The unusual high brain energy consumption percentage of mormyrinae fish is thus due to them having the unusual combination of a large brain in a low energy consuming body. [1] The actual energy consumption per unit mass of its brain is not in fact particularly high and indeed lower (2.02 mg g 1 h 1 ) than that in some other fish such as ...
The Mormyridae, sometimes called "elephantfish" (more properly freshwater elephantfish), are a superfamily of weakly electric fish in the order Osteoglossiformes native to Africa. [1] It is by far the largest family in the order, with around 200 species. Members of the family can be popular, if challenging, aquarium species.
The brain of this superfamily is one of the largest among fishes and has a body-proportional size comparable to that of humans, [31] with a brain-to-body mass ratio ranging from 1/52 to 1/82, and possibly associated with the ability to interpret bioelectrical signals. [32]
Omega-3 fatty acids are a type of polyunsaturated fat shown to have benefits to brain and heart health. There are two types of omega-3s: plant-based and fish-based.
Active electrolocation is practised by two groups of weakly electric fish, the Gymnotiformes (knifefishes) and the Mormyridae (elephantfishes), and by Gymnarchus niloticus, the African knifefish. An electric fish generates an electric field using an electric organ, modified from muscles in its tail. The field is called weak if it is only enough ...
Fish oil is rich in omega-3 fatty acids, which are important for your brain health, memory, heart health, and reproductive system—among other things.
You’ll find choline in eggs, beef, poultry, pork, fish and dairy products. Cruciferous vegetables, soybeans (including tofu), shiitake mushrooms, peanuts, wheat germ, almonds, kidney beans, lima ...
Other names in English include elephantnose fish, long-nosed elephant fish, and Ubangi mormyrid, after the Ubangi River. The Latin name petersii is probably for the German naturalist Wilhelm Peters. The fish uses electrolocation to find prey, and has the largest brain-to-body oxygen use ratio of all known vertebrates (around 0.6). [2]
