Among his many specimens was a strange fish with fleshy limbs caught from the Nile River, which he described in 1802 as polypterus, meaning “many fins.” Photo by BioDivLibrary/Flickr Advertisement ...
Unfortunately, fossils can only tell us so much. But, if Iida can take the principles he will develop making a robotic Polypterus and apply them to what we know about Tiktaalik, he could create a ...
Can we examine the teeth of living fish and other vertebrates in detail, repeatedly over time, without harming them?
Polypterus "looks very similar to the ancient fish that eventually evolved into tetrapods. That's why scientists examined this species in order to learn a bit more about its unusual ...
There have been fish and fossils found with leg-like fins, but now scientists have raised such animals themselves. Three researchers raised a fish called Polypterus, also known as Bichir, to learn ...
The overlooked 'nose' of an African fish forces scientists to look at the fossil record with new eyes. Study of African fish helps scientists crack the origin of breathing.
The primitive fish known as bichir (Polypterus senegalus) lives in fresh water lakes and rivers in East Africa. It swims primarily by using its pectoral fins, but when placed on land it uses both ...
Caption. Step-by-step process of taking fish teeth impressions: The researchers took teeth molds from Polypterus fish (about 20 cm long); (A) setting up the materials; (B) carefully sedating the ...
A new view of evolution is being put forward by an Ottawa biologist, thanks to an African fish that can leave the water and crawl on land. The little Polypterus fish isn’t pretty, but it has a ...
A polypterus senegalus or “Walking Fish” walks by using its fins and body for support. Scientists have studied the effect of a lifetime of walking on a certain type of fish.
This fish has been separated from other fish species for about 360 million years. Due to this long period of evolutionary isolation, Polypterus still has many primitive characteristics that provide ...
