Check Out this Awesome Channel: http://bit.ly/fnfonyt • This is the Lab Specimen of Lancelet [Branchiostoma lanceolatum (AKA Branchiostomiformes)] preserved in Formalin. • FYI: The Lancelet — also known as Amphioxus consist of about 32 species of fish-like marine chordates in the order Amphioxiformes, with a global distribution in shallow temperate and tropical seas, usually found half-buried in sand. • They are the modern representatives of the subphylum Cephalochordata, formerly thought to be the sister group of the Craniates. • They are an important object of study in Zoology as they provide indications about the evolutionary 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, their genomes hold clues about evolution, particularly how vertebrates have employed old genes for new functions. • Anatomy: Lancelets are typically 5 centimetres (2.0 in) long. They have a translucent, somewhat fish-like body, but without any paired fins or other limbs. A relatively poorly developed tail fin is present, so they are not especially good swimmers. While they do possess some cartilage-like material stiffening the gill slits, mouth, and tail, they have no true skeleton. • SCIENTIFIC CLASSIFICATION: • Kingdom: Animalia • Phylum: Chordata • Subphylum: Cephalochordata • Class: Leptocardii • Order: Amphioxiformes • Families: Asymmetronidae (or Branchiostomidae) • Please Like, Comment Share the video so that more more people can view it. • And As Always, THANKS FOR VISITING..:-) • Share, Support, Subscribe!!! • Join the #FnFPicks Community: • YouTube: http://bit.ly/fnfonyt • Facebook: http://bit.ly/fnfonfb • Twitter: http://bit.ly/fnfontwt • Instagram: http://bit.ly/fnfonig • Blogger: http://bit.ly/fnfblog • And don't forget to Subscribe...:-)
