- Salient Features and Classification of Non-chordates Phylum - Coelenterata (Cnidaria), Phylum - Arthropoda The reproductive processes of two organisms were studied. In Animal I, the offspring generated from a detached part of its body, preferably the tail and in Animal Il the offspring was obtained directly from the ovum without fertilization. Thus, on the basis of the information obtained, the animals can be categorized as (a) Hydra and Bee, respectively (b) Planaria and Aphid, respectively (c) Hydra and Aphid, respectively (d) Both (A) and (B)Amphioxus gastrulation results in __________ layered sac. The opening of the sac is the ___________; the cavity within the archenteron or __________.Which of the following characteristics is not seen in the phylum Platyhelminthes?a. cephalizationb. the presence of a mesodermc. specialization of the digestive tractd. bilateral symmetry
