Thanks for doing this Sharky Sunday thing, it's my favorite time of the week (besides Finley Fridays). Quick question about sharks, seeing as I see their teeth a lot... how many rows of teeth do sharks have?
Lots of love,
Thanks for your question- and the praise!
To answer your question, most sharks have 5-15 rows of teeth in each jaw. Unlike our own human teeth, their teeth aren't rooted to the gums and are therefore easily broken off. When this happens, the tooth behind it (in the row behind the first row) moves up to take its place. This is sort of like a conveyor belt. As the shark grows, the teeth grow in size, too!
Hi Ms. Marquez!Mommy and I watch lots of shark week... is it true Great White Sharks jump up in the air?
Thank you. Colin
Thanks for your question! Yes, great white sharks jump in the air; they usually do this when going after a seal. Last week I shared an infographic about other sharks, like great whites, that jump up in the air.
Hello Ms. Marquez,
In the spirit of SHARK WEEK, can you tell us- quickly- what are the shark families?
Thanks for your question.
Quick and easy, huh? No better way to inform quickly than through an infographic! Learn about shark families- many ignored by Shark Week- in this infographic.
Is there a good visual about the dorsal fin parts of a shark? I was a bit confused about the porbeagle shark bit- until you showed the picture. I just want it for future reference. Thanks!
Congratulations on all the work!
So, what makes a shark a "shark," and not like other fish?
With all the crazy things shown on "Shark Week," I was wondering something that seems Sci-Fy worthy...... Do sharks cross-breed???
Thanks for answering! Love your blog, by the way.
Thanks for your question! Glad you like the blog!
To my knowledge- and if someone knows differently they can correct me- sharks stick to their own species when it comes to mating. Sort of how a bird wouldn't mate with a dog. Hybrid sharks have been found, though, the most famous being off the coast of Australia.
