Rocky intertidal zone


Spent the morning searching the rocky intertidal zone looking for organisms that live in these zones. We found a lot echinoderms, such as sun stars. Here I am holding a sun star with 23 arms. Juvenile sun stars start their lives with 5 arms and as they mature they may have up to 24 arms. On the picture below you can see their tube feet that they use to get around as well as their connection to water. -RM

Cholla Bay

Image
On Thursday we went to Cholla Bay to do some tide-pooling. A difference compared to other beaches we tide-pooled at was that It was flat with very little rocky areas until further on in the tide-pool. We saw many blue crabs, soft shell crabs, sea cucumbers, sand dollars, and some octopus in clam shells. However we noticed a fishing net washed ashore that may have come from illegal fishers and inside were 6 crabs that were barely alive. Noah, Noel, Sharon, Kristen and I spent upwards of 20 minutes carefully cutting and releasing the crabs back into the ocean. We then properly disposed of the fishing net afterwards. It's quite unfortunate that nobody picked up that net until we came along and disposed of it. It should be important for others to clean up even if the trash is not theirs inorder to keep the environment clean and not polluted. -Adel Redzepi

Walking sponge!!

Image
Day 1, wandering the intertidal area near CEDO. I turned over a rock and found a really unique looking sponge. As I have never seen one before i began taking photos and was completely caught off guard when it started walking!!! This actually turned out to be a species of crab that uniquely had a sponge attached to its shell which was growing successfully! Because the sponge and the crab both require similar environmental conditions this symbiosis is effectively providing the crab with a near perfect camouflage, while providing the sponge the unusual ability to move and remain in a wet location where it can collect food and prevent itself from absorbing too much air. As a sessile filter feeder this is not an ability it is typically afforded, providing an increased chance of survival in the intertidal zone where seawater is not always available. Super neat.

Some cool intertidal organisms

Image
  This decorater crab was wearing a hat! (made of sponge) This octopus inked so many times!     In the intertidal zone, we observed many different species. For example, one creature was the o ctopus; part of the Mollusk phylum. We observed the octopus use an ink spray as a form of self-defense in order to deter predators. We saw the organism ink several times in an attempt to scare us away. We also observed the 8 tentacles that are used by this organism to swim, hold things, and get around on land. This was the first of many octopi we would see!     We also saw a strange occurrence of a decorator crab using a chunk of sponge as a protective shell. It seems that the protective sponge also acts as a sort of camouflage in its environment, and helps to keep it safe from predators. These crabs are of the anthropoda phylum and must molt in order to grow. They also have 6 legs. In the second image, we observed a swimming crab. These  crabs are characterized by the...
