Yes. Lancelets are fish and all fish are ectothermic.
What else can I help you with?
Can you list ectotherms?
Reptiles (Lizards and Snakes) are ectotherms Amphibians are ectotherms
Are sea turtles endotherms or ectotherms?
Ectotherms their body temperature changes with the environment
Are amphibians endotherns or ectotherns?
Endotherms are warmblooded, ectotherms are coldblooded, so amphibians are ectotherms.
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
Are all insect ectotherms?
Yes. As a rule of thumb; all animals are ectotherms except for mammals and birds.
What type of body cavity do lancelets have?
Acoelomate
How do lancelets move?
By contracting muscles in their body.
Why do ectotherms hibernate?
ectotherms' body temperature change with surrounding climate. hence to avoid exposure to cool temperatures, they hibernate.
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.
