Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
The earliest known sea cows, of the families †Prorastomidae and †Protosirenidae, were both confined to the Eocene, and were pig-sized, four-legged, amphibious creatures. [19] The first members of Dugongidae appeared by the middle Eocene. [20] At this point, sea cows were fully aquatic. [19] Pinnipeds split from other caniforms 50 mya during ...
Most deep sea pelagic fishes belong to their own orders, suggesting a long evolution in deep sea environments. In contrast, deep water benthic species, are in orders that include many related shallow water fishes. [71] The umbrella mouth gulper is a deep sea eel with an enormous loosely hinged mouth. It can open its mouth wide enough to swallow ...
The five oceans could easily be considered the last frontier on the planet. Crucial to the world’s ecosystems, approximately 80% of the earth’s oceans are unmapped and unexplored. The Atlantic ...
The “connection” between the two might have to do with the fact that the shimmery creature typically lives in the deep sea, dwelling anywhere between 700 and 3,280 feet below the surface, USA ...
Evolutionary theory says all animals that are walking on land actually evolved from sea-dwelling creatures at some point in the ancient past. To study this further, scientists from McGill ...
Many eels, both reef, benthic, and deep-sea, nocturnally migrate to the surface layer as larvae. [64] But while the ocean's surface may seem like an odd habitat for larval deep-sea fish, they are far from the most unusual. Diverse fish that migrate into freshwater as adults (either as a habitat or spawning ground) rely on the neuston when young.
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish , cookiecutter shark , bristlemouths , anglerfish , viperfish , and some species of eelpout .
