In this study, scientists trained port jackson sharks to follow music played at one end of a fish tank for a food reward. The results of the study illustrate a lot about what sharks are capable of.

Invasive rats have been successfully eradicated from Antarctic Island

A successful invasive species eradication program has rid South Georgia island in the Antarctic of rats. The efforts of the Scottish charity, South Georgia Heritage Trust, began in 2010 and just wrapped up after waiting two years after the last application of rodenticide.

In a new study scientists admit there is a lot to learn about mantis shrimp vision systems

In a newly published study on mantis shrimp, scientists admit “We’re nowhere close” to solving the mystery of their vision systems. In a study published yesterday in The Royal Society, scientists tried to get to the bottom of mantis shrimp vision systems once again by investigating gaze stabilization. Biologist Ilse Daly, with the University of Bristol in Britain, was the lead scientist on the study of peacock mantis shrimps. During the research Daly found the orientation of their eyeballs “doesn’t seem to have any bearing on their perception of space”.

Great White Shark tagged off South Carolina last year shows up in Gulf of Mexico

Hilton, the 12-foot 1,326 pound great white shark that was tagged by Ocearch off Hilton Head, South Carolina in March of last year, just showed up in the Gulf of Mexico. However, the resulting path of the “Twitter famous” shark showed him traveling across the Florida panhandle to reach said location.

Scientists believe the relatively small male shark may have moved to the Gulf of Mexico to take advantage of the warmer water and abundant deepwater fish.
