Table 1 Development times of Temnopleurus toreumaticus and T. reevesii at 24°C

From: Development of the sea urchins Temnopleurus toreumaticus Leske, 1778 and Temnopleurus reevesii Gray, 1855 (Camarodonta: Temnopleuridae)

Developmental stages	Time after fertilization^a
Developmental stages	*T. toreumaticus*	*T. reevesii*
PMC ingression	10 h	9 h
Early gastrula stage	11 h	12 h
Prism stage	16 h	21 h
PPC formation	23 h	20 h
Initiation of CM formation	26 h	24.5 h
Two-armed pluteus stage	28 h	30 h
Four-armed pluteus stage	2 days	2 days
Six-armed pluteus stage	10 days	9 days
Adult rudiment formation	21 days	16 days
Eight-armed pluteus stage	25 days	26 days
Metamorphosis	31 days	33 days

^aWe defined each developmental stage as a stage observed in more than 80% of 50 specimens. After the six-armed pluteus stage, the values show the developmental time of more than 50% of the surviving specimens.
