic river encircling the world.

The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. As one component of the interconnected global ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The equator subdivides it into the North Atlantic Ocean and South Atlantic Ocean.
