Document Summary

Feature creature, the bone eating snot flower (cid:862)oseda(cid:454)(cid:863) The granules will move towards the membrane and release their content in perivitalline space. And this occurs when sperm makes contact: the membrane expands to block the other sperm from coming in, fertilization envelope is what expands. Internal fertilization: direct deposition, copulatory organ, meaning diffuses to deposit gametes into another, courting behaviours, tries to get females recepted. Indirect deposition: spermatophore (package of sperm and nutrients to keep sperm happy released into environment until female decides whether or not the package is worth while. If yes, then she will take it in: may or may not be involved with mating behaviours. Fertilized eggs: what to do with developing zygotes, 1. We call this matrotrophic viviparity: where they eat tissue of mother, whe(cid:374) the(cid:455)(cid:859)re old e(cid:374)ough, is (cid:449)he(cid:374) the sharks will be released, most investment/energy to put in but embryo has much better surviving.
