Nile Crocodiles Have Been Found in Florida

Four Nile crocodiles have been found in Florida by scientists from the University of Florida. Between 2002 and 2004, the researchers have studied populations of crocodiles in the state. Previously, using DNA analysis, they found three Nile crocs: one was a foot long hatchling sitting on a porch in Miami. Another was found on the property of a private zoo in Homestead, and a third, also in Homestead, a 10-pound (4.5 kg) female, was captured in a public park.

The shark that glowing in the dark has been announced as a New Species: the “Ninja lanternshark”

In 2010, during an expedition of the Spanish research ship Miguel Oliver, the researchers from the Smithsonian Tropical Research Institute discovered a new type of shark in the Pacific Ocean near Central America, off the coasts of Nicaragua, Panama and Costa Rica. The shark was glowing in the dark. Now it is officially a new kind of shark: its scientific name is Etmopterus benchleyi (it features a tribute to the famous 1974 novel “Jaws” author Peter Benchley), but since it is pure black, it is called “Ninja lanternshark”.
