The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if they must withstand physical force or desiccation. These type of eggs can also be very small and ...
The butter on bread may soften the taste of large pellets of black or red roe this way, by making it more dull, and the bread should be soft and fresh rather than soggy, crisp or bun-like dense. More common roes, such as cod , Alaska pollock , and herring ones are everyday dishes, combining richness in protein with low price.

Seahorses and pipefish can be defined as livebearers, although in these cases the males incubate the eggs rather than the females. In many cases, the eggs are dependent on the male for oxygen and nutrition so these fish can be further defined as viviparous livebearers. [citation needed] Many cichlids are mouthbrooders, with the female (or more ...
Fish eggs cannot swim at all, and are unambiguously planktonic. Early stage larvae swim poorly, but later stage larvae swim better and cease to be planktonic as they grow into juvenile fish . Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply.
Parthenogenesis (/ ˌ p ɑːr θ ɪ n oʊ ˈ dʒ ɛ n ɪ s ɪ s,-θ ɪ n ə-/; [1] [2] from the Greek παρθένος, parthénos, 'virgin' + γένεσις, génesis, 'creation' [3]) is a natural form of asexual reproduction in which the embryo develops directly from an egg without need for fertilization.
