Round Stingray
(Urobatis halleri)
The Round Stingray is a round, circular stingray that ranges from northern California down to Central America. They spend most of their time buried in the sand and foraging for food such as worms, crabs, and clams. Round stingrays have venomous barbs on their tail used for defense, oftentimes incidentally causing injuries to beach-goers here in southern California. These barbs are periodically shed and regrown throughout the year. We are currently investigating the biology, anatomy, morphology, and locomotion of the Round Stingray.
Studies
Studies
Pick Your Poison...or Venom?
Working with Dr. Jinae Roa of CSULA, we are investigating Round Stingray venom and venom cells.
What's the Point?: Morphological Studies of the Barb of the Round Stingray (Urobatis halleri)
Using a 3D modeling program called SlicerMorph, we are studying the morphological features of Round Stingray barbs.
Buried Alive: Sand Burial Behaviors of the Round Stingray (Urobatis halleri)
Round Stingrays use simultaneous movements in their snout, fins, and tail to bury themselves. We aim to quantify this behavior using high-speed cameras.
Surf's Up: Protection of Stingray-resistant Surf Booty
Working with our collaborator, Dragonskin, we looked into how protective their Surf Booty product was against stingray strikes.
If the Shoe Fits: Strike Response of the Round Stingray (Urobatis halleri) to Different Human Foot Sizes
We investigated how stingray strike responses may change in response to different foot sizes.
Urobatis halleri Strikes Back: 3D Tail Kinematics of the Round Stingray
We evaluated the kinematics of tail strike behavior by: describing the velocity and acceleration of the strike and estimating the force influenced by the barb.
Watch your step!: Stingray Sting Prevention
We tested the force at which the material, neoprene, failed to protect from a stingray strike.
