Love is in the water

I have always thought of photographing frogs at night but didn’t do it. Mainly due to my enormous laziness. But a few days back when I returned from work I heard the frogs were calling their hearts out. We have pumped out the water of our pond and there many frogs gathered. So I thought this is the day. I changed dress took out my camera and went looking for frogs.

 Armed with a mini flashlight when I entered the area suddenly all frogs stopped calling. Only after a few silent and dark minutes they started to call one by one. Except a few species only the male frogs call. The females choose the males based on their call. By analysing the call, females can identify species, size, health etc of the male frog. Frog call also has many different purpose. They announce there presence with it, they impress the females for mating with it, they also deter rivals with call. But this call also attracts predators. So they have to be alert too. Calling is also physically very demanding for them.

So following the call I mainly found indian cricket frogs there. Two big sized bull frog were also there. Then I found a checkered keelback water snake waiting patiently at the edge of water for a tasty frog dinner. At the same time, from the other side of the pond I heard the distinct sound of a dying frog captured by a snake. When these non venomous snakes, checkered keelback, rat snake etc catch a frog, they dont kill the frog, instead directly swallow the frog. At this time frogs make a typical sound, once heard you will never mistake it to identify. But where are the couples?? 

This was not a rainy day. So there was no mating frenzy. After searching for some time I found a couple of cricket frog. They were in amplexus. This is a typical pose found in many external fertilisation species but mainly in amphibians. The male climbs up the back of the female and grasp her in the throat, armpit or belly region with their forearm. This way when the female frog releases egg, the male can simultaneously release sperm to facilitate the external fertilisation of their eggs. Frogs show many different type of parental behaviour. Frogs like our cricket frog, pond frog, indian toad etc who show no parental work, they rely on enormous number of eggs. On the other extreme poison dart frog of amazon rainforest lays only a few eggs. Then after hatching they carry the tadpoles on their back and deposit them on their individual pool singly. The female frog supply the tadpoles with unfertilised egg as food until they transform as a frog. There are many other type of example in between. 

After spotting this couple, I couldn’t find any other. Waited for ling, donated atleast a litre blood to mosquitoes but still no success. So I called it a day. This was a good experience. I had to try it in other places also to find other frog species in amplexus. 

Jumping Chicken (Frog Meat Trade)

A few days back when I was browsing Facebook, I stumbled upon an interesting cartoon. It was about frog meat industry. I got interested and tried to find out more. A little bit of searching and reading brought out some anxious facts.

In contrary to my belief that only tribal and rural people eats frogs, it is a delicacy among the people of 1st world countries. Even they have depleted their frog population so much that they are forced to import it from third world countries of Latin America and South-east Asia. Currently Indonesia is the biggest exporter of frog legs. It exports about 142 million frogs each year and about 7times of this number is consumed in the country. Thailand, China, Malaysia, Brazil and several other countries also exports frog legs. Frog legs are popular in south east Asian countries but they are in huge demand in countries like France, Italy, USA etc. even Mr. Barak Obama was seen eating frog legs in a party. This demand has resulted in the disappearance of many frog species and several other species have become rare. A few countries have set up frog farms to supply the demand but still most of the frogs come from the wild.

What is the actual impact of this? A few years back India was the biggest exporter of frog legs. This trade was so popular that frogs were called jumping chicken. But India has banned this trade in 1987. Bangladesh has also banned it in 1990. They must have good reasons to so. This frog meat trade does not affect all frog species. It only targets the bigger species. In India, the targeted species were Indian Pond Frog(Euphlyctis cyanophlyctis), Indian Bull Frog(Hoplobatrachus tigerinus), Jerdon’s Bull Frog(Hoplobatrachus crassus). Frogs are a natural insecticide. They eat a whole lot of insects, molluscs and other things that damages our crop production. And the bigger the frog, the more insect it can eat. Not only in frog stage, in the tadpole stage also it helps us by cleaning up the water. Now when we picked up frogs from the environment, the insect population multiplied considerably and crop damage also have increased. The problem became so severe in India that the revenue lost due to crop damage far exceeded the revenue generated through frog leg exporting. Same thing has happened with Bangladesh and same thing will happen with the other countries too. Frogs are an important part of our eco-system and removing them from it is not a wise decision.

Indian Bull Frog

15yrs after banning the trade, frog population in India has revived itself and the species are not in danger anymore. But thanks to Mr. Manjunath Sullolli an image from Goa brings out the question again, “has the trade really stopped in India?” Actually as long as there will be demand in the market, some people will always be ready to supply. If only we can change our taste for frog meat, the frogs can really be saved.
