In biology, the electric organ is an organ that an electric fish uses to create an electric field. Electric organs are derived from modified muscle or in some cases nerve tissue , called electrocytes, and have evolved at least six times among the elasmobranchs and teleosts .
The airport has had several names over its lifetime. At the time of its opening in 1970, it was named the Ke-āhole Airport, after its geographical location, Keāhole Point, itself named after the ʻāhole fish found in the area. [6] [7] In 1993, the airport was renamed Keāhole-Kona International Airport, after the nearby resort town of Kona. [8]
Established in 1973, ʻĀhihi-Kīnaʻu Natural Area Reserve includes a coastal lava field and surrounding waters on the southwest coast of the island of Maui, Hawaii. It consists of 1,238 acres (501 ha) on land and 807 acres (327 ha) of ocean along 3 miles (4.8 km) of Maui's southwestern coastline.
A lava flow that's been steadily getting closer and closer to a town on Hawaii's Big Island could potentially become a much larger threat. Clayton Sandell via ABC: "This came from the Kilauea volcano.
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 ...
The elephantnose fish is a weakly electric fish which generates an electric field with its electric organ, detects small variations in the field with its electroreceptors, and processes the detected signals in the brain to locate nearby objects. [12] Weakly electric fish generate a discharge that is typically less than one volt.
In the video, lava could be seen shooting out of Kilauea’s Halemaʻumaʻu crater and up into the air about 330 feet, or almost as high as the length of a football field.
The main organ is the first electric organ to develop, followed by Sachs' organ and then Hunter's organ. All the electric organs are differentiated by the time the body reaches a length of 23 cm (9.1 in). Electric eels are able to produce electrical discharges when they are as small as 7 cm (2.8 in).
