Gooseberry!
Isn't this thing super cool looking? This is called a sea gooseberry, or scientifically Pleurobrachia pileus. But lets just say the sea gooseberry. Many divers along the Norwegian coast come across these gooseberries. They float near the surface, and on night dives they can be spotted with just a flash light. Commonly they are found in rock pools and low tides. Can you imagine just flashing your light into the sea and seeing that?! So crazy. They are easily overlooked though because they are only 2.5 cm in diameter. They have two tentacles that can reach as much as 20 times their body length. Cool thing also about thier tentacles is that they can be retracted into pockets inside its body. They flash the rainbow colors because they retract light, and they are really pretty because of that. The rhythmic beating of the cilia allow them to swim. Some sea gooseberries will even eat each other for food. But they also eat fish eggs and larvae, molluscs, and copepod crustaceans. They catch their pray with their long tentacles, which they then real in to their mouth.
I found this REALLY cool video of the sea gooseberry and its movement. Man what an amazing creature!

Antibiotics!
The use of antibiotics in animals in factory farms totally should be regulated. I think it is awful to use antibiotics to make the animals bigger. Its like getting implants or collagen to have more food. Its fake! On the website it talks about using the antibiotics to help prevent diseases, which could be a nice thought, but I am pretty sure most people are using the antibiotics to make the animals bigger so they make more money.
I also think it is not cool because this whole idea is not only harming the animals, but it is making us humans ill as well. Where is the benefit then? I really hope this antibiotic thing gets regulated or even completely gotten rid of. Leave the animals alone and just make them natural!

Evolutionary Theory.
A theory is a "comprehensive explanation supported by abundant evidence". To say that evolution is a theory, it has evidence, but it cant be proven exactly. That doesn't mean it is not true, just not proven. Because of the evidence people chose to believe it, but not all people do. A lot of people take offense to evolution for a couple of reasons. One reason is that a lot of people don;t want to think that our smart and powerful people came from what they refer to as dumb monkeys. Although, apes are very intelligent, and people just don;t see it that way. When you do look at the similarities, it makes some sense. Another reason that people take offense is because people believe in God, and that God created man. (This is where I stand) I think people also don't believe it because they don;t see evolution happen, because it takes so long for noticeable change, that it doesn't even seem like change. I think it is just one of the explanations of the natural world. I am sure that Darwin and such people weren't trying to screw with peoples heads and bash on all the other beliefs out there. They observed things, and saw some sort of connection and ran with it. That is all. Just like all of the other theories out there.
