Species turbinata


  • Female: 1.05-1.61 mm
  • Male: 0.93-1.56 mm

Distinguishing characteristics

  • Cephalosome is typically widest and deepest part of the prosome, vaulted
  • 2 slender rostral filaments
  • Pedigerous segments 4-5 fused
  • P5 of female small, uniramous, 3-segmented; last segment dentate
  • P5 male asymmetrical, left leg larger and 4-segmented, segment 2 produced on inner edge into a long curved thumb-like process, right P5 3-segmented, terminal segment curved inwards, claw-like
  • Female urosome short, hardly protrudes ventrally
  • Very long caudal rami, may be asymmetrical


  • 'Teardrop' shaped cephalosome
  • A1 right geniculate
  • P5 left terminal segment relatively long and broad
  • Urosome somite 4 is longer than the anal somite
  • Caudal rami are longer than urosome


  • 'Teardrop' shaped cephalosome
  • Swimming legs compact
  • P5 with the inner spine on the terminal segment considerably shorter and thinner than the 2 terminal spines
  • Caudal rami are longer than urosome
  • Terminal seta 2 of the caudal rami is thick and asymmetrical

(Bradford Grieve 1999)


  • Epipelagic-mesopelagic
  • Widely distributed in the tropical, subtropical and temperate parts of the Indian Ocean and the Indo-Westpacific area
  • In the Indian and Pacific Oceans it goes about as far south as 35°S; in the Pacific Ocean it goes as far north as 40°N.  In the Atlantic the distribution is more or less erratic
  • Widespread and common in Australian waters


  • Undergo diel vertical migration
  • Isochronal development
  • Omnivorous, but primarily opportunistic herbivores
