How To Use Urochorda In A Sentence
- We chordates are deuterostomes, as are echinoderms, some marine worms called hemichordates, and the urochordates, or sea squirts.
- In particular, there is a significant phylogenetic gap in information for the urochordates, a subphylum near the invertebrate-vertebrate transition.
- Their report that urochordates are comprised of 4 discrete lineages holds interesting implications for understanding the evolution of tadpole morphology and chordate life history.
- These data further support the hypothesis that duplication and differentiation giving rise to cardiac and skeletal genes occurred following divergence of the urochordate and vertebrate ancestors.
- For instance, adult urochordates are typically sessile, while many vertebrates are quite active.
- The phylogenic analysis implies that the multiple actinin isoforms found in modern vertebrates arose after the divergence of the vertebrate and urochordate lineages.
- The authors added many new hemichordate and urochordate taxa to the database and found strongly supported relationships among the major deuterostome groups.
- A chordate marine animal of the subphylum Urochordata; a tunicate.
- The urochordates or tunicates are sessile (attached to the bottom) marine filter-feeders, and rather sponge-like as adults.
- This suggests that the disruption observed is specific to the urochordate lineage.
