Valkea River Frog

This article was written for Summer Camp 2025. Therefore it is unpolished and lacking formatting and information. Feel free to comment with any questions or requests for clarification.
  The Valkea river frog, also known as the milknap frog, is native to Zenra's vast rainforest. Whilst the majority of the species lives along the often flooded banks of the Valkea river, others live in damp pockets of the forest further away from the river, their ancestors carried there long ago by particularly enthusiastic floods.   Their breeding cycle is linked to the river and the floods. Every year, there are a few short months when the rains stop and the river retreats behind its banks; when the rains come again, the breeding season begins. Female river frogs are able to lay up to four thousand eggs over the course of a few months. Those that live further from the river breed less often, their cycles dictated by the size of the pools they call home.   For the first months of the rainy season, it is not uncommon to see frothy masses of frogspawn clinging to the submerged trunks of trees. The Imthic merfolk often harvest the eggs for food purposes, though they never take more than half of the spawn from each cluster.   After a few weeks, the eggs hatch into jewel-toned, deep blue tadpoles. The tadpoles feast on the algae that is able to grow in the comparatively still water of the flooded forest, as well as decaying leaf litter. Many of them are eaten by fish and birds, despite their deep colour providing natural camouflage. After about a month, the tadpoles begin to grow legs, starting their metamorphosis into adults. Their hind legs grow first, followed by their forelegs, and finally their tail shrinks itself into nonexistence.   Adult river frogs are a dull green in colour, losing the vibrancy of their natal forms. They are able to climb out of the water to hunt insects on the trunks of trees, or on the forest floor during the drier season. They secret a thick milky substance to deter predators; it tastes foul, and other animals tend not to try to eat them more than once. The Imthic merfolk have found that this substance makes a strong topical anaesthetic, and have developed a method of harvesting it that does not antagonise the frogs too much.

I like how the Imthic merfolk never take more than half :)

The balance of nature is important to them. :)

I love that the natal form has a unique color. also, that merfolk take but do not harm the population, I love this!

An anaesthetic derived from thick milky frog excretions. I wonder how someone first discovered that it could be used in this way...   Awesome article Emy! You've inspired me to hop to some worldbuilding of my own (see what I did there?) :)

I love the relationships between them and the merfolk. It's a nice touch that the merfolk eat some but leave the rest, and that they try to collect the secretion without doing too much harm.

Thank you! They are aware how delicate their river ecosystem is. :)

Cute little frogs. It's interesting that they've adapted their reproduction to the rainy season. Do they notice that it's raining, or do they have other sensors that tell them this is the perfect time to spawn? And I hope the ponds in the more remote areas don't dry up.

Summer Camp is back! Rippling waves lead you to my answers of this year's prompts.

That's something I have to do more research on, for sure. Thank you, I hope they don't dry up either.
