Coelacanths (/ ˈ s iː l ə k æ n θ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2] [3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
A tuna (pl.: tunas or tuna) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae family.The Thunnini comprise 15 species across five genera, [2] the sizes of which vary greatly, ranging from the bullet tuna (max length: 50 cm or 1.6 ft, weight: 1.8 kg or 4 lb) up to the Atlantic bluefin tuna (max length: 4.6 m or 15 ft, weight: 684 kg or 1,508 lb), which ...
Krill(Euphausiids)[ 1 ] (sg.: krill) are small and exclusively marine crustaceans of the order Euphausiacea, found in all the world's oceans. [ 2 ] The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", [ 3 ] which is also often attributed to species of fish. Krill are considered an important trophic level connection ...
Marine life, sea life, or ocean life is the plants, animals, and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon.
Saccopharynx ampullaceus. Saccopharynx ampullaceus, referred to as the gulper eel, gulper, [1] taillight gulper or pelican-fish, is an ocean -dwelling eel found in the North Atlantic Ocean. They are found up to a depth of 3,000 m (9,800 ft). [3][4] These fish are rarely observed, so little information is currently known about their habits or ...
The Atlantic wolffish (Anarhichas lupus), also known as the seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel (the common name for its Pacific relative), woof or sea cat, is a marine fish of the wolffish family Anarhichadidae, native to the North Atlantic Ocean.
The pelican eel's most notable feature is its large mouth, which is much larger than its body. The mouth is loosely hinged, and can be opened wide enough to swallow a fish much larger than the eel itself. The lower jaw is hinged at the base of the head, with no body mass behind it, making the head look disproportionately large.
The young fish will also ride the water into remote semi-landlocked ponds during storms and king tides, where they will stay from one to three years. These ponds, some of which are brackish or freshwater, often become so low in oxygen that tarpons and snooks are the only fish able to survive in these environments. The juveniles therefore face ...
