Hyperoglyphe Perciformis
''Hyperoglyphe perciformis'', the barrelfish is a primarily Pelagic_fish#Bathypelagic_fish, bathypelagic species of ray-finned fish belonging to the family Centrolophidae. The barrelfish is found in the Northern Atlantic Ocean. Despite being in the medusafish family, the barrelfish does not associate with jellyfish or other medusae. It is considered a deep-water gamefish. Description The barrelfish primarily has a brown to black coloration on their back, fading to gray on the sides of the body. The dorsal fin normally has 8 spines, and 20 to 22 soft rays. Barrelfish are relatively deep bodied, and have large eyes adapted for sight in the bathypelagic zone. Younger barrelfish have smaller eyes compared to adults, as they do not inhabit deeper water until they grow larger. The young barrelfish found in the upper water columns are often no larger than 1 ft, but adults can grow up to 3 ft in length and weigh up to 27 lbs. Distribution The native range of barrelfish includes the subtr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelagic Fish
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that do live on or near the bottom, and reef fish that are associated with coral reefs. The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of . About 98% of the total water volume is below , and 75% is below . Moyle and Cech, p. 585 Marine pelagic fish can be divided into coastal (inshore) fish and oceanic (offshore) fish. Coastal pelagic fish inhabit the relatively shallow and sunlit waters above the continental shelf, while oceanic pelagic fish inhabit the vast and deep waters beyond the continental shelf (even though they also may swim inshore). Pelagic fish range in size from small coastal forage fish, such as herrings and sardines, to large apex pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
