| Winghead Shark (Eusphyra blochii) |

| Scalloped Bonnet Shark (Sphyrna corona) |
 |
| Whitefin Hammerhead Shark (Sphyrna couardi) |
 |
| Scalloped Hammerhead Shark (Sphyrna leweni) |
 |
| Scoophead Shark (Sphyrna media) |
 |
| Great Hammerhead Shark (Sphyrna mokarran) |
 |
| Bonnethead Shark (Sphyrna tiburo) |
 |
| Smalleye Hammerhead Shark (Sphyrna tudes) |
 |
| Smooth Hammerhead Shark (Sphyrna zygaena) |
 |
| Hammerhead Sharks (Genus Sphyrna) |
Since I had maps for all known species of Sphyrna, I went ahead and combined them all into a map for the genus as a whole.
 |
| Hammerhead Sharks (Family Sphyrnidae) |
And then, since there's just one more species of hammerhead (Eusphyra blochii), I also made a distribution map for all hammerhead sharks. The only difference between this map and the previous one is the seas around the islands of Borneo and Sulawesi.

So I'm wondering, are these sharks really only around shores, or is that the information we have because that's where humans encounter them? Would we be safe from sharks out in the middle of the ocean?
ReplyDeleteAlso...oh my goodness! When I saw you updated your blog I thought (and hoped) you had written about your ultrasound! Not that sharks aren't exciting!
Per your first question, those are only areas where they have been observed. Since some of them are found on both sides of the Atlantic it is assumed that they can be found on the open sea, but that is not indicated in these maps.
ReplyDeletePer your second coment, they didn't give us any digital copies of the ultrasound, this time, only a printout from a thermal printer. And without pictures it just didn't seem worth it to do a post.
