It must be the grasshopper.
The mole doesn't sing. Neither does an earthworm. And the figeater beetle makes other noises, and is not even found in our region.

Hi all,
I have 5 Questions for you to start with. These are on all animals of the world
Here is the first one see how you get on.


Correct Answer: Grasshopper (Melanoplus differentialis)
The grasshopper (Melanoplus differentialis) can woo his partner with many different types of songs. The male grasshopper has different songs for each step of the mating period. The grasshopper's mating songs are created by a form of friction when he presses his hind legs or his strong and tough front wings against other parts of his body. He then move his legs or wings back and forth. He can make different music for other reasons too. An example of this is when he attempts to defend his territory. Another example is when he is calling to locate other grasshoppers. The autumn is when most of the courting songs are heard.

Remember animals of the world
This particular spider is actually considered to be a lot like a cat when it hunts. Can you identify which spider I am talking about?

I reckon, on this Valentine's Day, men should stop and contemplate the wonderful lessons we could learn from the courting grasshopper. :clap:

Now for the spider in question, which is probably less instructive in the ways of courting. :hmz:

Shangri-La asked: "This particular spider is actually considered to be a lot like a cat when it hunts. Can you identify which spider I am talking about?"

Is it the lynx spider of Australia that you are referring to?

The correct answer was Green lynx spider (Peucetia viridans).
The green lynx spider(Peucetia viridans) is generally found on grass, low plants and hedges. This type of spider has long legs which aid in the hunt for prey. This spider is an excellent hunter. Due to its ability to run and jump onto its victims, like a cat does, the spider is called a lynx spider.
This spider doesn't make webs because it is an active hunter. The lynx spider has two large eyes in the front of its head as well as a smaller pair. It has two eyes on the sides of its head. It also has two large eyes looking above and backward which gives it a very wide range of view. The lynx spider generally hunts in the day time and prefers it when it is sunny outside. It can run and jump over grass and leaves in its pursuit of victims.
The male is quite large for a male spider. His palpal organs, which are located on his head on each side of his jaw, are used to transfer the sperm to the female spider. The male uses a special sperm web, which he produces, to pull a drop of semen from his rear to the palps on his head. He then uses these palps to insert the semen into the female

Remember animals of the world
There is a very unusual creature which can actually change dry seeds that they eat into water. Do you know which type of animal has this capability?

Answer: Desert kangaroo rat (Dipodomys heermanni)
The kangaroo rat (Dipodomys heermanni) is a really unique creature. It can survive with very little water due to the fact that it has the ability to convert the dry seeds that he eats into water through a process called oxidative phosphorylation. All mammals have this ability, however the kangaroo rat is more adept at conserving the water that he produces. This creature does not pant or sweat in order to keep cool. It has a kidney system that is very specialized and allows waste materials to leave its body without much water output. It lives in moist and humid burrows, only coming out at night. Although the kangaroo rat does not store water, it still has a water content in its body that is about the same as other animals.

The round stingray (Urolophus halleri) mates during the months of January to March. The female has a rather unusual way of attracting her mate. How does she accomplish this?

The females "create" a positive electric field somewhere behind their eyes which attrack the males.

I agree! maybe add a little ... the electric fields are emitted from the spiracles behind each eye to attract the males. In order to maintain enough contact for copulation, the male must bite at the anterier of the female discs -if he bites at the posterior of the female discs she will often escape.

The correct answer was emits a localized positive electric field.
The female round stingray (Urolophus halleri) has spiracles (gill slits) behind each eye. From here, she emits a positive electric field which attracts the male. Once he is attracted then the behavior of mating begins. He will often bite the front of her body along the disc. She does not like that and will often escape from the male. When that happens there is no mating. He will then bite the rear area of the female. She does not make any attempt to escape from him when he is biting at her posterior. This biting maintains the contact between the male and the female during the time that they are mating.

This creature starts out its mating ritual by doing a circling dance of nuptials. Can you figure out which odd creature this could be?
