Ernogrammus zhirmunskii Eggs | Seven-lined Prickleback

These are the unusually shaped eggs of a seven-lined prickleback (Ernogrammus zhirmunskii), a small fish found in the Northwest Pacific and Sea of Japan. Each egg is around 2mm to 3mm in size, photographed here at a magnification of four times life-size. The eggs that have been successfully fertilized are distinguishable by the developing embryos. The egg at the lower left appears to be non-viable.
