The oarfish is the longest bony fish in the world -- there have even been some reports of fish up to 50 feet long (and weighing up to 600 pounds)! They are so long that many believe that these fish are the cause of some early tales of sea serpents and sea monsters. Because of its sinuous body, it is occasionally called the ribbonfish.
The final FOTD for Shark Week is on the fascinating great white shark, or white shark. Despite their reputation as man-eaters, great white sharks are actually more threatened by humans than vice versa.
Today’s FOTD is about the beautiful zebra shark. These sharks get their name from the impressive stripes found on the juveniles.
As they grow into adulthood, these stripes change into spots, which is why this shark is occasionally also called the leopard shark. (Taxonomists even originally thought that juvenile zebra sharks were actually a different species than the adult zebra sharks because their markings are so different!)
As you know, Oceana is a partner in Discovery’s Shark Week this year. Meanwhile, Discovery is a partner of this summer’s X-Games, so they asked artists to design and paint shark-themed skateboard decks to display at their X-Games tent.
The results are beautiful, and you can now bid on the skateboard decks online. The proceeds go directly to Oceana to help our shark conservation efforts.
There are some really cool ones -- check ‘em out!
Today’s FOTD is brought to you by the letter C, which is for cookie…and cookiecutter shark.
Unlike most of the other sharks I’ve written about so far, the cookiecutter shark is a relatively small shark; they only reach about 20 inches in length. Like some other sharks, such as great white sharks, female cookiecutters are larger than their male counterparts.
Despite their small size, these sharks still have quite a bite. They latch onto their prey and create suction with their large lips. Then they use their powerful jaws and many teeth to carve a circular chunk of flesh out of the unlucky victim. (Get it? Like a carnivorous, marine cookiecutter?)
Cookiecutter sharks attack large fish like tuna or even whales and dolphins; the prey usually survives the attack but the telltale round scar remains. They are also bioluminescent; they have a patch on their bellies that glows in the dark, deep waters where they live. They use their bioluminescence to attract potential prey.
See you tomorrow for another shark FOTD and I hope you’re enjoying Shark Week as much as I am!
You asked for it so here it is: a FOTD on the sandtiger shark!
Sandtiger sharks go by many names including the ragged-tooth shark and the gray nurse shark. When unprovoked, these sharks are fairly docile, despite their frightening appearance.
Female sandtiger sharks give birth to two live pups, one from each of their two uteri. Because of the relatively small litter size, sandtiger shark populations have a particularly slow growth rate and it takes them a long time to recover from population decreases.
Shark Week started last night! (And how great was ‘Ultimate Air Jaws?!”)
Oceana is a partner in Shark Week this year, and it’s my favorite week of the year, so I’m going to keep the celebration going with daily shark facts!
The scalloped hammerhead shark is just one of the many species of hammerhead shark, all of which have the characteristic t-shaped head.
Only one more week until Shark Week!
So in preparation for the upcoming shark fest, today we will talk about the basking shark. Basking sharks are the second largest fish in the world. (Pop quiz - what is the largest fish in the world? I’ll give you a hint: I have already written a FOTD about this kind of shark.)
These sharks are filter feeders so they just swim around with their mouths open, collecting plankton and other tiny creatures while filtering out hundreds of thousands of gallons of water every hour. The water is filtered through the shark’s characteristically large gill slits on the sides of its head.

Oceana board member Ted Danson was on the Late Late Show with Craig Ferguson a few nights ago, and after they discussed, among other things, Larry David’s germophobia, they bantered about the oceans.
Ferguson, who is hosting Discovery’s Shark Week starting August 1, recently swam with sharks in the Caribbean. He also made a shark PSA for us -- stay tuned for that.
In the meantime, watch their ocean banter:
Hello, shark fans!
While I generally don’t take advice from 30 Rock’s Tracy Morgan, I do try to “live every week like it’s Shark Week.” But as you may know, the real Shark Week starts August 1 and this year Oceana is an official partner with Discovery, so get ready for even more shark-filled fun and conservation.
I’ve been excited for weeks now so when I ran into the “What Kind of Shark Are You?” quiz on Discovery’s website, I had to check it out. After answering the 10 questions I discovered that I am…a great white shark!
What kind of shark are you? Take the quiz and let us know your results!
