Dental dermicles are found on which sea creature qnswer
Answers
Fish
Some fish do actually have teeth, and of the ones that do, a few are actually quite dangerous, even to humans, such as bluefish, barracudas, and piranhas. Others have only chompers in the back of their throats, so as to grind up their food before digestion.
Turtles
Turtles actually do not have teeth. Instead, they have what is referred to as beaks, which they use to grab, hold onto, and cut up food. Some turtles do have sharp ridges in their beaks that can act like teeth, but they do not have any in their jaws.
When born, they do have a single tooth, but it is used to break out of their egg, and is lost pretty quickly after they have hatched.
Even though turtles lack teeth, it does not mean they are harmless if they bite someone. They have incredible power in their jaws, and their beaks can be razor sharp.
Birds
Of course, birds are not sea creatures. However, many do feed on ocean creatures, spending most of their own lives on the water.
As many know, though, birds do not have teeth. They swallow food whole, gulping it down after catching it in their talons or beaks. Studies have been mentioned, however, that long ago, birds actually did have teeth.
Other Sea Creatures
In addition to the above, other sea creatures do have teeth as well, some of which you might not have known about.
Northern Elephant Seal
Purple Sea Urchin
Some squids
Some eels
Sea Lamprey
Bobbit Worm
There are even more, too many to list, but these are the most well known species that have teeth.
Shark contains dental dermicles which covers their skin to help them keep in right shape.
EXPLANATION:
The texture of the skin is rough and it has "small scales" similar to 'teeth' called dermal denticles. The aligned structure of these denticles is useful for maintaining the water channel over the body and hence minimizes the friction.
These dental grow 'throughout the life of the shark' as they grow. They protect "shark skin" from 'injuries' and from other harmful elements from water.
