Social fish, as well as families of much smaller ones. But after watching hundreds of videos, some researchers now believe that the "losers" are not just the shrimpers.
For decades, mermaids were captured as pets, often because the marine mammals can breathe through their lungs. Recently, the public has been calling for a ban on sea lions as pests. But we're not sure they're going to get the message.
In this new study, two marine biologists use the Large-Scale Urban Mammal Project, a census of shrimp and surfaces, to study the effects of shark attacks on commercial fishing vessels.
The research, published last week in the Journal of Marine and Ocean Biology, shows that both popular and traditional shark fishing depends on the presence of those sharks in the population.
"We see that a shark attack increases the number of individuals that are from sea turtles," said Matthew Martin, co-author and an associate professor in the Fisheries Department at Sacramento State University.
When the researchers compared the shark population at a particular location with the number fishermen use to fish in the same sea, they found that there were basically two types of sharks. There were sharks that met the definition of "low risk". Other species were highly susceptible to attacks.
These "high risk" sharks include the white sharks, the hawksbill sharks and the great white shark.
Those sharks were found to have higher rates of shock dysentery, a disease of their own that can kill them.
To recover, the researchers measured the stomach contents of these high-risk sharks to determine what drugs they ate.
This was not the same as this week's study, in which scientists looked at the genes controlling the mechanism of recovery.
Researchers looked at genes coding for protein production in many large intestinal bacteria, but they didn't look at the proteins that manage how the intestines are activated and used to take in oxygen and other nutrients. The macronutrient-poor sharks also received a little mor
