Abstract
Acetaminophen, or paracetamol is an overβtheβcounter analgesic generally used by all groups of people, including pregnant women. The present investigation aims to elucidate the effects of acetaminophen on the development of zebrafish Danio rerio in which embryogenesis is ex utero. Developing eggs (n = 30) were exposed to different doses (0, 1, 5, 10, 50 and 100Β Β΅g L^β1^) of the drug in triplicate and observations were made hourly until gastrulation and once in 24Β h thereafter for seven consecutive days. Acetaminophen induced anomalies at different levels of development in a doseβdependent manner, causing impairment in (1) the early development, (2) hatching, (3) organogenesis (by altering the rate of apoptosis), (4) larval growth and morphometry, (5) tail and tailβfin formation, (6) pigmentation and (7) larval behavior and survival. The results of the present study clearly reveal that acetaminophen interfered with the normal embryonic development, growth, behavior and survival of D. rerio larvae.

## Abstract The study was designed to test the hypothesis that male aging is associated with a change in reproductive function in the zebrafish. Young (290 Β± 37 d) and older (911 Β± 48 d) males were combined with females (604 Β± 24 d) to test the effect of male age on the number and fertility of eggs
It has been suggested that stimulus dependence is a general feature of all developing sensory systems. We tested this idea for the developing zebrafish vestibular system using a bioreactor the National Aeronautic and Space Agency designed to simulate microgravity for cells in culture on earth. We re
