, intrauterine cannibalism and reproductive strategy in lamnoid sharks.
Like other members of the order Lamniformes, the bigeye thresher is an aplacental, viviparous species with intrauterine oophagy
, bearing 2-4 pups per litter, resulting in an extremely low fecundity (Moreno and Moron, 1992; Gilmore, 1993; Chen et al.
For example, these include notes on oophagy
by eels, consumption of eel leptocephali by bluefish, and taxonomy of Cyprinodon.

Reproduction, oviposition-site selection, and tadpole oophagy
of an arboreal nester, Chirixalus eiffingeri (Rhacophoridae), from Taiwan.
This unusual process is called oophagy
(from the Greek oion, meaning egg and phagy eat.
There are also two kinds of direct development: direct development in which large juveniles develop from large eggs (30% of species) and direct development with adelphophagy or oophagy
(15% of species) (Collin, 2003; Collin and Spangler, 2012).
As in other lamnids, young are nourished through oophagy
in stream-breeding California newts (Taricha torosa).
by tadpoles cannot explain this pattern, based on feeding observations in the laboratory.
Gilmore (1993) reviewed the reproductive biology of lamnoid sharks and included a redrawn sketch of the Sanzo (1912) embryo, still identified as a white shark, and also incorrectly stated that Sanzo (1912) had documented oophagy
for the white shark.
