Alien Parasite !!

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

Please note that image critiquing is a matter of give and take: if you post images for critique, and you then expect to receive criticism, then it is also reasonable, fair and appropriate that, in return, you post your critique of the images of other members here as a matter of courtesy. So please do offer your critique of the images of others; your opinion is important, and will help everyone here enjoy their visit to far greater extent.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

Frogs may be parasitised by a genus of flies - the Batrachomyia (Diptera:Chloropidae). The fly larvae reside in the lymph spaces beneath the skin on the backs of frogs where they ingest the blood of the host frog.

This is a sub-adult Pseudophryne coriacea which we found during our current survey at Tamborine - the first photo shows the fly maggot clearly visible as a large bump under the skin on the dorsal surface of the frogs left side:

This shot shows the posterior spiracles protruding through a small hole next to the frogs eye/shoulder. This maggot when it is ready to pupate, will tear a hole through the frogs skin through which it will exit the body and drop into the soil where it will pupate before beginning the cycle all over again. According to literature, the majority of frogs actually survive this experience - those that die may die due to other causes, an overinfestation of the parasite (there have been records of up to 5 maggots in a single frog), or due to infection of the exit wound. However small frogs may suffer significant tissue damage when the maggot exits :(

Pretty interesting huh ?? :)

Great shots, Rel, and an interesting read. I guess some animals will do anything to pass on their genes.

Poor frog! Wonder if they can feel it...


But nice pics, too much detail (not that it's a bad thing when it comes to photos! ;) )
