Tunicate A.K.A. Ciona intestinalis

More complex then they might come across!

Phylum, Subphylum

  • Member of the subphylum Tunicata, which is part of the phylum Chordata.

Siphons and Adaptations


  • A siphon is a tubular organ in an aquatic animal, especially a mollusk, through which water is drawn in or sent out.
  • When they start eating, these animals extend their bodies until they are fully extended.
  • After this their siphons are fully visible.
  • When resting, their siphons are retracted.
  • These work by taking in water and then extracting food particles from the water and using them as nutrients.

Adaptations


  • A siphon is a behavioral adaptation used for eating in aquatic animals.
  • For reproduction these animals reproductive organs mature at different times.
  • Because of this self fertilization will not happen
  • Reproduction will happen when they sense species specific sperm in the water and discharge the eggs (or sperm) through the exhalent siphon

Fun Facts!

  • Can help depollute waters because of the Siphons which extract particles from the water.
  • Despite the gelatin like body form, these animals are very closely related to vertebrates.
  • When they are young they have a notochord but adults loose it and become invertebrates.
