whitetip (Carchathinus longimanus), porbeagle (Lamna
fue descrita de Bolivia, pero la localidad tipo queda por confirmar, ya que el ejemplar tipo se encuentra perdido, y se desconoce la existencia de ejemplares, con datos fiables, recolectados ultimamente de Bolivia.
et al in Mom's Taxi (2003), look at social and class distinctions between people living in suburbs-and-townships, as well as suburbs-and-Cape-Flats, whilst Fritz's Taking the Rap (2004), confronts the issue of poor whites and racial stereotyping.
For example young porbeagles (Lamna
nasus) are sometimes mistaken for shortfin makos because their teeth lack cusplets, and young white sharks are mistaken for porbeagles because their teeth partially lack serrated edges and show cusplets.
Moreover, a shark of the genus Lamna
is present in the Alabama fauna as it is in the Clayton Formation fauna.
The porbeagle (Lamna
nasus), a pelagic shark in the family Lamnidae, inhabits the cold temperate waters of the North and South Atlantic, South Pacific, and southern Indian Oceans as well as the subantarctic region of the Southern Ocean (Castro, 2011).
Es una de las cinco especies de la familia Lamnidae que comprende a los generos Isurus, Carcharodon y Lamna
(Compagno, 1984; Nelson, 2006).
With the exceptions of Porbeagle, Lamna
nasus, that had been targeted in the early 1960's off New England (Campana et al., 2001), and Dusky Sharks, Carcharhinus obscurus, that had been taken incidentally in Japanese tuna fisheries in the Gulf of Mexico in the same decade, the shark stocks in the southeastern U.S.
In the eastern North Pacific, the salmon shark (Lamna
ditropis) is commonly misidentified as a white shark, and while at least one specimen has been shown to occur in Hawaii , it exhibits a strong tropical submergence and this has not been directly observed or captured.
In the Submeseta Allomember, there is a dramatic diminution of diversity of those selachians that dominated below, there are no teleost taxa characteristic of warm water (e.g., Labridae, Oplegnathidae, Xiphiorhynchidae), sharks dramatically decreases in diversity and quantity (a few Pristiophorus and odontaspidid teeth) and begin to predominate some sharks (Lamna
) and teleosts with species characteristic of colder waters (e.g., gadiforms of the informal genus "Mesetaichthys") are recorded.
