The Zoology of the Voyage of H.M.S. Samarang, under the command of Captain Sir Edward Belcher, C.B., F.R.A.S., F.G.S., during the years 1843-1846 - London: Reeve and Benham,1850
HMS Samarang was a 28-gun, teak, sixth rate of the Royal Navy. She was launched at Cochin in 1822 by the East India Company.
She served in various stations around the world until seeing action in the First Opium War, and was then employed, under Edward Belcher, in surveying the coast of Borneo from 1843-1846, after which she became a guardship at Gibraltar before being sold for breaking in 1883

I found an old lab notebook, from my Chordate Evolutionary Biology class. I was actually not awful at drawing skeletons, it seems.
Quick pen and marker study of the spider I just found yesterday. Looked at him under my stereo microscope for a few hours and got some good studies in for future artworks. I’ll touch this up more tomorrow when I’m more awake. I just let him go outside, thanks dude!
Sorry teacher for my Tardegrades…
-some doodles in ballpoint pen I did of cool little micro organisms called waterbears (or tardegrades). Google or YouTube for videos of them. They way they ‘walk’ is kind of cute :)
The developmental stages of scyphozoan jellyfish’s life cycle:
1–3 Larva searches for site
4–8 Polyp grows
9–11 Polyp strobilates (strobilation is a form of asexual reproduction consisting of spontaneous transverse segmentation of the body.)
12–14 Medusa (adult jellyfish) grows.
Another unusual species, T. nutricula, falsely reported as Turritopsis dohrnii, might be effectively immortal because of its ability under certain circumstances in the laboratory to transform from medusa back to the polyp stage, thereby escaping the death that typically awaits medusae post-reproduction if they have not otherwise been eaten by some other ocean organism . So far this transdifferentian of life form has been observed only in the laboratory and it is not known if it actually occurs in wild Turritopsis populations.
