burbot vs bowfin
The giant (or red) snakehead is an aggressive predator that feeds on fish, frogs, aquatic birds, and, in some cases, small mammals. The burbot frequents cool waters of large rivers, and the lower reaches of their tributaries, and lakes -- particularly in northern Wisconsin. The cranial surface of the skull is made up of the nasals, the antorbital, the lacrimal, the parietal, the intertemporal, the post parietal, the supratemporal, the extra scapular, the post temporal, and the opercular. [8][70], Bony fish related to gars in the infraclass Holostei. The small glochidia larvae then hatch and develop in the gill tubes. [5][13] Their undulating dorsal fin propels them silently through the water while stalking their prey. Although bowfin are highly evolved, they are often referred to as "primitive fish" because they have retained some morphological characteristics of their early ancestors. The burbot, like the snakehead, has a long anal fin and pelvic fins actually in front of the pectoral fins, however, the burbot has very fine scales and a conspicuous barbel under the chin.

Like gars, bowfin are bimodal breathers which means they have the capacity to breathe both water and air. [50] They can live ten to twelve years in the wild,[50] and 30 years in captivity. [15], Bowfin are often referred to as "living fossils", or "primitive fish" because they retained some of the primitive characters common to their ancestral predecessors,[16] including a modified (rounded externally) heterocercal caudal fin, a highly vascularized gas bladder lung, vestiges of a spiral valve, and a bony gular plate. Their gills exchange gases in the water allowing them to exploit oxygen for breathing, but they also have a gas bladder that serves to maintain buoyancy, and also allows them to breathe air by means of a small pneumatic duct connected from the foregut to the gas bladder. Adults are uniformly yellow or light brown to black or mottled with dark brown or black on back and sides. in pics i guess, but get them in your hand and they really look nothing alike. [48], Bowfin are stalking, ambush predators that customarily move into the shallows at night to prey on fish, and aquatic invertebrates such as crawfish, mollusks, and aquatic insects. The evolution of the vertebral column allows the bowfin to withstand lateral bending that puts the column under compression without breaking. [12][62], Females vacate the nest after spawning,[32] leaving the male behind to protect the eggs during the eight to ten days of incubation. Another three bones make up the lower jaw the dentary, the angular, and the surangular. [4][53][55], Research from the late 1800s to the 1980s suggests a trend of intentional stockings of non-indigenous fish into ponds, lakes and rivers in the United States. Did I just catch a snakehead? The bowfin prefers warmer, shallower water, and generally much weed growth and cover. Snakehead and bowfin body and fin shapes are very similar. [9] A male often has eggs from more than one female in his nest, and a single female often spawns in several nests. [21][22] Some contrasting differences in bowfin include a black eyespot on their caudal peduncle, a tan and olive coloration, a shorter anal fin, a more rounded head, and an upper jaw that is longer than its lower jaw. [44] They are distinguished from their earlier ancestors by major changes to the jaws, shape of the skull, and tail. These types of tails are common in fish with gas bladders, because the bladder supplies the fish with natural buoyancy. [24], The first fish lacked jaws and used negative pressure to suck their food in through their mouths.

This type of tail gives the body a streamlined shape which allows the bowfin to improve its swimming ability by reducing drag. [32], During spawning season, the fins and underside of male bowfin often change in color to a bright lime green.

[26][27] When performing low-level physical activity, bowfin obtain more than half of their oxygen from breathing air. The paired pectoral and pelvic fins of fish are homologous with the limbs of tetrapods. The tail is rounded. Central New York. [53][57], Bowfin prefer vegetated sloughs, lowland rivers and lakes, swamps, backwater areas, and are occasionally found in brackish water. Often thought of as "trash fish" by anglers seeking more prized game fish, such as walleye or northern pike, bowfin are voracious predators, and they fight hard when you hook them. While a halecostome pattern of neopterygian clades was produced in morphology-based analyses of extant actinopterygians, a different result was produced with fossil taxa which showed a monophyletic Holostei. [64] Bowfin are strong fighters, a prized trait in game fish. During the seven to nine days required for yolk-sac absorption, they attach to vegetation by means of an adhesive organ on their snout, and remain protected by the parent male bowfin. Snakeheads may be confused with our native bowfin (dogfish) or burbot. [67] In Louisiana, bowfin are harvested in the wild, and cultured commercially in hatcheries for their meat and roe. Neural spines and ribs provide additional support and help stabilize unpaired fins. Fossil deposits indicate Amiiformes were once widespread in both freshwater and marine environments with a range that spanned across North and South America, Europe, Asia and Africa. [18][19], Northern snakeheads (Channa argus) are commonly mistaken for bowfin because of similarities in appearance, most noticeably their elongated, cylindrical shape, and long dorsal fin that runs along their backs. [60], Bowfin reach sexually maturity at two to three years of age.

Northern snakeheads are piscivorous fish native to the rivers and estuaries of China, Russia, and Korea. The jaw of a bowfin has several contributions.

[39] Bowfin are the last remaining member of Halecomorphi, a group that includes many extinct species in several families. They can extract oxygen from the water when breathing through their gills, and can also break the water's surface to breathe or gulp air through a small pneumatic duct connected from their foregut to the gas bladder.

[36][37] Regardless of the lack of evidence confirming the bowfin's ability to aestivate, it has been noted that bowfin can survive prolonged conditions of exposure to air because they have the ability to breathe air.
