Tripneustes gratilla, the collector urchin, is a species of sea urchin. Collector urchins are found at depths of 2 to 30 metres (7 to 100 ft) in the waters of the Indo-Pacific, Hawaii, the Red Sea, and The Bahamas. They can reach 10 to 15 centimetres (4 to 6 in) in size.

Egg jelly can vary in composition and complexity from the relatively homogenous single layer sea urchin egg to the three layer egg jelly in starfish. [5] There is an increasing concern in how ocean acidification will affect the fertilization of eggs. In H. tuberculate, low pH can damage the eggs chemical influence on sperm mobility and velocity ...
Tripneustes depressus is the largest sea urchin species in the Galápagos Islands with a mean diameter of 11.5 cm (4.5 in). The growth rate averages 0.5 mm (0.02 in) per month. [ 4 ] There is very little difference in morphology between T. depressus , Tripneustes gratilla and Tripneustes ventricosus ; they are suspected of being the same ...

Eucidaris tribuloides, the slate pencil urchin (named after slate pencil), is a species of cidaroid sea urchins that inhabits littoral regions of the Atlantic Ocean. As a member of the basal echinoid order Cidaroida , its morphological, developmental and molecular genetic characteristics make it a phylogenetically interesting species.
Sea urchin eggs are transparent and can be manipulated easily in the research laboratory. Their eggs can be easily fertilized and then develop rapidly and synchronously. [6] [7] For decades, the sea urchin embryo has been used to establish the chromosome theory of heredity, the description of centrosomes, parthenogenesis, and fertilization.
