The bat ray is a flat, diamond-shaped fish related to sharks, with wing-like fins that it flaps to swim. It lives in shallow coastal waters from central Oregon in the USA down to the Gulf of California in Mexico, and around the Galápagos Islands. It has a venomous spine near the base of its tail, but it uses it only when it feels threatened.1

Domov

Bat rays live in muddy or sandy sloughs, estuaries and bays, kelp beds, and rocky-bottomed shorelines. They are often found in flat, shallow water with sand patches between rocks. People can meet them in shallow sand, so walking there calls for care.1

Kaj je?

Bat rays eat molluscs, crustaceans and small fish from the seabed. They use their wing-like fins to move sand and expose prey, and may dig pits up to 20 cm deep with their snouts to reach buried clams. Their flat, pavement-like teeth crush shells, and the hard pieces are spat out while the soft parts are swallowed.1

Če piči

Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel (preizkusi jo s svojo roko), za 30 do 90 minut. Poišči zdravniško pomoč, še posebej pri kamnitih ribah in morskih bičih.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

Bat rays dig pits in the seabed that can be up to 4 m long, and small fish gather to eat the creatures the rays expose.1

The bat ray's young are born with the spine's sheath, which falls off within hours of birth.1

Bat rays can grow to a wingspan of 1.8 m, and the largest individuals weigh about 91 kg.1

Some bat rays live alone, while others form schools of thousands.1

Bat rays have teeth that are replaced continuously, as is the case with all elasmobranchs (sharks, rays and their relatives).1

Razbijalec mitov

Mit: Bat rays are dangerous to people because of their venomous spine.

Resnica: Bat rays are not considered dangerous. They use the spine only when attacked or frightened, and people can avoid it by shuffling their feet when walking through shallow sand.1
