Species Name: Carinoma tremaphoros
Common Name: None
Synonymy: None
  1. TAXONOMY

    Kingdom Phylum/Division Class: Order: Family: Genus:
    Animalia Nemertea Anopla Paleonemertea Carinomidae Carinoma
  2. HABITAT AND DISTRIBUTION

    IRL Distribution

    C. tremaphoros is distributed throughout the Indian River Lagoon

  3. LIFE HISTORY AND POPULATION BIOLOGY

    Age, Size, Lifespan

    Maturation age of adult Carinoma tremaphoros, typically 4 cm in length (1.6 inches), is probably 6 mos.

    Abundance

    Adult Carinoma tremaphoros is considered common in the Indian River Lagoon, FL.

    Reproduction

    Carinoma tremaphoros displays a gonochoristic mode of sexuality, with external outcross fertilization. It likely has one reproductive cycle per year, which lasts approximately 2 months.

    Embryology

    Probable time for egg development in Carinoma tremaphoros is 2 days, while the larval period lasts several weeks.

  4. PHYSICAL TOLERANCES

    No information is available at this time

  5. COMMUNITY ECOLOGY

    Trophic Mode

    Larval stages of Carinoma tremaphoros are probably planktivorous. The adult trophic mode is carnivory and detritivory.

    Habitat

    Larval stage of Carinoma tremaphoros is planktonic. The adult burrows into upper 10 cm of fine sand and mud substrata. Epidermal muscles in Carinoma tremaphoros allow effective burrowing in this species without segmentation (Turbeville and Ruppert 1983).
