On top of that, it's unlocked and very compact. In testing around the San Francisco Bay Area, the MiFi 6620L performed very well, with excellent 4G LTE Internet speed. But all of that comes at a high price. The Jetpack costs $200, or $50 if you're willing to sign up for a two-year contract.
Rays account for about half of all elasmobranch species. Of the 500 or more described ray species, there are over 150 stingray species that are assigned to approximately 20 genera. Freshwater stingrays of the family Potamotrygonidae are assigned to the genera Paratrygon, Plesiotrygon, Heliotrygon and Potamotrygon.
Giant freshwater stingrays are listed as endangered by the International Union for the Conservation of Nature, in part due to Hogan's and Nantarika's work. âThese rays are decreasing rapidly since there is no national law to protect them,â Nantarika says.he giant freshwater stingray has the longest spine of any species of ray, up to 15 inches, and carries powerful venom. The animal uses its spine for defense and it can be lethal, but injuries to people are quite rare. Check out this archive video of Zeb Hogan examining another freshwater stingray.
