Deep-sea chimaera photographed by the NOAAS Okeanos Explorer.Visible on its snout are tiny pores which lead to electroreceptor cells.. Chimaeras are soft-bodied, shark-like fish with bulky heads and long, tapered tails; measured from the tail, they can grow up to 150 cm (4.9 ft) in length.
The spawn (eggs) of a clownfish. The black spots are the developing eyes. Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and ...
The composition of the abyssal plain depends on the depth of the sea floor. Above 4000 meters the seafloor usually consists of calcareous shells of foraminifera, zooplankton , and phytoplankton . At depths greater than 4000 meters shells dissolve, leaving behind a seafloor of brown clay and silica from dead zooplankton and phytoplankton. [ 3 ]
Some particular types of migration are anadromous, in which adult fish live in the sea and migrate into fresh water to spawn; and catadromous, in which adult fish live in fresh water and migrate into salt water to spawn. [2] Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are ...
The giant cuttlefish (Sepia apama), also known as the Australian giant cuttlefish, [3] is the world's largest cuttlefish species, growing to 50 cm (20 in) in mantle length and up to 100 cm (39 in) in total length (total length meaning the whole length of the body including outstretched tentacles).
The abyssal grenadier, Coryphaenoides armatus, is an abyssal fish of the genus Coryphaenoides, found in all the world's oceans, at depths between 800 and 5,493 metres (2,625 and 18,022 ft). [3] Its adult length is 20 to 40 centimetres (8 to 16 in), although Fishbase [2] gives lengths up to 1 metre (3 ft 3 in). The abyssal grenadier's body is ...
The community composition varies with depths in the mesopelagic as different organisms are evolved for varying light conditions. [8] Microbial biomass in the mesopelagic is greater at higher latitudes and decreases towards the tropics, which is likely linked to the differing productivity levels in the surface waters. [ 8 ]
In the Adriatic Sea, European squid can be found above various substrates, from sandy through to the muddy bottoms. [4] It is found in temperatures of 13°C–20°C, preferring 18°C. [5] L. vulgaris is found throughout the Mediterranean and in the eastern Atlantic Ocean from the North Sea to the Gulf of Guinea.
