The books say that camels can't swim. I really don't know if this is true.
Some humans can't swim:) Swifts and hummingbirds can't swim
While I'm here, the following refs just in...
Christiansen, P. 2000. Feeding mechanisms of the sauropod dinosaurs
_Brachiosaurus_, _Camarasaurus_, _Diplodocus_ and
_Dicraeosaurus_. _Historical Biology_ 14: 137-152.
Incidentally, the last issue of HB was a special volume on aquatic
tetrapods (papers presented at the 2nd Symposium on Secondary
Adaptation to Life in Water): includes Taylor on bone ballast (not
'ballastin' as it says in the title), Fernandez on Argentinian
ophthalmosaurian ichthyosaurs, Paramo-Fonseca on the mosasaur
_Yaguarasaurus_, and loads of stuff on cetaceans, pinnipeds,
desmostylians, sirenians and turtles. Speaking of turtles... has anyone
seen the photos of the new Vietnamese softshells? My god they're big.
The current ish of HB also has - -
Naples, V.L. and Martin, L.D. 2000. Evolution of hystricomorphy in
the Nimravidae (Carnivora; Barbourofelinae): evidence for complex
character convergence with rodents. _Historical Biology_ 14: 169-
!!!!!!!!! Look fwd to reading it.
Woolley, J.D. 2000. The functional morphology of the avian flight
muscle m. coracobrachialis posterior. _The Journal of Experimental
Biology_ 203: 1767-1776.
Like many other papers on avian wing morphology, puts the structures
in their appropriate historical framework. Also some really interesting
perspectives on muscle isometry and neural modulation as provided by
case studies on turkeys, wallabies and cockroaches (!)
Farmer, C.G. and Carrier, D.R. 2000. Pelvic aspiration in the
American alligator (_Alligator mississipiensis_). _The Journal of
Experimental Biology_ 203: 1679-1687.
As above, puts alligator lung ventilaton and diaphragm function in
historical context and should be read alongside Carrier and Farmer
(2000 - _Paleobiology_ 26: 271-293, discussed previously on DML
by Tom Holtz). Carrier and Farmer cite an _American Zoologist_
article on this subject that's in press. There was a paper in the same ish
on alligator respiration, unfortunately I seem to have left it at home.
Have just been looking at slides of a Brazilian millipede mass
migration. Seems to be unreported in the literature so we might write it
