- Phytodetritus varies in colour and appearance and may be greenish, brown or grey, flocculent or gelatinous.
- Maximum numbers of bacteria generally occur at the pycnocline, where phytodetritus accumulates by sinking from the overlying euphotic zone.
- At the end of phytoplankton bloom, when the algae enter a senescent stage, there is an accumulation of phytodetritus and an increased release of dissolved metabolites.
- Then, they morph into the megalopa stage and settle to the ocean floor among the phytodetritus; the megalopa stage is the advanced larval stage that the crab develops into before becoming a true adult.
- Conclusions found that the miliolid Quinqueloculina sp . was virtually absent in multicore samples from 1989-1994, peaked in September 1996 ( 22 % ) when degraded phytodetritus was present on core surfaces, was less common in March 1997, and thereafter was relatively uncommon.
