Stingray smile!
I think this fish smiling to me
a bottom-dwelling marine ray with a flattened diamond-shaped body and a long poisonous serrated spine at the base of the tail.
Stingrays are a group of sea rays, which are cartilaginous fish related to sharks. Many species are endangered. They are classified in the suborder Myliobatoidei of the order Myliobatiformes and consist of eight families: Hexatrygonidae (sixgill stingray), Plesiobatidae (deepwater stingray), Urolophidae (stingarees), Urotrygonidae (round rays), Dasyatidae (whiptail stingrays), Potamotrygonidae (river stingrays), Gymnuridae (butterfly rays), and Myliobatidae (eagle rays)
The mouth of the stingray is located on the ventral side of the vertebrate. Stringrays exhibit euhyostyly jaw suspension, which means that the mandibular arch is only suspended by an articulation with the hyomandibula. This type of suspensions allows for the upper jaw to have high mobility and protrude outward.
The teeth are modified placoid scales that are regularly shed and replaced.
In general, the teeth have a root implanted within the connective tissue and a visible portion of the tooth, is large and flat, allowing them to crush the bodies of hard shelled prey.Male stingrays display sexual dimorphism by developing cusp, or pointed ends, to some of their teeth. During mating season, some stingray species fully change their tooth morphology which then returns to baseline during non-mating seasons.
