Carcharias taurus

Tony Strazzari Grey Nurse Shark (Carcharias taurus) -also sand tiger or ragged tooth shark shot very close up with a Canon G10 in Canon housing settings - focal length 6mm, f2, 1/250s. ISO200 using an idive video light.

Marcel Alveri Adis why must nurse

Tony Strazzari In Australia we call them 'Grey Nurse' ... not related to sharks that are called nurse sharks elsewhere. No idea why we started calling them grey nurse .... that is why I have included scientific and other names.

Marcel Alveri Adis yeah. it makes me think. what was mean of "nurse" maybe if we seen this shark it mean we close to nurse. like a bad signal. there must be a reason why. yeah who's know :) yeah but sometimes local name like that make easier us to remember species with many diversity like it

Tony Strazzari Have similar fins to nurse sharks but can't rest on the bottom, these swim fast and prey on fish.

Gram Hasselhoff it is an awesome shot, i really like it...i havent seen a shot like this before, that in itself says something

Andrew Wingate Grey Nurse at 9 mile Reef, Oz

Dave Walker isnt that a raggie or sand tiger shark ? or is it also called a grey nurse in oz ?

Tony Strazzari Yes ...in Australia we call them grey nurse but yes ...ragged tooth or sand tiger overseas...

Andrew Wingate They're all the same shark

Tony Strazzari Carcharias taurus to be technical..

Dave Walker great thanks for the info not exactly a beautiful shark but i will call it elegant lol

Tony Strazzari I dive with them all the time ... I think they're cute!

Pam Denise Turner Love the sharks but is this a nurse shark ?? Not by my recokening . .

Dave Walker yes a grey nurse shark aka raggie aka sand tiger

Tony Strazzari Pam the shark is called a grey nurse shark in Australia .... nothing to do with what are called nurse sharks elsewhere.

Pam Denise Turner Thanks Tony Strazzari for the clarrification . The nurse sharks in the fL Keys and Turks n Caicos do look entirely different !

Suzan Meldonian nurse shark?? lot of teeth for a nurse.

Tony Strazzari Carcharias taurus

Suzan Meldonian well I have learned something new today...never knew nurse sharks had teeth.This is called a Sand Tiger Shark, Carcharius taurus here. I see that they call this a nurse shark in Australia... how interesting .. please have a look at these sites for shark ids- this is Museum of natural history UF Ichthyology site id info. http://www.flmnh.ufl.edu/fish/Gallery/Descript/Sandtiger/Sandtiger.html as opposed to http://www.flmnh.ufl.edu/fish/Gallery/Descript/nurseshark/nurseshark.htm

Ron Silver These are much different from the nurse sharks we have in FL which have grinding plates rather than teeth. Highlights the problem(s) with common names.

Tony Strazzari Our Port Jackson sharks have grinding plates... but Ron you are right about common names ... can cause confusion the Carcharias taurus is not related to the other "nurse" sharks or tiger sharks for that matter either ...also we refer to the Odontaspis ferox as the sand tiger shark ... see http://australianmuseum.net.au/Odontaspididae-Grey-Nurse-Sharks/

Ron Silver Tony, you are preaching to the choir! I have been a strong proponent of including (whenever possible) the scientific names of species in photos along with the common names. Guess I was indoctrinated in my school days and utilized binomial nomenclature throughout my Federal career. Nonetheless, it certainly avoids a lot of confusion on IDs.

Suzan Meldonian what a riot... I've seen a lot of quibling over names on small critters, but never was aware of this in the shark world until now. I have to find you the link on the naming of nurse sharks- because they suckle... which I think would really be funky with your nurse shark! LOL
