Ijima's sea snake, Ijima's turtleheaded sea snake
Emydocephalus ijimae, also called Ijima's sea snake and Ijima's turtleheaded sea snake, is a species of snake in the family Elapidae. The species is endemic to East Asia. E. ijimae feeds exclusively on the eggs of coral reef fishes, which makes them an important predator for maintaining a healthy coral reef ecosystem.
The specific name, ijimae, is in honor of Japanese zoologist Isao Ijima (1861–1921).
E. ijimae is viviparous. Neonates begin reproductive activity in the second or third summer and third spring after birth. Studies have suggested that E. ijimae are income breeders that rely on temporal energy intake to produce offspring.
