Which of the following animals is most closely related to the hagfish?

Molecular analysis since 1992 has suggested that hagfish are most closely related to lampreys and so also are vertebrates in a monophyletic sense. Others consider them a sister group of vertebrates in the common taxon of craniata.

Which of the successful and diverse animal phyla are the chordates most closely related to?

Echinoderms are the most closely related phylum to the phylum Chordata which includes many complex organisms such as humans.

Which of the following is a defining characteristic of animals?

All animals are eukaryotic multicellular organisms and almost all animals have specialized tissues. Most animals are motile at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic ingesting living or dead organic matter.

Which phylum is most closely related to the arthropods?

Are lampreys and hagfish related?

Yes. Lamprey and hagfish are both jawless fishes. They are the only living members of the taxonomical class Agnatha (Greek for “no jaws”).

What are the hagfish predators?

They have a defence that makes them all but untouchable. Their only predators are either very large fish whose gills are too big to clog or mammals which don’t have gills and whose stomachs can easily digest or expel the slime.

Why do scientists think that echinoderms and chordates are closely related?

Why do scientists think that echinoderms and chordates are closely related even though they are structurally so different from one another? They are both deuterostomes. What are the defining characteristics of echinoderms? How have the body structures of sea lilies and feather stars adapted to a sessile lifestyle?

Which phylum includes animals that lack tissues?

Sponges: The Phylum Porifera | Back to Top. The phylum Porifera (“pore-bearing”) consists of approximately 5 000 species of sponges. These asymmetrical animals have sac-like bodies that lack tissues and are usually interpreted as representing the cellular level of evolution.

What do echinoderms and chordates have in common?

Which of the following is common in annelids and arthropods?

Both Annelida and Arthropoda share many features. Both are triploblastic animals with bilateral symmetry. Both consist of a segmented body. Both Annelida and Arthropoda consist of a hydrostatic skeleton.

How are echinoderms and arthropods alike?

Are arthropod and echinoderm skeletons similar? Arthropod and echinoderm skeletons are very similar. Sea stars can stick their stomachs out through their mouths to aid feeding. Early embryological features such as the fate of the blastopore can be the basis for major divisions in categorizing animals.

What do lampreys and hagfish have in common?

Lampreys and hagfishes have gill pouches for ventilation connected to the external environment by numerous holes or slits on the sides of the body and back of the head. These animals have a simple cartilaginous skeleton.

What are the differences between hagfish and lampreys?

Hagfish is an eel-like slime producing marine jawless fish while lamprey is an eel-like jawless fish that lives in coastal and freshwaters. Hagfish does not possess vertebra while lamprey has vertebra. Hence hagfish is not considered as a vertebrate while lamprey is a vertebrate.

Do hagfish have scales?

Hagfishes have no fins or scales—flat rigid plates that act as body covering. They do not have jaws but have two raspy or rough biting plates.

Do hagfish have gills?

Hagfish take in water through their nasopharyngeal duct which leads to their pharynx and gill pouches. Different species have between 5 and 15 pairs of gills. Hagfish also have a well-developed network of capillaries in their skin which might allow them to “breathe” through their skin when buried in mud.

Are hagfish carnivores?

How are chordates and vertebrates related?

As chordates vertebrates have the same common features: a notochord a dorsal hollow nerve cord pharyngeal slits and a post-anal tail. Vertebrates are further differentiated from chordates by their vertebral column which forms when their notochord develops into the column of bony vertebrae separated by discs.

Why are echinoderms considered to be closely related to chordates than any other phylum?

Why are echinoderms more closely related to chordates than to other animal phyla?

How do you determine the phylum of an animal?

At its most basic a phylum can be defined in two ways: as a group of organisms with a certain degree of morphological or developmental similarity (the phenetic definition) or a group of organisms with a certain degree of evolutionary relatedness (the phylogenetic definition).

What do echinoderms have in common?

All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore these appendages usually occur in multiples of five although there are a few exceptions.

Do echinoderms have scales?

They do not have gills scales or fins. Sea stars live only in saltwater. … Sea stars are related to sand dollars sea urchins and sea cucumbers all of which are echinoderms meaning that they have five-point radial symmetry.

  • They are exclusively marine animals.
  • The organisms are spiny-skinned.
  • They exhibit organ system level of organization. …
  • They are triploblastic and have a coelomic cavity.
  • The skeleton is made up of calcium carbonate.
