How is an lancelet different then a fish?
A lancelet is ... The lancelets (subphylum Cephalochordata, traditionally known as amphioxus) are a group of primitive chordates. They are usually found buried in sand in shallow parts of temperate or tropical seas. In Asia, they are harvested commercially for food for humans and domesticated animals. They are an important object of study in zoology as they provide indications about the origins of the vertebrates. Lancelets serve as an intriguing comparison point for tracing how vertebrates have evolved and adapted. Although lancelets split from vertebrates more than 520 million years ago, its genome holds clues about evolution, particularly how vertebrates have employed old genes for new functions.[1] In the issue of Nature on 19 June 2008, the draft genome sequence of the Florida lancelet (Branchiostoma floridae) was reported.[2] -Wikipedia Yes, lancelets are animals, their supphylum is cephalochordata.
Which of the following chordates is most likely to look least like other chordates?
adult tunicate
List and Describe an examples of invertebrate chordata.?
One example of an invertebrate chordate is the lancelet (Branchiostoma). Lancelets are small, fish-like marine organisms that possess a notochord, a dorsal nerve cord, and pharyngeal slits. They lack a true vertebral column but exhibit key characteristics of chordates.
What is an example of Lancelets?
A lancelet is a filter feeder with no brain, eyes, or heart. A sea squirt is an example of a lancelet.
Are lancelets ectotherms?
Yes. Lancelets are fish and all fish are ectothermic.
What Tunicates and lancelets are two subphyla of animals classified as what?
chordates
What some chordates such as sea squirts and lancelets do not have?
Chordates such as the sea squirts and lancelets do not have a backbone that is why they are called vertebrate chordates.
Are lancelets filter feeders?
yes
How do lancelets move?
By contracting muscles in their body.
What type of body cavity do lancelets have?
Acoelomate
Do lancelets have a backbone?
No, lancelets do not have a backbone. They are small, fish-like marine invertebrates that belong to the subphylum Cephalochordata and possess a notochord instead of a true backbone.
Are lancelets dueterstome?
Yes, lancelets are deuterostomes. Deuterostomes are a group of animals characterized by their embryonic development, in which the blastopore becomes the anus. Lancelets belong to the phylum Chordata along with vertebrates, and they exhibit deuterostome development.
How do tunicates and lancelets get their food?
They're filter feeders
What is the difference between hagfish and lancelets?
bony jaws
Tunocates and lancelets are two subphyla of animals classified as what?
Tunicates and lancelets are two subphyla of animals that are classified as Chordata. This means that they have dorsal nerve cords as well as notochords.
