Wildlife Conservation - Population Sampling

 
Today we learned how to calculate the population of species in an area. 
We dragged nets through the bay and put all the fish and organisms we found into a bucket of ocean water.  We counted each species we found and labeled it on a chart.  
Taking more samples over time gives you a better idea of how the area is doing.
 
Now we know what kinds of fish are in abundance, and which ones aren't thriving.
 

These are some Portuguese Man-O-War Jelly fish - their sting can be deadly. 






This creature is called a Sea Hare - It's a slug looking thing that eats Sea Lettuce (like a rabbit) hence the name.  It has two tentacles sticking out the top of his head and his end is narrow.
