Stereotropic Reactions of the Shovel-nosed Ray, Rhinobatus Productus
I t has been pointed out by Loeb 1 that our orientation in space is determined mainly by three groups of tropistic influences; namely, light, gravitation, and contact. Light and gravitation cause the orientation of organisms through effects upon muscle tonus. When the lines of force strike the animal obliquely, as for example, when light rays fall unequally on 1:he two eyes, the unequal stimula...
متن کاملPhyllosomas of smooth fan lobsters (Ibacus novemdentatus) encase jellyfish cnidae in peritrophic membranes in their feces
Jellyfish possess venomous cnidae on their tentacles to capture and consume marine zooplankton. Nevertheless, the planktonic larvae of the smooth fan lobster (Ibacus novemdentatus), known as phyllosoma, prey on jellyfish and successfully ingest both tentacle tissue as well as constituent cnidae, despite the presence of the venom-filled explosively penetrant cnidae or nematocysts. In the present...
متن کاملAdditional slipper lobsters of the subfamily Scyllarinae Latreille, 1825 (Crustacea, Achelata, Scyllaridae) from Taiwan.
Five scyllarine lobsters are recorded from Taiwan for the first time. They are Bathyarctus rubens (Alcock & Anderson, 1894), Biarctus sordidus (Stimpson, 1860), Chelarctus aureus (Holthuis, 1963), Crenarctus bicuspidatus (De Man, 1905) and Petrarctus veliger Holthuis, 2002. The distributions of B. rubens, C. aureus and P. veliger are extended northwards to Taiwan. Distinguishing characters of t...
متن کاملAnalytical model for estimation of digging forces and specific energy of cable shovel
An analytical algorithm for the estimation of the resistance forces exerted on the dipper of a cable shovel and the specific energy consumed in the cutting-loading process is presented. Forces due to payload and to cutting of geomaterials under given initial conditions, cutting trajectory of the bucket, bucket’s design, and geomaterial properties are analytically computed. The excavation proces...
