Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous References (not structured): Dame, Richard F. 1996. Ecology of Marine Bivalves: An Ecosystem Approach. New York: CRC Press, Inc. |
Reproductive type (?) | Sexual References: Dame, Richard F. 1996. Ecology of Marine Bivalves: An Ecosystem Approach. New York: CRC Press, Inc. Comments: Members of this species are gonochoric, and fertilization occurs externally. |
Developmental trait (?) | Planktotrophy Spawning References: Dame, Richard F. 1996. Ecology of Marine Bivalves: An Ecosystem Approach. New York: CRC Press, Inc. Comments: The larva is a trochophore, and when it develops it becomes a veliger larvae. Both larval stages are planktonic and free-swimming |
Characteristic feeding method / Life stage (?) |
References (not structured): Dame, Richard F. 1996. Ecology of Marine Bivalves: An Ecosystem Approach. New York: CRC Press, Inc. Comments: The larva is a trochophore, and when it develops it becomes a veliger larvae. Both larval stages are planktonic and free-swimming |
Mobility / Life stage (?) |
Comments: Chama is an oyster-like bivalve that has developed a permanently attached mode of life. Its deeply conical right valve is cemented to some substrate. |
Salinity tolerance range (?) | Venice system: 7. Euhaline [30-40psu] References: Mienis H.K., Galili E. and Rapoport J., 1993. On the presence of the Indo-Pacific bivalve Chama pacifica in the Eastern Mediterranean (Mollusca, Bivalvia, Chamidae). Gloria Maris, 32(2): 13-18. Comments: Chamids are stenohaline nearshore inhabitants of rocky shores and coral reefs with a poor ability to withstand low salinity as that of estuarine regions. |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: Mienis H.K., Galili E. and Rapoport J., 1993. On the presence of the Indo-Pacific bivalve Chama pacifica in the Eastern Mediterranean (Mollusca, Bivalvia, Chamidae). Gloria Maris, 32(2): 13-18. Comments: The shells are usually heavily encrusted with epibiontic flora and fauna |
