Ostorhinchus capricornis Ostorhinchus capricornis Ostorhinchus capricornis, also known as the Capricorn cardinalfish, is a species of ray-finned fish, a cardinalfish from the family Apogonidae which occurs around reefs in the western Pacific Ocean. "Ostorhinchus capricornis" is dusky yellow in colour, this lightens to bronze or golden yellow on the ventral surfave. It has a black spot around the caudal peduncle and it has two "neon" blue stripes which run through the eye, the lower stripe extending to the posterior edge of the operculum. It grows to a maximum standard length of . It is similar to the yellow cardinalfish ("Ostorhinchus flavus") but
Caudal cell mass Caudal cell mass In humans and other mammals, the caudal cell mass (sometimes tail bud in humans) is the aggregate of undifferentiated cells at the caudal end on the spine.The caudal end of the spinal cord first begins to form after primary neuralation has taken place, indicating that it develops after the cranial portion of the spinal cord has developed. Following neuralation, the caudal tail begins to form a neurocele as it develops a hollow core. After this, secondary neuralation occurs in which the medullary cord begins to form and is filled with many cavities that ultimatelly form the lumen.
