The gilled lungfish, Protopterus amphibius is a species of lungfish found in East Africa. [30] [31] It generally reaches only 44 centimetres (17 inches) long, making it the smallest extant lungfish in the world. [32] This lungfish is uniform blue, or slate grey in colour. It has small or inconspicuous black spots, and a pale grey belly. [33]
She was joined by another lungfish, named after Herb Caen, in 1952 [7] [8] or 1958. [2] She was given the name Methuselah by Steinhart Aquarium director John McCosker in 1988 after spending 50 years at the aquarium. [9] Due to damage incurred in the 1989 Loma Prieta earthquake, the original Steinhart Aquarium was torn down in 2005.
Australian lungfish are commonly found in deep pools of 3–10 m (9.8–32.8 ft) depth [14] and live in small groups under submerged logs, in dense banks of aquatic macrophytes, or in underwater caves formed by soil being washed away under tree roots on river banks. The lungfish is tolerant of cold, but prefers waters with temperatures in the ...
Scientists from the California Academy of Sciences now estimate that Methuselah, the aquarium's beloved Australian lungfish, is 92 years old. The aquarium previously estimated Methuselah's age was 84.
Furthermore, the African lungfish is commonly used for food consumption in many African regions. In Ugandan fish markets, African lungfish can frequently be found. According to some studies, Uganda caught between 15,000 and 22,000 tons of lungfish from 1976 to 1985, but this number decreased from 1985 to 1989.
