For several years something mysterious has been plaguing sea otter1 populations off the coast of California.
The animal may have seizure2s, it may shake, it may act like it's weak, uh, it may not seem like it's very aware of its surroundings, and it may seem to have problems, uh, bringing food to its mouth as those kinds of things that tips off it. Something isn't quite right with this animal.
These symptoms and other research data point in part to an unlikely culprit, a parasite4 that causes toxoplasmosis.
The first big surprise for us was how common the infection really was. Uh, what we found was that about 4 out of every 10 live otters5 that we tested actually had antibodies to the parasite. Good boy.
And even more surprising was a link to human population centers where the parasite is transported by fresh water runoff. A university of California study confirmed that otters sampled near major streams and rivers were almost 3 times more likely to test positive for the parasite than those living away from fresh water. Other factors could also be responsible, everything from other parasites6 and diseases to pollution and pesticides7.
The bottom line right now is it remains8 an open question.
Sea otters eat about 25 percent of their body weight in shellfish and other invertebrates9 everyday. Since people eat some of the same seafoods10, this poses the question of how humans might be affected11, sending a warning to a fishing industry that the state heavily depends on.
Hey, Morgan, hey, Rick, hi buddy12.
It's also important to remember that this is not just about saving sea otters, that's important, but it's about saving marine13 ecosystems14 because the organisms that we are seeing have significant implications for human health that has concordance for the people of California, the people of the world that want to enjoy and utilize16 the Pacific coast.
And that is what is raising the stakes.
What you think, ah?
Making the effort to save the sea otters, a California state priority.
seizure: A sudden attack, spasm17, or convulsion, as in epilepsy or another disorder18. 发作突然的
tip off: An indication of an otherwise unknown fact or probability 表明;暗示
toxoplasmosis: [医]弓形体病, 弓浆虫病
bottom line: The main or essential point 要点或关键之处
concordance: Agreement; concord15. 协议;和谐
