What is a bowfin (dogfish)?
The bowfin, commonly called dogfish in the Midwest, is truly a one of a kind fish. It is scientifically known as Amia calva, which is derived from the Greek, Amia meaning fish and calva meaning smooth.

They can also survive out of water for a considerable time. This primitive fish was around when dinosaurs roamed the earth. It is also known as a dogfish. The bowfin is a tubular, olive-green fish with a scaleless head and two barbels on its face. Its dorsal fin stretches most of the length of its back.
Why do bowfin fish have tails?
This type of tail gives the body a streamlined shape which allows the bowfin to improve its swimming ability by reducing drag. These types of tails are common in fish with gas bladders, because the bladder supplies the fish with natural buoyancy.

Can bowfin bite you?
Unlike most fish, bowfin use their swim bladder like a lung to grab oxygen from the air, when oxygen levels become low in the stagnant, muddy, and vegetation rich nonmoving backwaters. Another unique aspect of these fish is that when they first strike your bait it is a subtle bite, followed by a normal fight.

What gene is expressed in the pectoral fin?
While the bowfin pectoral fins did express many of the expected appendage growth genes, some of the most critical of these genes were in fact entirely absent. One such gene called fibroblast growth factor 8 (Fgf8) is turned on at the far tip of developing fins and limbs and is required for the outgrowth of these appendages. When Fgf8 is lost appendage outgrowth is impaired, and if extra Fgf8 is applied to an embryo, it can cause a new limb to form. “Every other fin and limb we know of expresses Fgf8 during development,” Hawkins said. “Discovering that bowfin fins don’t express Fgf8 is like finding a car that runs without a gas pedal. That the bowfin has accomplished this rewiring indicates unexpected flexibility in the fin development program. With the genome in hand, we can now unlock how this flexibility evolved.”
Why is Hawkins focused on the pectoral fin of the bowfin?
Hawkins focused on the pectoral fin of the bowfin because of its ancestral configuration of the skeleton. The bowfin retains the metapterygium, which is a portion of the fin skeleton that is homologous to the limb bones of tetrapods. Model organisms such as the widely used zebrafish and medaka have lost the metapterygium, which makes comparisons between the fin and the limb difficult. By studying the bowfin fin, scientists can use knowledge of bowfin development as a steppingstone to bridge teleost fin development to tetrapod limb development and help explain the evolution of the fin-to-limb transition.
What gene is found in the fins of bowfins?
While some genes like Fgf8 were mysteriously absent from the bowfin fin, other genes were unexpectedly activated in the fins. The HoxD14 gene is expressed in the fins of fishes from the deeper branches of the fish family tree, such as paddlefish, but this gene was lost in more recent branches including the teleosts. When the authors found this gene in the bowfin genome data, they thought it must not be expressed because the DNA sequence did not encode a functional protein. Surprisingly, Hawkins and colleagues found that bowfin fins made HoxD14 gene transcripts at high levels, even though it did not code for a protein. “The fact that the HoxD14 gene can no longer make a protein, but it still transcribed into mRNA at such high levels suggests that there might be another function that we do not yet understand. We might be seeing a new level of Hox gene regulation at play in the bowfin,” said Hawkins.
Why is the Bowfin important?
Due to this special position in the fish family tree, the bowfin can help scientists understand how aspects of modern fishes evolved from their ancient antecedents. By examining the bowfin genome, scientists can investigate the genetic basis of the unique set of old and new features of the bowfin. They can also use this genomic information as a framework to better understand the origin of the teleosts, which have duplicated and extensively modified their genomes since separating from the bowfin lineage and emerging as the dominant lineage in most aquatic habitats.
What does FGF8 and HoxD14 show?
Taken together the Fgf8 and HoxD14 results indicate that genetic programs, even those that guide the formation of important structures such as fins and limbs, are not as invariable as previously thought . “By studying more species, we learn which rules are hard and fast and which ones evolution can tinker with. Our study shows the importance of sampling a broader swath of natural diversity. We might just find important exceptions to established rules,” said Hawkins.
Where do bowfin fish live?
The bowfin is a bony fish endemic to eastern North America and is the sole surviving member of a once large lineage of many species that are now known only from fossils. Scientists have long been fascinated with the bowfin because it bears a combination of ancestral features, such as lung-like air breathing and a robust fin skeleton, and derived features like simplified scales and a reduced tail. The bowfin also occupies a key position in the fish family tree, where it sits between the teleosts, a large and diverse group that arose recently, and more ancient branches that include sturgeons, paddlefish, and bichirs.
