The record size ocean sunfish crashed into a boat off Bird Island, Australia in 1910 and measured 4.3 m (14 ft) from fin-to-fin, 3.1 m (10 ft) in length and weighed about 2,300 kg (5,100 lb), [1] while the other record for the biggest bony fish is yet held by a Mola alexandrini which was also coincidentally 2,300 kg (5,100 lb) in mass and 3 m ...
Divers have observed that despite the fish’s small size, typically between 6 and 10 inches, its territorial aggression and jaw-flaring display can be deceptively intense during encounters. [8] Neoclinus Blanchard exhibits significant mobility of the maxilla due to its conical shape and deep socket. [ 11 ]
Nomura's jellyfish (エチゼンクラゲ, echizen kurage, Nemopilema nomurai) is a very large rhizostome jellyfish, in the same size class as the lion's mane jellyfish, the largest cnidarian in the world. It is edible but not considered high quality. [1] It is the only species in the monotypic genus Nemopilema.
The wahoo is perhaps the fastest fish for its size, attaining a speed of 19 lengths per second, reaching 78 kilometres per hour (48 mph). Flying fish Their glides are typically around 50 meters (160 ft), but they can use updrafts at the leading edge of waves to cover distances of at least 400 meters (1,300 ft). [ 114 ]
The body is kept relatively rigid and there is very little motion of the center of mass motion during locomotion compared to the body size of the fish. [8] The caudal fin is absent, or in the apteronotids, greatly reduced. The gill opening is restricted. The anal opening is under the head or the pectoral fins. [11]
Genetic testing was performed on Methuselah in 2023 to estimate her age by measuring DNA methylation from a sample of her fins. [10] The study estimated her to be between 92 and 101 years old at the time, far upwards of her previously estimated age of 84. [5] By comparison, the aquarium's two other lungfish were found to be 54 and 50 years old ...
Capture (blue) and aquaculture (green) production of Channa micropeltes in thousand tonnes from 1950 to 2022, as reported by the FAO [2]. Channa micropeltes, giant snakehead, giant mudfish or toman harimau, is among the largest species in the family Channidae, capable of growing to 1.3 m (4.3 ft) in length and a weight of 20 kg (44 lb).

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.
