The lancelets — also known as amphioxi(singular, amphioxus) consist of about 32 species of fish-like marine chordates in the order Amphioxiformes. They are distributed in shallow and coastal temperate  as Norway, subtropical and tropical seas around the world, usually found half-buried in sand. The only exception is Asymmetron inferum, a species known from the vicinity of whale falls at a depth of about 225 m.

In lancelets and ascidians (sea squirts), endostyle is a part of the digestive system that aids in filter feeding.

  • Endostyle is a glandular organ lying below the two rows of gill slits in lower-chordates.
  • It filters suspended food particles from the water as it coats itself with mucus using cilia.
  • The mucus sticks to the food particles suspended in the water which is then passed through the pharynx and then to the esophagus  by the ciliary movements.

Note: As the endostyle absorbs iodine, an evolutionary link has been suggested between this organ and the thyroid gland of vertebrates.
