      1. Hey Zach- I am a stream ecologist and professor who is writing a field guide book on rivers and streams. Shots like these are exactly what I am after for the chapter on fish. If you are interested in seeing your work in print, let me know. Posted one year ago
        1. Hey utzryan! I'd love to collaborate! I've been really busy with grad school, but have a boatload of images i'll be uploading as soon as I get a chance. I've been really busy with the camera since I last uploaded images, so there is quite a bit to come. Feel free to reach out via email (alleyz@uwa.edu) if you'd like to discuss further about what species you're after! Posted one year ago

  4. From today's Facebook post:

    Greenside darters (Etheostoma blennioides) live in the rivers and lakes of eastern North America where they tend to prefer the riffles of moderate to fast-moving water. They reach sexual maturity at one to two years of age, and grow no larger than about 127 mm (5 in) in length. Greenside darters have a reduced swim bladder, which makes it difficult for them to float in water. So, they spend most of their time on the bottom of their habitat.

    They have numerous predators, but the darters have a strategy in which they freeze when a predator approaches. They can remain frozen for awhile, blending in with their surroundings and avoiding predation. Aside from serving as a food source, greenside darters have another important role in their ecosystem: they play an important part in the lifecycle of several freshwater mussels. For example, the critically endangered birdwing pearlymussel (Lemiox rimosus) uses the greenside darter as its host. The mussel has a snail-mimicking lure to attract the darters, who happen to love eating snails. Once the fish bites down on the lure, the mussel releases a load of tiny larvae, which attach to the gills of the fish. The mussel larvae can’t swim and will die without a host fish. They remain attached until they have developed a shell, at which point they let go, bury themselves in the riffles, and live as long as 50 years! {Spotted in Ohio, USA by JungleDragon user, Zach Alley} #JungleDragon #GreensideDarter #Etheostomablennioides
