They Display Potentially Habits of Lethal Mating Towards Otters and Other Animals

Concealed beneath those button noses and fluffy fur lies a creature with some really frightening mating habits. During mating, male otters hold onto the female and bite her nose, sometimes even hard enough that blood starts gushing out and causes deep wounds.

The act sometimes involves the male grabbing the female's head underwater and as the two turns and wriggle under the surface. Most females drown in this process.

Otters Will Resort to Acute Behaviors Just to Get Some Food

Otters have big appetites to account for the great conditions they face. They are the smallest marine mammals on earth, but they consume about a quarter of their own body mass daily and most of the energy is used just to keep their little otter bodies warm. Life becomes very difficult for female otters when nurturing young pups.

Otters Have Attacked Humans and Other Animals Similarly

Although experts say otter attacks on humans are infrequent, there are a number of recorded occurrences. Since 1875 a study discovered that there have been 39 cases of anecdote attacks on humans announced in newspapers, and four recorded in scientific.

Sea Otters Can Serve as Reservoirs For Influenza Viruses

In 2014, the US Geological Survey (USGS) released a study of northern sea otters living close to Washington who were discovered to have possessed H1N1 virus (swine flu) throughout a large number of their population.

The otters were examined in 2011 and none of the population showed any symptoms of the virus, but antibodies for the virus were discovered within 70 percent of 51 otters sampled.

Researchers were not certain how the otters succeeded in getting the virus, but researchers theorize it may have dispersed to otter populations during the time of the H1N1 outbreak in 2009.
