Summary:
There is a lot of researchers wanting to study Great Whites as they seem to be a fascinating species. Their past is hard to figure out because their cartilage disappears in seawater, but old shark teeth help scientists. Sharks hunt a lot of seals and when seals occupy the waters of Cape Cod Great Whites follow. They use their vision and an acute sense of smell to help them find their prey.

3 Main Ideas:
- Great White sharks can live to 70 years old and males will reach their sexual maturity around 26 while females will reach it around 33.
- They have unusually large livers that allow them to withhold 2,000 liters of liquid blubber most of which they get from seals.
- A shark's fins on its top, bottom, and sides keep it stabilized and keep it mobile and flexible.

Relation to class:
We have been studying whales and now moving into studying sharks in their marine environments. This video went in-depth into the Great White species and their somewhat relation to whales as well.

Most Interesting:
I found it interesting that people are now accepting sharks more post Jaws because I am terrified of sharks.

Summary:
Coastal seas provide a lot of food for humanity and wildlife. Shallow seas are really important for aiding climate change because seagrass is helpful in absorbing carbon dioxide, along with mangroves. Overfishing has reduced the shark population by 90 percent across the world. Shows how animals like sharks, dolphins, seals, etc. hunt for their food. Without living corals, in those ecosystems, the other animals belonging to the same can die off and over the next few decades, the rest of coral reefs could be gone. Sea otters keep down the number of sea urchins as it is one of their food sources, but if they are not eaten they are spread out all over the ocean floor taking over. When the sea urchins are unchecked the kelp forests do not survive and other animals who need kelp to survive can disappear. Herring gather to breed, but predators know this and will wait for them, their predators are sea lions, bald eagles, and humpback whales (which can eat a ton of fish a day). Seabirds (that look like penguins) would survive on coastal sides of deserts until 50 years ago when the fish populations in the ocean were diminished, but luckily organizations helped bring the population back and the seabirds can thrive again.

3 main ideas:
- Animals that are hunters are extremely efficient when working together. Some animals, like the dolphins, heard their prey to an area they can't escape and the dolphins also jump around to catch certain fish like fly fish
- When sharks hunt for their food it helps that they are really good at detecting the slightest movements. If any of their prey breaks cover they are in extreme danger. The sharks go in big herds when hunting for their fish. The white tip sharks can be more dangerous because of their ability to get into smaller places and it is worse for the fish in the coral reef because there are twice the sharks they need to swim away from.
- Fish at the bottom of the food chain in the coral reef ecosystem eat parasites and other things cleaning off the corals. The warm seas are causing the corals in that ecosystem to bleach and they can eventually die. The excess carbon dioxide in our world is causing all of these changes.

Relation to class:
How different animals hunt within their ecosystems and how climate change is affecting our coastal seas.

Most interesting:
Bottlenose dolphins use echolocation to search for their food

Summary: During each month the tide's size and strength change. When the tide is lower it is nice for land animals to get food, but when it rises again invertebrates are the fortunate ones. Animals in their ecosystems are like giant families. They do most things together, but they also have the same reactions and mannerisms to things happening around them. It is like the way of living as their species is ingrained in their mind from the start. The temperature seemed to affect most changes for the animals, either directly or indirectly.

Main Ideas:
- After the new moon and the full moon is when the biggest tides happen
- When the tide is low it allows animals like raccoons to eat some seafood
- Animals have to react to predators in their living space and the environmental changes too (the video showed many different examples like the penguins hiding from the seal)

Relation to class:
The video was describing different animals and how the environments around them affect their lifestyle. This relates to ecosystems.

Most interesting:
I found it interesting how the species featured in the video seem to all be in sync in their decision-making, but I would say that humans are the one type of animal that doesn't have one specific reaction to environmental changes.
