July 14 – Shark Awareness Day

Posted on July 14, 2015


There seems to be some disagreement about when Shark Awareness Day is – is it July 14? July 15? July 17? – but I figure, with shark attacks being in the news right now, let's start as soon as possible and keep on talking about sharks all week!

So – are sharks a huge danger to humans? Or is it more fair to say that the reverse is true?

Believe it or not, even with North Carolina reporting (at the time of my writing) eight shark attacks in just three weeks (!). we are still much more of a danger to sharks than they are to us.

First, why would I say such a nutty thing right after typing “eight shark attacks in just three weeks”?

NOTE: This is NOT what
the waters of North Carolina
look like right now!
Well, scientists tell us that the sharks off the coast of North Carolina are not suddenly craving human snacks. Instead, weather and population booms in the sharks' favorite fishy food means that there are a lot more sharks a lot closer to shore, and they are snapping at splashing creatures assuming that they are fish. The shark attacks were not gulp-gulp-yum! sorts of attacks – instead, the sharks bit and then let go. We can assume that once the sharks realized that they'd bitten into such a relatively large creature, and/or that the creature they'd bitten didn't taste fishy, they let go. No humans died in these encounters. (To read more about the NC attacks, check out this article.) 

Also, when we hear that there are more shark attacks, we automatically feel that we are in more danger. But in actual fact, more people are in the water, so the RATE of attacks (in most places) have actually dropped. People in California, for example, are a lot – lot – lot – lot safer now than ever. Check out this article, which shows that an individual's risk has dropped by more than 90%!! 

So, how many people die in shark attacks each year? Last year only three people died, in the entire world, from shark attacks. Some years it's more like ten human deaths from sharks.

In contrast, how 100 to 270 MILLION sharks are killed each year by humans!

To really get this contrast, check out this infographic, comparing how many people sharks kill per year to how many sharks people kill PER HOUR. It makes the point!

August 30 – International Whale Shark Day

Posted August 30, 2013

What's the world's largest living fish?
What fish grows to be from 40 to 50 feet long?
What fish has a mouth about 4 to 5 feet wide but feeds on some of the teeniest creatures around?

I'm sure you've guessed that the answer to all these questions is the whale shark, a gentle, plankton-eating shark.

Whale sharks are a kind of shark. They are NOT a kind of whale, but their size is similar to the size of some whales, and their feeding habits are similar to those of baleen whales, who also eat tiny plankton. Although whale sharks have a lot of teeth (around 3,000, in fact!), their teeth are tiny and of little use. Instead of using teeth to bite food, whale sharks use gill rakers to filter food from huge mouthfuls of ocean water; this is similar to whales using baleen to filter their food.

Whale sharks swim in all tropical and warm-temperate oceans, so there are many names for them in various languages. In Latin America, they are commonly called “domino,” because of the spots on their backs, but in Madagascar and Java their names translate to “many stars” and “stars on the back.” Kenyans call the whale shark “papa shillingi,” which refers to a story of a god tossing coins called shillings onto the creatures' backs, giving them their spots.

Because whale sharks migrate every year to the shores of the Mexican state Quintana Roo, on the Yucatan peninsula, a reserve has been established there to protect these huge creatures. Several Asian countries, including the Philippines, Taiwan, and India, have banned killing whale sharks, although enforcement of these laws is difficult. 

Divers love to spot these peaceful creatures—so maybe tourism can help motivate people to protect whale sharks.

By the way...

This chart compares the size of:
a human in blue,
a great white shark in green,
a whale shark in purple,
and estimates of the size of
 
megalodon in red and gray.
I have said that the whale shark is the world's largest living fish. But megalodon, a prehistoric shark, was even larger—up to 59 feet (18 m) long! And megalodon wasn't a filter feeder with teeny teeth! It was a lot like a much larger version of a great white shark, with huge jaws and enormous teeth! Yi-ikes!

Take a peek at just one megalodon tooth, below. How'd you like to meet up with jaws full of these teeth?

A blue whale is not a fish (it's a mammal), but a size comparison shows that this largest of all living creatures is between 80 to 100 feet (around 30 m), with the very largest measuring 110 feet (33.5 m). Did you know that today's blue whale is the largest animal EVER to have lived, that we know of? None of the dinosaurs or dinosaur-era ocean creatures (at least, that we have fossils of) were larger.
