After the founding of the Laboratory of Marine Biology in Qingdao, Tong studied the development of amphioxus during the 1950s and 1960s.
22.
Because in amphioxus, Nodal signaling pathway is on the left side of the embryo, which is the same situation as vertebrates.
23.
This would explain the bizarre embryology of Amphioxus, a basal cephalochordate widely held to be the prime example of a chordate bauplan.
24.
CYP19 is present in an early-diverging chordate, the cephalochordate amphioxus ( the Florida lancelet, " sponges, corals ).
25.
Amphioxus does not possess bone, making it an invertebrate, but it has common features with vertebrates including a segmented body and a notochord.
26.
He was the first to discover that the amphioxus was a separate taxa, and not the larvae of a mollusk, as previously thought.
27.
From his research of amphioxus, the anatomical terms-" Hatschek's pit " and " Hatschek's nephridium " are derived.
28.
If you look at " simpler " animals, ( for example, worms or the Amphioxus ) you can see how their primitive organs work.
29.
Tong and his colleagues used Nile Blue stain to color amphioxus embryos and to track the blastomeres in different stages of development up to 32-cell-embryos.
30.
According to Newman, Balanoglossus thus retains throughout life a larval organisation while Amphioxus and vertebrates have secondarily introduced metamerism by division of posterior coelom into a long scries of segments.
