Lancelets are also known as amphioxus. An example sentence would be: When prepared properly, he thinks lancelets are absolutely delicious.

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.
adult tunicate
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.
A lancelet is a filter feeder with no brain, eyes, or heart. A sea squirt is an example of a lancelet.
Yes. Lancelets are fish and all fish are ectothermic.
chordates
Chordates such as the sea squirts and lancelets do not have a backbone that is why they are called vertebrate chordates.
yes
By contracting muscles in their body.
Acoelomate
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.
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.
They're filter feeders
bony jaws
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.
