Abstract
Embroyonic development in snail is a dynamic process that includes the
transformation of fertilized ovum into miniature shelled organism in a confined
transparent egg capsule. The just layed egg was observed with uncleaved zygote
containing yolk, animal pole, the vegetal pole, and no polar body was present. The
first polar body was observed just after laying 30 minutes, which on later
followed by the first cleavage division about 120-130 minutes approximately, leading
to form 2-cell stage. The embryonic cell divided was followed with the
formation of gastrula, trochophore, veliger and before hatching miniature
shelled snail was clearly visible, the complete process of embryonic
development took 11-12 days, observed in the laboratory in the fresh water
snail L. acuminata.
