Luminescence of Argyropelecus photophores electrically stimulated

open access: yesComparative Biochemistry and Physiology Part A: Physiology, 1980
Abstract o 1. Isolated photophores of the living bathypelagic fish Argyropelecus hemigymnus respond to a strong (25–80 V) and long (4–15 msec) electrical stimulus by a brief flash emission (F response). 2. Weaker and shorter stimuli are subthreshold, but when repeated at a frequency equal to or higher than one per second, the photophores respond

A monograph of the Cephalopoda of the North Atlantic: The Family Cycloteuthidae [PDF]

open access: yes, 1969
A new family of oegopsid cephalopods, Cycloteuthidae, is erected as a result of the elevation of Naef's subfamily Cycloteuthinae. Cycloteuthis sirventi Joubin, 1919, is redescribed based on new material from the Atlantic Ocean. A new genus, Discoteuthis,

A Possible Function of Planktonic Photophores [PDF]

open access: yesNature, 1960
A NUMBER of unrelated groups of planktonic animals have developed the curious arrangement of upwardly directed eyes combined with downwardly directed photophores; this has been described and discussed by Hardy1, who has suggested a number of possible explanations.

Control of luminescence from lantern shark (Etmopterus spinax) photophores [PDF]

open access: yesCommunicative & Integrative Biology, 2011
The velvet belly lantern shark (Etmopterus spinax) is a common deep-sea shark that has been used, in the recent years, as a model for experimental studies on physiological control of shark luminescence. These studies demonstrated that, unlike any other luminous organism, the luminescence of this shark was under a dual control of hormones and ...

Recent advances in the synthesis and application of fluorescent α-amino acids [PDF]

open access: yes, 2016
Fluorescence spectroscopy has become a powerful technique for probing a range of complex biological processes including enzyme mechanisms and protein-protein interactions. While the application of this technique uses a number of strategies, many of these

Radiative forces on macroscopic porous bodies in protoplanetary disks: laboratory experiments

open access: yes, 2013
In optically thin parts of protoplanetary disks photophoresis is a significant force not just for dust grains, but also for macroscopic bodies. The absolute strength on the supposedly highly porous objects is not known in detail as yet.

A multi-gene phylogeny of Cephalopoda supports convergent morphological evolution in association with multiple habitat shifts in the marine environment

open access: yesBMC Evolutionary Biology, 2012
Background The marine environment is comprised of numerous divergent organisms living under similar selective pressures, often resulting in the evolution of convergent structures such as the fusiform body shape of pelagic squids, fishes, and some marine ...

ULTRASTRUCTURE OF A CEPHALOPOD PHOTOPHORE. I. STRUCTURE OF THE PHOTOGENIC TISSUE.

open access: yesThe Biological Bulletin, 1974
One type of photophore of the deep sea squid Pterygioteuthis microlampas was examined with the electron microscope and its fine structure described. The photogenic tissue is composed of four cell types each with distinctive morphology which suggests ...
