Etymology: Telatrygon: Name from Latin 'telum' for javelin, spear, arrow, dart and Greek 'trygon' for stingray; referring to the long, narrowly pointed snout possessed by all members of the genus.. More on authors: Müller & Henle.

Maturity: Lm 18.7, range 19 - ? cm
Max length : 29.0 cm WD maschio/sesso non determinato; (Ref. 9840); common length : 18.0 cm WD maschio/sesso non determinato; (Ref. 4832)
Common in estuaries (Ref. 4832). Feed on bottom-dwelling organisms (Ref.50449)- primarily small crustaceans, but also small fishes (Ref.58048). Ovoviviparous (Ref. 50449). Landed in very large quantities as by-catch in the bottom trawl and trammel fisheries. Utilized for its meat, but of limited value due to its very small size (Ref.58048).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialized structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). Gives birth to litters of 1-4 pups; born at 7-10 cm WD. No reproductive synchronicity (Ref.58048).
