The round stingray is a small, common ray that lives close to shore along the Pacific coast of the Americas. It is best known on the beaches of southern California, where people are sometimes stung when they accidentally step on one. Its sting is painful but not fatal.1

Anaishi

Northeastern Pacific Ocean, from Humboldt Bay in northern California south to Panama. Most common around southern California and the Baja Peninsula.1

Nyumbani

It lives in warm coastal and bay waters, usually less than 15 m deep, over soft mud or sand, often among eelgrass. It also occurs around rocky reefs. People most often meet it on the beaches of southern California, especially the 'Ray Bay' at the northern end of Seal Beach, which is used as a nursery ground.1

Hula nini?

Round stingrays feed mostly on benthic invertebrates (animals living on the seabed). Juveniles eat polychaete worms and small benthic crabs, and adults shift towards bivalve molluscs. They dig large pits with their pectoral disc and mouth to uncover buried prey.1

Jinsi ya kumtambua

Nearly round pectoral fin disc, usually brown or grey-brown above with pale yellow spots or reticulations (a net-like pattern)1
Some individuals are plain or black1
Underside is white to yellowish1
Short, stout tail with a long, thick, serrated stinging spine1

Mara nyingi huchanganywa na: The Cortez round stingray (Urobatis maculatus) looks very similar and is sometimes sold under the same aquarium names. The round stingray can be told apart because it lacks the black spots on either side of its disc that the Cortez round stingray has.1

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

Every year, hundreds of beachgoers along the coast of southern California are accidentally stung by round stingrays. The stings are painful but non-fatal. The injuries usually happen when people step on the ray.1

Akidunga

Weka jeraha kwenye maji ya moto, moto kiasi ambacho mtu anaweza kuvumilia bila kuungua (pima kwanza kwa mkono wako), kwa dakika 30 hadi 90. Tafuta msaada wa kitabibu, hasa kwa samaki-jiwe na taa.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

The tail spine is shed and replaced regularly. For most of the year the ray has only one spine, but small secondary spines begin to appear in early July, and the replacement is complete by December.1

The species name honours a boy who was stung while wading in San Diego Bay.1

Females give off a weak electric field from near the spiracles behind each eye, which attracts males.1

Females can store sperm all year round.1

Their digging uncovers buried prey for smaller fish, which gives them an important role in the ecosystem.1
