Question 5

You are doing field study work with a scientist studying spiders in the Amazon rainforest.You come across a previously undiscovered species of spider and set up a video camera with a zoom lens to observe it closely without disturbing it.You see the female spider lay two eggs,kill an ant that tried to eat one of the eggs,and preserve the ant to feed the hatchlings the next day.She lays two more eggs as soon as the two offspring grow larger and leave.When your mentor asks for a monthly update,what exciting news do you have for her about this species?
