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!)
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.
