Which structure S represents a key innovation that arose during all vertebrate diversification?
Which structure represents a key innovation that arose during vertebrate diversification? Amniotic egg. The amniotic egg is an innovation that occurred during vertebrate diversification, which allowed vertebrates to reproduce on land.
Do all deuterostomes have a Coelom?
The coelom (a fluid-filled body cavity lined with mesoderm) develops from buds off the embryonic gut. A number of deuterostomes have distinctive larval forms. The Deuterostomia constitute one of two divisions of the coelomates (animals having a coelom). Compare Protostomia.
Which of the following are all deuterostomes?
The major groups of living deuterostomes comprise three distinct clades. These are the echinoderms, which are the sea stars, sea urchins, and their relatives; hemichordates, which are acorn worms and pterobranchs; and chordates. The chordates include lancelets, sea squirts and other tunicates, and vertebrates.
Are all deuterostomes triploblastic?
They are a sister-clade of the Protostomes, and the two together with the Xenacoelomorpha form the major group of animals called the Bilateria—a major group animals which display bilateral symmetry and are mostly triploblastic.
What trait's characterizes the vertebrates?
Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Which of the following are chordates not vertebrates?
From the given organisms, the Amphioxus is a chordate but not a vertebrate. Amphioxus, commonly known as lancelet, is a marine fish like chordate that possesses a dorsal nerve cord which is not protected by bone but by a simple notochord made up of a cylindrical cell pattern, closely packed to form a toughened rod.
Which of the following are the most abundant and diverse of the extant vertebrates?
The bony fish (A) is the most abundant and diverse of the extant vertebrates. The members of the bony fish, actinopterygians, dominate the vertebrates and the fishes species in total. Actinopterygii is also known as ray finned fish.
Which phylum do not belongs to deuterostome?
Earthworm is not a deuterostome. Deuterostomes are distinguished by their embryonic development.
Are mollusks deuterostomes?
Molluscans are protostomes.
Their mouth arise from the embryonic blastopore. ... The blastopore becomes mouth in protostomes (i.e. mouth appeared first) while in deuterostomes it forms anus (i.e. mouth appears later).
Are vertebrates Protostomes or deuterostomes?
The majority of animals more complex than jellyfish and other Cnidarians are split into two groups, the protostomes and deuterostomes. Chordates (which include all the vertebrates) are deuterostomes.
What do vertebrates and tunicates share?
Q: Vertebrates and tunicates share
a notochord and a dorsal, hollow nerve cord. the formation of structures from the neural crest.
Are amphibians Triploblastic?
Presence of paired pharyngeal gill slits. They are bilaterally symmetrical. They are Triploblastic animals. They have true coelom so known as coelomate with well- developed organ system and organization.
Are sponges deuterostomes?
Simple animals do not have a body cavity – but higher animals, like mammals do. Protostome coelomates include the mollusks, annelids and arthropods, whereas deuterostome coelomates include the echinoderms and chordates. ... In mammals, […] Porifera, the sponges, and cnidaria, the jellies and kin, are actually neither.
