Sharks are fairly eclectic eaters. They’re going to go for prey starting from fish and invertebrates to sea mammals and turtles. A shark could actually have a chomp on the odd surfer. If they’ll catch it, or scavenge it, and it is made from meat, sharks will usually eat it.
A brand new research figuring out the contents of the bellies of child tiger sharks ( Galeocerdo cuvier) utilizing DNA evaluation has discovered a dietary part nobody anticipated, although: land-primarily based songbirds.
Sure, like those you see in your yard, equivalent to doves, sparrows, and meadowlarks.
“Tiger sharks will see a simple meal and snatch it up, however I used to be shocked to study that the sharks had been consuming songbirds – I assumed that they’d be seabirds,” said biologist Kevin Feldheim of the Chicago Field Museum.
“It was one of many coolest tasks I have been related to utilizing DNA to inform a narrative.”
It began after a small tiger shark off the Mississippi-Alabama coast coughed up some land-chook feathers – from a brown thrasher (Toxostoma rufum) throughout a shark inhabitants monitoring survey in 2010.
This was a shock, so a group of researchers from Mississippi State College determined to analyze additional. Simply how frequent was it? The best means to determine what an animal likes to eat is to take a look at what’s being digested in its stomach, so that is what the group did.
