ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Occurs in seagrass areas, rocky reefs, and adjacent soft bottoms (Ref. 12951). Avoids temperatures above 20°C (Ref. 10011). Nocturnal, usually burying itself during the day with only the eyes and spiracle jutting out (Ref. 12382). Feeds on small benthic fishes Trachurus, Mugil, Mullus, Dicentrarchus, Spondyliosoma, Boops, Labrus, Dascyllus, Pomacentrus) and crustaceans (Ref. 10011). Females outlive males; viviparous, neonates measuring 10-14 cm at birth (Ref. 10426). Produces 2-32 pups in a litter after a 10-month gestation (Ref. 12951, Ref. 114953). Males reaches maturity at ca. 30 cm TL, females at ca. 40 cm TL; born at 10-14 cm TL (Ref. 114953). Electrocytes start developing when the embryo weighs about 1 g; electric organs functional before birth and newborns can use their electric organ discharge (EOD) in capturing prey (Ref. 10428). Can produce electric discharges of up to 200 volts; EOD frequency up to 600 Hz. Jumps on fast-moving prey, paralyzing it with its EOD (Ref. 27000).

Life cycle and mating behavior Maturities | ການສືບພັນ | Spawnings | Egg(s) | Fecundities | ຕົວອ່ອນ

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 specialised structures (Ref. 50449).
