On his right eye, our left, there is a little mark which looks very much like a mite! I have posted a WS to show it in more detail. Does anyone know what it is for sure?

This is the same frog that I posted a few days ago.

I hope you like it!

Common frog, grass frog
Rana temporaria
The common frog can breathe through its skin. This enables it to hibernate for several months beneath piles of mud and decaying leaves underwater.



Subspecies
Three: R.t.temporaria, R.t.honnorati (colonises an area at the foot of the Alps) and R.t. parvipalmata (north west Spain and the Pyrenees).



Life span
In the wild, the common frog can live for up to 8 years.



Statistics
Body length: Can be anywhere between 6 and 10cm, although they are usually 7.5 to 8cm long, with an average weight of 22.7 grams. Females are usually slightly larger than males.



Physical description
Common frogs have a robust body and relatively short hind limbs with webbed toes. Males tend to be slightly smaller and darker than females, and can also be distinguished by the dark bluish-black nuptial pads (swellings) on their first fingers. These pads become more pronounced during the breeding season, helping males to grip on to females during mating. The common frogs’ smooth skin varies in colour from grey, olive green and yellow to various shades of brown and is covered with irregular dark blotches. Common frogs have a dark ‘mask’ enclosing their eyes and eardrums, and often have barred markings on their limbs and flanks. Their undersides are white or yellow, sometimes orange in females, and are often covered with brown or orange speckles. Completely red or black individuals are occasionally found in Scotland, and some individuals may turn blue during the breeding season. Albino common frogs have been found with yellow skin and red eyes. Common frogs also have the ability to lighten or darken their skin to match their environment. Common frogs have brown eyes with black horizontal pupils, and transparent inner eyelids that protect their eyes while they are underwater.



Distribution
This species is one of the most widespread and common species of brown frog (member of the Ranidae family) in Europe. They are widespread and native to mainland Britain and have been introduced to Ireland, where their distribution is patchy. They have also been introduced to the Isle of Lewis, Shetland and Orkney Islands. Common frogs are also found in Asia, and eastward to Japan.



Habitat
Common frogs are largely terrestrial outside the breeding season, and can be found in meadows, gardens and woodland. They breed in puddles, ponds, lakes and canals, preferring areas of shallow water.



Diet
Common frogs do not feed at all throughout the breeding season, but when they are active they will feed on any moving invertebrates of a suitable size, such as insects, snails, slugs and worms, which they catch with their long, sticky tongues. Adult frogs feed entirely on land, whereas younger frogs will also feed in the water. Tadpoles are herbivorous and feed on algae but become carnivores when they mature into adult frogs.



Behaviour
Although common frogs are active both day and night, they tend to be more active at night. During the winter they hibernate in compost heaps, under stones and logs, or underwater beneath piles of mud and decaying leaves.



Reproduction
Common frogs become sexually mature at around three years of age. During February and March they begin to emerge from hibernation and make their way to the breeding grounds. Common frogs have been seen to return annually to the sites where they originally developed from spawn into adult frogs. The males arrive first and attempt to attract a mate by producing a low purring croak. A successful male will wrap his forelimbs around the female in a mating embrace known as 'amplexus'. Each female lays 1000-4000 eggs at a time, which are fertilised by the male as they are released. Frogs can spawn as early as December and as late as April, depending on how warm the weather is. They prefer to lay their eggs in shallow, still water. Frogspawn is surrounded with a clear jelly-like substance, which swells up in the water to protect the fragile embryos. The spawn floats to the surface in large round clumps so that the sun can warm the eggs. After 30 to 40 days, tadpoles begin to emerge from the jelly-like spawn. The tadpoles feed on the spawn for the first few days until they begin to eat algae. Tadpoles change into frogs through a process called ‘metamorphosis’, which takes between 12 and 14 weeks. Both spawn and tadpoles are extremely vulnerable, and many get eaten by predators such as fish, birds and grass snakes. On average, only 5 out of every 2000 eggs will survive to become adult frogs. When tadpoles hatch they have gills that allow them to breathe underwater. After 9 weeks they have lost their gills and developed lungs, and therefore must swim to the surface to breathe. As they grow, tadpoles begin to feed on insects as well as plants. Hind legs develop between 6 and 9 weeks, and front legs are fully developed after about 11 weeks. The tail begins to be absorbed by the developing tadpole, and by 12 weeks it has practically disappeared, leaving a tiny froglet. At this stage the tadpoles are less dependent on water and will hide in long grass in and around the pond.



Conservation status
The common frog is protected under the Wildlife and Countryside act 1981. This species is not listed by the IUCN. Populations can be threatened in areas where breeding ponds are disturbed or polluted.



Voice
Males emit a low purring croak during the breeding season, but this can only be heard up to 50 metres away because common frogs do not have any vocal sacs.



Notes
Common frogs can breathe through their skin as well as their lungs. Their eyes and nostrils are on top of their heads so they can see and breathe even when most of their body is underwater.

Thanks!

Hi Joe,
A nice capture of this frog. Yes it looks like a mite might be some parasite living in the eyes of the frog don't know. Anyway a very good capture with good details and composition. Thanks a lot for sharing.

Hi Joe!

This is an outstanding picture, as we are used to see them from you. The little insect - can't help with the ID - adds to the value of the picture. The frog looks so cute and seems to look at us with bonhomie. The details and the lighting are superb!

Kind regards

Markus

Hi Joe
Very ineteresting presentation. Your photo is very good Great DOF and POV. Fantastic eye contact. I like also WS photo.

As for small creature it is not a mite It is an insect - member of Collembola Maybe some kind of Podura sp.

Best wishes
Krzysztof

Hello Joe,
The capture of the face on view of this Common Frog is great, especially with the duckweed strewn round its mouth, but of course what makes this remarkable is the tiny mite on the eye, spotted after taking the shot, I presume!
Excellent use of flash and sharp focusing has led to this superb image and I thank you for sharing it!
Ivan

Hi Joe,
Lovely face to face shot. Sharp and well seen image. The insect is too small to bother by this huge frog.
JC

Hello Joe,
An amazing portrait of your little friend!
I like the symmetry in the composition, where the two big eyes are natural eye-catchers...
Super sharp details and the DOF is effective in isolating the main element!

Hello Joe, my beloved friend Owlman!
I will miss your captures and you during the trips! Another lovely capture of a frog! TFS.
Cheers,

(Stockers doesn't look good for me on Sunday, i am moving house this w/e unfortunately...and the weather doesn't look that great either)

Hello Joe

Hi joe perfect shot very close view perfect sharpness good focus exzellent I will add to my favorites thanks a lot for sharing
Best regards Toba

that's pretty cool...I can see the mite...or the speck but you were there..an interesting take. Yesterday I saw some sparrows landing on a goose at the lake...and then we have mollusks and whales...animals helping animals..sounds like a movie!
Bob

Wow!
Fantastic shot!
Even without the insect it is perfect. I like this kind of point of view. Sharpness and colours nice as well.
Did you notice the mite on the eye of the frog when you were taking the picture or it appeared later?

Hi Joe,

Oh my goodness - that is a little buggy of some kind in his eye. Superb close-up. I thought it was just a speck. Another amazing macro showing off those wonderful eyes.

Hi Joe

Lovely shot of your pond lodger, nicely composed with a excellent frontal POV, love the pose too, lovely sharp detail and the mite in the eye is really cool, I like the way you have focussed on the Frogs head letting the rest blend into the OOF BG, good use of light too.

Hi Joe. Very good work with the Sigma to see this on the eye. great detail and colours. I like the pose with the green weed around the mouth. you have captured the markings so well TFs.
Nick..
See you Sunday fingers crossed for the weather

Hello Joe, Excellent sharp shot even the mite looks well formed! I like this lens seems very sharp indeed. Good DOF and nice light. See you Sunday rgds Necip.

Again a beautiful frontal portrait of this fine frog specimen Joe, with an evident emphasis on the eyes, but sorry my friend, I can not help you with that mite-like minute organism, hope somebody does.

Hello Joe

Just marking the post for now

Rob

Wow Joe, great portrait off splendid frog with amazing reflection on eye!, excellent composition with splendid focus, very well done, have a great week end, ciao Silvio

Hello Joe.
This shot has a great composition, nice exposure and details. The mite is a perfect bonus. It is very interesting to discover this little creatures.
It is not the first time I find "polizon subjects" in my macros when postprocessing, and I love it :)
I posted something like this a long time ago, HERE.
Thanks and regards, Felipe.

Hello Joe,
You were really observant noticing this little mite on the eye! Quite amazing! It's sure a bonus but the image without it is brilliant too. Excellent sharpness and fine natural colours. The green Duckweed adds a lot to this shot too. Very well done!!
TFS and cheers, Ulla

Hi Joe,
I like the frontal POV and the small green vegetation that frames that beautiful face ;)
Good detail with the flash helping to reveal the mite on it's eye..
Here's where I say good "eye" for the shot ;-}}
Well done,
Howard

I just love love love frog photos. Maybe it's the fairy tale that it reminds me of...not sure but there's something almost magical about them.
Wonderful shot - great angle, good point of view...just great shot! :)

Hi Joe

It does look like a little insect - very well spotted. I love the POV here and the direct eye to eye stare. Nice DOF and good sharp details.

Enjoy your day out tomorrow and do forget to wear your thermals - winter is coming back!

Hi Joe

I managed to find some spare time this nice Sunday afternoon and as usual i checked you gallery again...and you know me and frog photos ;)

This is a superb close-up and a very interesting shot as well.
No clue of what exactly that mite is bit there are many kinds of parasites for frogs. However, it might also only be a small Aphid from the leaves around the frog...either way, it's a terrific capture :)
Excellent sharpness and very good DOF, all well illuminated by a great flash work!

Bravo, TFS and take care, mate!
Horia

Hi Joey

Great shot. I love the detail that is shown, including the insect... great DOF and focus.
