Continuing the questions from last night. The lad also wanted to confirm how fish mate, frogs breed and worms... just how to do worms figure this out mom?
So worms. The picture below comes from Nature Store (I THINK).

From Ehow I learned this: "Worms are relatively simple creatures, meaning that they don't have a bunch of special parts used in the mating process. While this may be true, they certainly have some unique parts that aren't found on other animals or insects. Located about 1/3 of the way down a worm's body is a soft fleshy ring that is thicker than the rest of the body. This ring is called the clitellum, and it is very important in the mating process of a worm. When a worm is ready to mate, the clitellum changes colors. Normally a fleshy pink color like the rest of the worm, it will turn red-orange in color when the worm is looking to mate. Two worms with this dark colored clitellum will find each other and then begin to go through the lengthy process of reproduction until they are ready to give birth."
From Hubpages this: "Each worm has four pair of setae, these are like bristles on a hairbrush and can be extended out or retracted into the worm body. The third set of setae is used in the mating process. They are used to hold the earthworms together while mating. These setae actually penetrate the mate’s body during the mating act. Once they are in position, sperm from each worm passes to the other and is collected and stored in special sacks. The process lasts 2 to 3 hours! The earthworms separate and go back to their tunnels. "
Which is also where the picture below is from.

Pretty neat huh?
And now on to frogs. The lad caught LOTS of frogs on vacation this summer.

The male frog fertilizes the eggs as they are laid. :) I knew this but needed to confirm it for the lad who can't for the life of him understand why the male frog would need to sit on the female frog if he isn't putting his sperm inside of her. I explained to him that he grabs her so that he is the the right place to fertilize them when they come out. Frogs are different than mammals in how they make their babies.
All about frogs helps explain it. :)
And this video below doesn't do a great job of showing the results of mating, but it gives a general idea.
