Biology of Sharks and Their Relatives, Second Edition
(B) Profiles of plasma E and P in the aplacental viviparous female spiny dogfish (
Squalus acanthias). Plasma E concentrations are highest in S. acanthias during
periods of follicular development, whereas circulating P concentrations begin to ...

Management Techniques for Elasmobranch Fisheries
Elasmobranch reproductive strategies include oviparity, aplacental viviparity and
placental viviparity (Wourms, 1977). Oviparous species enclose eggs in an egg
case and deposit them into the environment, where embryos develop external to
...

The Sharks of North America
Traditionally these modes have been divided into three broad functional
categories: oviparity or egg laying, aplacental viviparity, and placental viviparity.1
These are simply functional groups and not phylogenetic categories, as some
families ...

B. Aplacental Viviparity Some aplacental species rely mainly on yolk for
development, the mother providing only protection and water (e.g., Squalus
acanthias, Scymnus, Centrophorus), but in most cases the uterine mucosa
becomes modified, ...
William Stewart Hoar, David J. Randall, Edward M. Donaldson, 1983
Viviparous sharks may be placental or aplacental depending on whether or not
there is a placental connection between the developing embryo and the mother.
Some aplacental species, like the spiny dogfish and whale shark, have no ...

Sharks of the Open Ocean: Biology, Fisheries and Conservation
Aplacental viviparity with oophagy The lamniform sharks (family Alopiidae, genus
Alopias; and family Lamnidae, genera Lamna, Isurus, and Carcharodon) all
exhibit aplacental viviparity with embryonic oophagy. Only the right ovary is ...

Sharks of the World: An Annotated and Illustrated Catalogue ...
Reproduction oviparous in some species, which lay eggs in oval cases; other
species are ovoviviparous (aplacental viviparous), with foetal nutriment from the
yolk sack or from uterine cannibalism (oophagy or egg-eating in Nebrius), but ...
Leonard J. V. Compagno, 2001
Viviparity may be aplacental, in which a definitive maternal-fetal vascular
connection is lacking, or placental, in which a vascular organ composed of both
maternal and fetal tissues mediates exchange of nutrients, gases and waste
products.

Encyclopedia of reproduction
Viviparous development is either aplacental (no morphologically definitive
vascular exchange organ formed) or placental (a maternal-fetal exchange organ
is formed). I. INTRODUCTION All elasmobranch embryos undergo an initial stage
of ...
