blacknose shark
carcharhinus acronotus latin

The blacknose shark has never been implicated in an attack on humans.

The blacknose shark has a slender, streamlined body with a long, rounded snout and large eyes.

Female blacknose sharks grow more slowly, attain a larger ultimate size, and have a longer lifespan than males.

By contrast, blacknose shark stocks off northern Brazil appear to be stable, while no fishery data are available from the Caribbean.

Blacknose sharks demonstrate a high degree of philopatry: both juveniles and adults have been documented returning to the same local area year after year.

Blacknose sharks feed primarily on small bony fishes and cephalopods, and in turn fall prey to larger sharks.

Carcharhinus acronotus (Blacknose shark)

For the purposes of commercial quotas and bag limits, the blacknose shark is classified within the "small coastal shark" (SCS) complex.

However, this interpretation has not been borne out by studies of mitochondrial and ribosomal DNA, which instead suggest affinity with the blacknose shark (C. acronotus).

Gavin Naylor's 1992 allozyme analysis found that the finetooth shark is the second-most basal member of the genus next to the blacknose shark (C. acronotus).

Large numbers of blacknose sharks are also caught incidentally by shrimp trawlers, which may pose a greater threat to its population, as many of the sharks taken are immature.

The blacknose shark (Carcharhinus acronotus) is a species of requiem shark, family Carcharhinidae, common in the tropical and subtropical waters of the western Atlantic Ocean.

Blacknose sharks are preyed upon by larger sharks, and captives have been observed to perform an apparent threat display towards encroaching divers or newly introduced members of their species.

The whitenose shark (Nasolamia velox), found along the tropical western coast of the Americas, may be descended from blacknose sharks that experienced the teratogenic effects of incipient cyclopia.

In 2009, the U.S. National Oceanic and Atmospheric Administration announced the populations of the blacknose shark off the United States are being overfished, and proposed new conservation measures.

In 2009, the NOAA proposed instituting a separate quota for blacknose sharks of 6,065 sharks per year, and a ban on using gillnets to catch sharks in the Atlantic.

As in other requiem sharks, the blacknose shark is viviparous: after the developing embryos exhaust their supply of yolk, the empty yolk sac develops into a placental connection through which the mother provides nourishment.

The earliest name was once thought to be Auguste Duméril's 1865 Carcharias remotus, until it was found that the type specimen associated with that name is actually a blacknose shark (C. acronotus).

A small, fast-swimming predator, the blacknose shark feeds primarily on small, bony fishes, including pinfish, croakers, porgies, anchovies, spiny boxfish, and porcupinefish, as well as on octopus and other cephalopods.

The Cuban naturalist Felipe Poey published the first description of the blacknose shark in 1860 as Squalus acronotus, in his Memorias sobre la historia natural de la Isla de Cuba.

Off the United States, the fishing of the blacknose shark is regulated by the U.S. National Marine Fisheries Service 1993 Fisheries Management Plan (FMP) for Atlantic and Gulf of Mexico sharks.

The blacknose shark inhabits the continental and insular shelves off the eastern coast of the Americas, as far north as North Carolina and as far south as southern Brazil, including the Bahamas, the Gulf of Mexico, and the Caribbean Sea.

Blacknose sharks in the South Atlantic Bight (off the Atlantic coast of the southern United States) migrate northward in the summer and southward (or possibly offshore) in the winter; a similar migration occurs for sharks in the Gulf of Mexico.
