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.
Eponymy: This species’ binomial zugei is after zugu-ei, the Japanese name for this species. (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; demersal; amphidromous (Ref. 51243)(Ref. 114953). Tropical
Northwest Pacific: Vietnam to Japan, probably in the Philipinnes and Thailand.
Length at first maturity / Size / Weight / Age
Maturity: Lm 18.7, range 19 - ? cm
Max length : 29.0 cm WD male/unsexed; (Ref. 109651)
Feed on bottom-dwelling organisms (Ref.50449); primarily small crustaceans, but also small fishes (Ref.58048). Ovoviviparous (Ref. 50449).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).
