Reproduction ( anglais )

fourni par EOL authors

Metridium is capable of both sexual and asexual reproduction. In sexual reproduction, the eggs and sperm are released into the water and form planula larvae after fertlization occurs (Hoffmann 1986). Individuals that live deeper and are continuously submerged are able to grow to larger sizes, which increases feeding efficiency and gamete production (Bucklin 1987). Sexual reproduction is more likely to occur in these individuals because of this.Asexual reproduction is acheived through pedal laceration, which produces clones of the individual (Hoffmann 1986). This is most common in intertidal individuals that cannot grow as large, possibly because of limited food and feeding time in addition to damage by wave action. Since these individuals can reproduce asexually, it allows for reproduction and growth despite their smaller body size (Bucklin 1987).
