The egg capsules, eggs and embryos of the muricid gastropod Coronium coronatum are described for the first time. Capsules are sessile, bulliform, semi-circular, with a plug in the dorsal center. Sutures split the capsule ...

This experiment aimed at evaluating the influence of different heating times of settable eggs of Cobb 500® broiler breeders before submitting them to different storage periods on egg weight loss, embryo mortality, and ...

Predation of eggs and embryos is one of the reasons of early mortality in anurans, and it is known that embryos of several amphibian species can accelerate its hatching, as a mechanism to reduce predation risk. Several ...

The egg capsules, eggs and embryos of the muricid gastropod Trophon acanthodes are described for the first time. Egg capsules are sessile, bulliform, semi-circular, about 20 mm in diameter, with a plug in the centre of the ...

Naticids are common predators in sandy bottoms of shallow waters around the world. Probably due to their infaunal habitat, they are hard to find alive, particularly in the Patagonian waters of Argentina. Nevertheless, their ...

Objective To study morphologically the eggs of T. circummaculata and T. rubrovaria. Methods Ferry eggs of the two species were measured through Nikon model 6C profile projector Student test was utilized for the statistical ...
