What an interesting and great day!  Today we woke up bright and early to go to the tide pools on mi playa.  While we were there we measured the salinity and the temperature of the different pools.  I enjoyed seeing all of the different organisms that live in the tide pools.  Then we went to the negative estuary, where we kayaked.  My favorite part of the day was in the estuary on the mud flats. When I walked around in the sand, bubbles would come out toward my knees and to the surface. 

While in the tide pool I learned that it is not best to touch fire worms because they are harmful.  I also found out that some anemones eat Brittle star fish.  One thing I found very interesting was the reason why the bubbles emerged, which is because of detritus and animals such as worms crabs and snails.  Detritus is dead organic organisms and the animals contribute to the bubbles by creating burrows (homes).  The estuary we saw used to be a positive estuary but now it is a negative estuary because their is less fresh water entering the estuary.  Another thing I enjoyed learning about was the fiddler crabs.  The male crab has one large claw and one small one. The small one is used for eating and the large one is used for attracting females.  When a female is interested the check out his burrow and decide if they will mate with them.  Another thing I learned was that most of the creatures in the tide pools are not harmful to people.
