Plankton

Plankton are the most important part of the food web, because if plankton disappeared, it would create a domino effect and kill all other animals in the oceans. Because other plankton and small fish eat zooplankton, then small fish eat them, then bigger fish eat them, then squids eat then, then sharks. So even though sharks don't eat plankton, they would still die and go extinct if there was no plankton. 2 main categories are meroplankton and holoplankton. Meroplankton are plankton for only part of their lives usually the larval stage. Holoplankton are plankton for their entire lives. 3 benefits from plankton are: Immune booster, energy enhancer, and mood booster. They can effect your daily life by making you feel better and have more energy and be happier. 

Dinoflagellates

Dinoflagellates cause lots of problems, one of which is the Red Tide. The Red Tide is a phenomenon thats also called an algae bloom. Which is a large about of a microorganism, such as the dinoflagellates. And they take a color of red or a reddish-brown. Red tides are events in which estuarine, marine, or fresh water algae accumulate rapidly in the water column, resulting in coloration of the surface water. It is usually found in coastal areas. It caused neurological damage to humans, and it gets into things like clams tissues and toxicates them. it cannot be prevented because it is an algae bloom.   

Favorite Cephalopod

My favorite cephalopod would be Squids. The scientific name for a squid is Teuthida. The squids posses the same reproductive organs of humans. They mate normally also. Though after mating, the male dies shortly after. And the female dies after laying the eggs. She lays the eggs in egg shells for protection. They're anchored to the sea floor with other squid eggs; which the egg clumps look like flowers. Squid habitats: Some of them thrive in the warm tropic waters while others do much better in water that is at a lower temperature. You will find squid in just about all the major bodies of water found out there. They prefer salt water over fresh water. The squid will feed on small crustaceans and smaller fish. But humans prey on squid and larger sea creatures such as whales or sharks. The thing that makes squids special is their ability to change color or disguise. They will turn white when they need to look more aggressive to another male when fighting for a female. Interesting facts about squids: Squids have 3 hearts. The Big Fin Squid has 10 arms, not 8. Most live about a year. 

Marine instrument

The Automatic Identification System (AIS) is an automated
tracking system used on ships and by Vessel Traffic Services (VTS)
for identifying and locating vessels by electronically exchanging data
with other nearby ships and VTS stations. AIS transponders use two
different frequencies, VHF maritime channels 87B (161.975 MHz) and
88B (162.025 MHz). SCOUT has designed the KS-30 antenna to be
tuned on the AIS frequencies. Perfectly suited to the AIS radar and AIS Engine.

Plankton

Plankton are important because small fish, whales, and zooplankton eat it as regular food. And if phytoplankton didn't exist, those larger fish that eat the animals who eat the phytoplankton, would die out. They have adapted to make food and nutrients from the sun and the way they move in the water is adaptations. 

Phytoplankton: need sunlight for food and nutrients. 

Zooplankton: need the phytoplankton for food and nutrients. 

Favorite shark

I already posted about the Great White Shark, which is definitely my favorite and most intriguing shark. So I'll post about my second favorite, the Bull Shark! 

Scientific name: Carcharhinus leucas

Found in: Amazon River, Lake Nicaragua (can live in salt or fresh water

Reproduction: they mate in the late summer/early autumn. Pregnant for 12 months. Can have 4-10 pups. 

Predator/prey: Bull's eat mostly honey fish and sharks. Also includes turtles, birds, dolphins, etc. and humans catch and kill Bull Sharks. 

Adaptations: 1. adapted to live in freshwater 2. Has cartilage (no bones) 3. Have 2 dorsal fins.

Endangered/threatened?: they're near threatened. Why? Humans are catching them and not releasing them alive. 

3 facts: 1. Traveled as far up the Mississippi River as Illinios 2. Most responsible for near-shore shark attacks on humans, not great whites 3. Extremely territorial. 

Oceanographer

If I had to choose a oceanographer job, it would be a shark researcher. 

1. I've always had an interest in sharks

2. Sharks is one marine animal that is mysterious

3. You get to dive underwater with the sharks to observe them in shark-proof cages

4. You can also free dive and touch some if you get lucky

5. Just the ability to dive and touch/feed a shark to figure them out more would be the most amazing feeling
