Description: Note that all three embryo illustrations are shown in side view. The fish embryo is long, narrow and straight. Its head is small, round, and contains gill arches. A large flap extends to ...

Dr. Matan Golan of the Hebrew University of Jerusalem and the Agricultural Research Organization—Volcani Institute led a team of researchers who uncovered how fish embryos determine the ideal ...

The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish&apos;s embryos enter a state of extreme suspended animation or &apos ...

Zebra fish are useful research creatures because they develop externally, are transparent, and are available in large numbers. One pair of zebra fish can generate up to 200 embryos per week.

When Gagnon and his colleagues exposed embryos and larvae to UV light, embryos of mothers lacking the eevs gene failed to develop and only 2 per cent of their already hatched larvae survived.

When the waters dry out, the adult fish die, while the embryos remain dormant in the dry mud by entering diapause. Once the rain falls, the embryo’s development continues.

The researchers discovered that fish embryos initiate hatching through a signal from their brain: a neurohormone called Thyrotropin-Releasing Hormone (TRH).
