D. strigosa reproduces sexually by a process called gametogenisis. They can also reproduce asexually by fragmentation. Moreover, they are hermaphrodites they are able to produce both male and female gametes. "D. strigosa uses the broadcast spawning method of fertilization; this is when the sperm and eggs combine in the water column or at the surface as opposed to brooding where fertilization occurs within the maternal polyp" (Evans, Wood, and Zeeh). Studies have shown that D. strigosas' spawning season occurs for a short time in mid August and spawning mainly occurs at night. Temperatures for peak fertilization are between 25 to 29 degrees Celsius and if the temperatures rise over 30 degrees Celsius larval developmental problems begin to occur" (Evans).
