2) Female blue crabs only mate once
3) The blue crab can lay up to 8 millions eggs! But it depends on how big the female is.
4) Blue crabs will shed their shell to make a new one. This process is called molting.
5) Blue crabs have teeth in their stomaches so they can "chew" their food.

This is because of the detritus and the fish that swim above the mud. Blue crabs prefer brackish water with a nice mixture of salt and fresh water. ]]> 2017-10-20 18:34:43 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199179832 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199180280 2017-10-20 18:36:08 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199180280 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199180573 2017-10-20 18:36:59 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199180573 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199993121 Barnacles, leeches and worms will attach themselves to the blue crabs shell and the crab will travel around the marsh. The organisms that have attached to the crab will release and the predators of those animals will eat them. This helps spread out the worms that will help the plants and the will spread out the prey. Sacculina barnacles will attach themselves to crab and feed on the fluids of the crab that prevents them from reproducing. This is a parasidic relationship. ]]> 2017-10-24 14:09:12 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/199993121 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/200005413 Callinectes sapidus is the blue crab scientific name. It translates to "Beautiful Swimmer" ]]> 2017-10-24 14:27:40 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/200005413 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/203967871 After the blue crab is hatched from it's egg it is a Zoea. This is a microscopic animal stage. Then it will evolve into a megalopae which is bigger and has developed claws and defined appendages. The next is a juvenile crab that is clearly a blue crab. Once the crab has molted (definition at fun fact 4) about 20 times it'll be fully mature. Depending on the sex of the crab, the female will mate and create a sponge to lay eggs. If a male it will mate and then die.   ]]> 2017-11-06 16:21:24 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/203967871 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/203973299 2017-11-06 16:29:53 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/203973299 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/203979033 2017-11-06 16:39:06 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/203979033 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/204389883 There are many threats to the blue crab. One of the most common is the destruction and harming of their habitats. Hypoxia is when there a low concentration of oxygen in the water. Green and Blue algal will mix which will cause algal bloom and they will take up the oxygen in the water. This will cause hypoxia and the algae will release a lot of nutrience in the water. This is bad for the blue crab and other organisms. ( click this link to learn more about Algal blooms)

The blue crabs will move to shallow water to find more oxygen. But this will cause them to be more open to predators and fishing gear. ]]> 2017-11-07 15:15:40 UTC https://padlet.com/brogan1/THE_BLUE_CRAB/wish/204389883 brogan1 https://padlet.com/brogan1/THE_BLUE_CRAB/wish/204570065 http://www.mdsg.umd.edu/sites/default/files/files/EBFM-Blue-Crab-Summary.pdf
