coenosarc การใช้

ประโยคมือถือ
  • A few soft corals are stolonate, but the polyps of most are connected by sheets of coenosarc.
  • The polyps are 1 millimetre ( 0.04 in ) in diameter and the coenosarc covering the skeleton is thin.
  • As long as the colony is alive, the polyps and coenosarc deposit further calcium carbonate under the coenosarc, thus deepening the corallites.
  • As long as the colony is alive, the polyps and coenosarc deposit further calcium carbonate under the coenosarc, thus deepening the corallites.
  • It involves the growth of the coenosarc to seal off the polyps, detachment of the polyps and their settlement on the seabed to initiate new colonies.
  • The distance between the new and adult polyps grows, and with it, the coenosarc ( the common body of the colony; see coral anatomy ).
  • It is also likely to benefit from some diffusion of nutrients from the coenosarc ( living tissue ) of the coral which overgrows it, another reason for considering it parasitic.
  • The gonophores in the family Solanderidae where known, arise directly from "'coenosarc "'( i . e . the hollow living tubes of the upright branching individuals of a colony ).
  • In other species, small balls of tissue detach themselves from the coenosarc, differentiate into polyps and start secreting calcium carbonate to form new colonies, and in " Pocillopora damicornis ", unfertilised eggs can develop into viable larvae.
  • The gonophores in the family Milleporidae arise from the coenosarc ( the hollow living tubes of the upright branching individuals of a colony ) within chambers embedded entirely in the coenosteum ( the calcareous mass forming the skeleton of a compound coral ).
  • For example, some carpenter bees will form colonies when a dominance hierarchy is formed between two or more nest foundresses ( facultative colony ), while corals are animals that are physically connected by living tissue ( the coenosarc ) that contains a shared gastrovascular cavity.
  • This has been termed " polyp bail-out " and involves growth of the coenosarc ( the living tissue covering the skeleton ) to isolate the polyp, detachment of the polyp, and settlement of the polyp on the seabed followed by its attachment and growth of a new skeleton.
  • The colony grows by budding, and in favourable conditions, the clump can grow at the rate of one new polyp every three days . In colder conditions it may stop growing and the coenosarc ( soft tissues ) may die back to some extent, rendering the stony skeleton prone to being fouled by other organisms.
