What type of feeders are Chordata?

Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets), together with the vertebrates in Vertebrata. Most tunicates live on the ocean floor and are suspension feeders. Lancelets are suspension feeders that feed on phytoplankton and other microorganisms.

Are Chordata carnivores?

Why chordates are most advanced?

Chordates have their skeletons on the inside, a design that allows for growth without the need for molting. … Three features are present in all chordates. These include a stiffening rod, called a notochord that in many members (e.g., the vertebrates) is replaced during development by a bony, vertebral column.

Are chordates the same as vertebrates?

Chordates are characterized by the presence of a notochord. … The main difference between chordates and vertebrates is that some chordates do not have a vertebral column whereas all vertebrates have a vertebral column. In vertebrates, the vertebral column surrounds and protects the nerve cord.

How do chordates survive?

It keeps the animal from shortening when locomotory waves are produced through muscular contraction. The chordate body is supported by fluid in the body cavities. In tunicates, added support is provided by the tunic. Cartilaginous material supports the gills and other body parts of tunicates and cephalochordates.
