Representatives of the U.S. Navy visited today and I am certainly more informed on what they do. Their career may be entirely different from person to person depending on the path you choose to take. Regardless of the path you take you must go to school first and go to boot camp. After that you're free to enjoy which ever path you took. What I found most interesting is how willingly these men were to give their life for this country. Like the younger said that if someone messes up in a submarine and they accidentally hit a rock then regardless they will probably sink. He stated that there goes 100 lives all because of one mistake. To be honest i didn't really learn much about the ocean at all. Everything they stated in the slides was stuff we had reviewed in class. Also, to be fair we didn't get that far into the power point. Honestly, something I will remember is Allen slamming down on my desk and yelling at me. At that point I was a little drowsy and it really gave me that wake up call.

Flukes are used to identify different whales. They are used to identify whales because every single fluke is unique to the whale. Scientists need this data in order to see the types of whales in each part of the ocean. Each fluke is different whether it be completely black, completely white, black with some white, some with scars, etc. The most difficult part of this lab was the fact that there were so many pictures. It was really difficult and frustrating if you're looking for a tail that is at the start of the packet and you miss it so then you're stuck looking until the end only to realize that the fluke match was on the second page. One way to definitely make it better, although the tails are only black and white, is by providing pictures in colors.
Over fishing is one of the few problems we have in the ocean currently. One of the ways we over fish is through the use of trawl nets. When the net us dragging across the bottom of the ocean in hopes of catching shrimp, the shrimp is not the only thing getting caught. Along with shrimps we catch a surprisingly overwhelming number of fish as well. We catch more fish than actual shrimp.When brought onto the fish the fisherman inspect what they have captured and even if dead they return the fish into the ocean. This is killing a variety of fish that should of been caught only for the hopes in catching shrimp. Ways we can help stop over fishing is by supporting our politicians to make the right choice.

Coral bleaching gets it's name due to the fact that the coral turns completely white. This happens in change in temperatures in the water causing the coral to excrete the algae within it. This affects the environment by mostly impacting the fish that rely on the coral. The coral eventually will die following the fish that require it to survive.
1. Ghost Fishing: Old fishing nets and fishing tools that are left in the ocean that continue to catch.
2. Entanglement: Fish or other marine animals that get caught in fishing lines or nets.
3. Plastic Bags: Plastic bags are mostly affecting sea turtles. Sea turtles mistake plastic bags for jelly fish which they then eat and most likely suffocate on.
4. Plastic Pellets: Animals mistake the pellets as food. Once they consume it the plastic doesn't break down in their stomach which causes them to never feel hungry and then they die from starvation.

Common Name: Lion fish
Scientific Name: Pterois antennata
Adaptations: The lion fish uses camouflage to adapt to his surroundings.
Hunting Strategies: The lion fish uses its spikes both as defense and offense. Each spike is filled with deadly poison which it uses to kill.
Reproduction: When a male and female lion fish are ready to reproduce they both change colors. The male becomes darker while the female becomes lighter.
Interesting Facts: Lion fish is one of the most venomous fish in the world. Lion fish can grow up to 16 inches long. They can be as small as 2 inches.
Why I chose it: I chose the lion fish because it looked interesting and it was on the list.

Sea grass are more salt tolerant in order to live in sea water. They also have specialized roots which help them against the currents.
There are only three types of animals that can eat the sea grass directly, others eat the detritus.
Residents: Residents are the animals that permanently live in the sea grass.
Migrants: Animals that come to feed on residents. They take shifts during the day and night taking turns eating.
Travelers: Large animals such as manatees, dolphins, and shark that also come for food.
