1 The training course is five weeks. 2  During the first two weeks, students are in the classroom. 3  During the second three weeks, students complete a clinical externship at various Intermountain Healthcare hospitals.
But surprisingly, we still donât know how many species live by the shore: estimates vary widely, from 178,000 species to more than 10 million. NaGISA scientists pulled on their boots and waded and dived in coastal waters around the world to estimate the number of species on our coasts more precisely.
About 1.8 million have been given scientific names. Thousands more are added to the list every year. Over the last half century, scientific estimates of the total number of living species have ranged from 3 to 100 million. The most recent methodical survey indicates that it is likely to be close to 9 million, with 6.5 million of them living on the land and 2.2 million in the oceans.
