Length at first maturity / Size / Weight / سن
بلوغ: Lm ? range ? - ? cm
The species has a slender, cylindrical body made up of many identical segments with simple, bilobed parapodia, which rarely grows longer than a few centimeters. The head has no appendages and is rounded to oval. It has an eversible proboscis covered with jaws. It is pink, orange, or brown in color.
This species probably has a non-pelagic development because of its jaw, thus tagged as a predator like most other lumbrinerids (Ref. 76547). Either a carnivore or omnivore (Ref. 108299).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | Eggs | Fecundity | Larvae
Members of the class Polychaeta are mostly gonochoric (sexual). Mating: Females produce a pheromone attracting and signalling the males to shed sperm which in turn stimulates females to shed eggs, this behavior is known as swarming. Gametes are spawned through the metanephridia or body wall rupturing (termed as "epitoky", wherein a pelagic, reproductive individual, "epitoke", is formed from a benthic, nonreproductive individual, "atoke"). After fertilization, most eggs become planktonic; although some are retained in the worm tubes or burrowed in jelly masses attached to the tubes (egg brooders). Life Cycle: Eggs develop into trocophore larva, which later metamorph into juvenile stage (body lengthened), and later develop into adults.
