It belongs to the Phylum Ctenophora. • Pleurobrachia and Ctenoplana are CTENOPHORES. Here it passes the development stages which are very similar to those of the young Pleurobrachia. Hemichordata was earlier considered as a sub-phylum under phylum Chordata. Examples: Pleurobrachia and Ctenoplana. As this comb jelly waits for its prey to be caught in its tentacles, we are reminded to let life come to us. It possesses setae and parapodia for locomotion. The Pleurobachia bachei genome has been fully mapped and the scientist are studying which genes are activated to support remarkable regenerative properties that also include a regenerative brain and basic nervous system! P. bachei could very well hold the secrets to a cure for degenerative brain diseases such as Parkinsons disease and Alzheimers disease.  The humble Pleurobrachia bachei is also known as a Comb jellyfish.

Explanation Sponges are pore bearing animals belong to phylum porifera. This phylum consists of a small group of worm-like marine animals with organ-system level of organisation. When prey is caught in P. bachei’s tentacles it does not immediately consume the prey; it discerns the vulnerability of its prey and any danger a particular prey species may pose to P. bachei’s body.

Ans: Bioluminescence (the property of a living organism to emit light) is well- marked in ctenophores. Pleurobrachia; Bioluminescence is well marked property of pleurobrachia; Question 20. It belongs to the Phylum Ctenophora. Have trilocular heart. (B) A phylogenetic tree based on the N-J method shows clearly that Pleurobrachia Tlx belongs to the Tlx subfamily with Lbx and Nk2 genes as outgroups. 4, 2013 - Explore Nicholas Capitini 's board `` phylum Cnidaria '' on Pinterest as the oscillate.
