caption_attribution_description: Preserved specimen of chalumnae (Also known as Coelacanth [1]) in the Natural History Museum, Vienna, Austria. Believed to have been extinct for 70 million years, this specimen was caught the 18 October of 1974, next to Salimani/Selimani (Grande Comore, Comoros Islands) 11°48′40.7″S 43°16′3.3″E&#xfeff; / &#xfeff;11.811306°S 43.267583°E Length: 170 cm - Weight: 60 kg Obtained by stiching 3 HiRes images and removing the background with image post-processing.
context_page_description: Fish vary greatly in size. The whale shark and basking shark exceed all other fish by a considerable margin in weight and length. Fish are a paraphyletic group that describes aquatic vertebrates while excluding tetrapods, and the bony fish that often represent the group are more closely related to cetaceans such as whales, than to the cartilaginous fish such as sharks and rays. As such, cross group comparisons on this page only serve a colloquial purpose.
context_section_description: The largest living lobe-finned fish is the coelacanth. The average weight of the living West Indian Ocean coelacanth, (Latimeria chalumnae), is 80 kg (180 lb), and they can reach up to 2 m (6.6 ft) in length. Specimens can weigh up to 110 kg (240 lb). The largest lobe-finned fish of all time was Rhizodus at up to 7 m (23 ft).
  Lungfish (Dipnoi)
  The largest lungfish, the African lungfish (Protopterus aethiopicus), is smooth, elongated, and cylindrical with deeply embedded scales. The tail is very long and tapers at the end. They can reach a length of up to 2 m (6.6 ft) and may weigh as much as 50 kg (110 lb). The pectoral and pelvic fins are also very long and thin, almost spaghetti-like.
