Camels imported from Africa enter Egypt at Southeast borders. Movement of life animals help spreading of transboundary diseases from endemic areas to free areas. Lappet-faced vulture in Egypt territory represents highly valuable gift of nature, it is recorded in Red sea zone of Egypt. Their numbers indicate vulture breeding rate was promising for such endangered species. The Egyptian authority played a great role in protecting this land from destructive behavior against wild life. The raven accompany lappet-faced vulture, while eating together, which indicates healthy atmosphere at their habitat. This work performed while studying the epidemiology of this region and the impact of movements of live animals coming from Africa on trans-boundary diseases. Lappet-faced vultures and Raven play major role in preventing transmission of infectious agents from camel carcasses. However, Vulture has strong digestive system that kill a wide range of harmful microorganisms. Moreover, these scavenge birds are considered dead end hosts for these diseases. The study provides vivid proof of the innate intelligence that distinguishes the raven, as well as evidence that the black bird possesses a common language among themselves and between them and the Lappet-faced vulture. Lappet-faced vulture is usually nesting at acacia trees & mountains. However some acacia trees showed defected growth as a result of the strong wind, such observation is of great importance to understand geography of such habitat. Lappet-faced vulture is endangered species and need more attention and care.

The present study introduce an overview on the cladal structure of Symbiodinium population associated with some species of scleractinean corals and fire coral in the Egyptian Red Sea coast and discuss the possible consequences of recent climate changes on coral reefs. Cladal structure of Symbiodinium populations associated with eight keystone species of scleractinean corals and one species of fire coral that collected along Egyptian Red Sea coast, during 2012-2013, had been resolved based on 18S nrDNA and ITS2 genetic markers. Only Symbiodinium subclades C1 and A1 were identified from all examined species. Symbiodinium C1 was the dominant subclade that associated with 61% of coral samples. Results revealed that the studied pocilloporid corals were associated with Symbiodinium C1 and/or A1 while acroporids were only associated with Symbiodinium C1. The present data also indicated that Symbiodinium C1 occurred at high densities than A1 or A1+C1 combination. Because of the relative thermal susceptibility of clades C and A, the current study addresses that the recent climate changes may derive dramatic changes on community structure of coral reefs at the Red Sea.

The Anthomedusae species, Corymorpha bigelowi Maas, 1905 (Cnidaria: Hydrozoa, Corymorphidae), was recorded in the northern Red Sea fauna, representing it "first invasion" in Egypt. A fact proven by past studies that this species is endemic in the Indo-Pacific region, which is mainly located in southern coast of Japan and Indian Ocean. The specimens were collected from an area located off Hurghada city, and between latitudes 27° 14.427ˊ and 27° 10.816ˊ N, and longitudes 33° 51.085ˊ and 33° 51.603ˊ E using plankton net (350 µm mesh). In total, six mature medausae of C. bigelowi were caught in December 2014 and February 2015 (4 and 2 medusae, respectively). Following this, the captured species medusa of C. bigelowi was photographed and morphological characteristics described in details. As well as, further discussions of biogeographical distribution and morphological speciation of the present species were provided. This work makes a noteworthy contribution to clarify the migration route of C. bigelowi from southern Red Sea to the Mediterranean Sea. nih.gov/pmc/articles/PMC3155160/
