Scientific Classification
Kingdom:Animalia
Phylum:Chordata
Class:Chondrichthyes
Order:Lamniformes
Family:Odontaspididae
Genus:Odontaspis
Species:Odontaspis ferox
Common name:Smalltooth Sand Tiger, bumpytail ragged-tooth
The Smalltooth sand tiger is a species of Mackerel shark, and like other more well known
Lamniformes, such as the Great White and the extinct Megalodon,
they have 2 dorsal, 1 anal fin, five gill slits, and eyes without nictitating membranes.
Growing to around 4.1m and up to 289kg with a formidable appearance,
they are non aggressive to humans unless provoked.
They are known to stop, gape their large mouth, showing many projecting sharp teeth,
turn around and shake their tail as a warning.
A rare species found in deep rocky habitats and sometimes shallows,
occuring worldwide in tropical and warm waters.
It is distinguished from the similar common Grey Nurse shark
in having a larger and further forward first dorsal fin and large round pupils.
Smalltooth sand tigers are predators of bottom dwelling bony and cartilaginous
fish and invertebrates, such as squid and shrimp.
Larger prey items, such as a 1.3m long kitefin shark, have been discovered in the stomach of a 2.9 m male from New Caledonia.
Pregnant Smalltooth sandtigers, possibly like this one, are poorly understood, and are presumed to be Ovoviviparous
(embryos remain in eggs inside the mother until hatching) like other Mackerel sharks.
Juveniles tend to stay below 200m, probably to avoid shallow water predators like the Great White Shark.
Adults have no predators apart from Man.
Due to insufficient data, maturity length can only be estimated from the Sand Tiger (C. taurus), as 200cm to 250cm for males and 300cm to 350cm for females.
Similarly estimated maturity and maximimum age of 6 yrs for females and a max age of 35yrs.
Smalltooth Sandtigers, like other sharks, are impacted by fishing,the unregulated shark fin trade, habitat loss and pollution.
Due to their likely low rate of reproduction even small impacts on their population may lead to local or even species extinction.
Smalltooth sand tigers, whose fossils date back some 5.3 to 3.6 million yrs, need better protection if they are to remain in our seas.

Amazing footage. Thank you for sharing.
Glad you enjoyed it, and thanks for commenting.
he living peacefully in his place with his pace. Odontaspis is relatively have solitare behave😮
This shark is so adorable. He do not looks fierce "ferox".
It's a Sixgill Stingray, Hexatrygon bickelli
I re-watched the video and couldn't spot a Hexatrygon bickelli in the footage. Odontaspis ferox and Hexatrygon bickelli are difficult to confuse with one another. If I have time I may make a video on it though.
Can we find this shark in aquariums?
I did a quick internet search and couldn't find any. That maybe because they are a large, vulnerable deep water species that is protected in some of it's range, and they might not adapt to captivity. Although it would be nice to see one up close in a public aquarium I am not sure the conservation value in public education would justify the time, expense and cruelty of taking one from the wild.
Why is there no footage like for their relative species bigeye sandtiger 'noronhai' at all?
Probably because they are rare (or rarely caught which may be due to a low population size or they occur in areas not yet fished commercially), and because only a small part of the worlds oceans have been explored and captured on video.
