And later when I was interested in learning about fungi, I didn't have anybody to help me with it. Someone suggested iNaturalist to me, and it's on your cell phone.

Essentially people can take a photo of anything living, plants, animal, fungus, slime mold, put it on the website and other people identify it.

本质上，人们可以给任何有生命的东西拍照，比如植物、动物、真菌、黏菌，然后把照片上传到网站上，然后由其他人来识别。

The app compares the image with those already in the database to begin the identification process. But ultimately, human experts weigh in.

该应用将图像与数据库中已有的图像进行比较以启动识别过程，但最终仍需由人类专家进行判断。

每年的这个时候，我特别想找到蝾螈。我一直很喜欢观察哺乳动物，它们是我最喜欢的动物之一，当然还有鸟类。我已经有近55000次观察记录了，这可不少。

iNaturalist has observations from every country in the world. Right now, I believe we have over 26 million observations and about 700,000 active users.

iNaturalist拥有来自世界各国的观察记录。目前，我认为我们有超过2600万条观测数据和约70万活跃用户。

the type of giant sunfish whose normal habitat is thousands of miles to the south, an indication perhaps of a rapidly changing world.
