Jaws-and the Coral Reef

A few weeks ago, while the kids were gone to their grandmother’s and I was able to just sit on the couch and eat bon bon’s and be a total lazy butt, I chose to watch Nat Geo via Disney Plus on the Roku. The show that caught my interest the most, Sharks of Lost Island. This documentary was super informative! It takes place on some remote islands in the British territory. I am not going to tell you about the whole documentary-go watch it and make your kids watch hit too. It’s not near as flashy as cartoons, but it is still pretty neat-my kids love to watch animal shows!

Sharks were the main point of the documentary. I have to admit, my shark knowledge is pretty much limited to “try not to get eaten by a shark today” while body surfing in South Carolina. 🤷‍♀️ You think of sharks as this menacing creature who is out to snack on beach-goers like we snack on popcorn, but they are actually important to our ecosystem. How, you ask? Well, here’s what I learned….

Reef sharks looking for some bites

As we discussed yesterday, the coral reef is vital for all kinds of reasons! Lots of different kinds of fish hide from the sharks in the coral reefs. So a healthy coral reef is covered in sharks tryna find a snacky snack. Humans keep fishing for sharks-a lot of the time for monetary value, which is making things discombobulated down there on the reefs. Less sharks eating all the different variety of fishes means other fish, like groupers, keep growing in abundance (growing in like, schools of fish, not physical size of the grouper) and they eat up all herbivore fish. An example of an herbivore fish is Dory. She is actually called a surgeon fish or a Paracanthurus hepatus. With fewer little Dory’s swimming around the reefs, macroalgae grows like, well, a weed. What happens when you don’t weed your garden? All the useless stuff takes over your pretty flower beds or mater plants or what have you. If your garden is covered in weeds, it’s gonna be hard to have a good crop season, right? So this macroalgae totally affects the coral reefs. It practically smothers it to death. Below is a picture that helps explain all the words I just said. I got this picture from here.

Food Chain of the Reefs

Another reason the sharks are dwindling around the coral reefs is due to-dun, dun, dun….PLASTIC WASTE. Yes, we are back there again. Hundreds of sharks and rays are dying after getting tangled in drifting “ghost nets” and plastic waste, according to new research. Poor Bruce the shark.😪

Have any of these articles helped you become more conscience about how wasteful we can be? Comment below! I’d love to hear all about it.
