Objectives: The aim of the study is to highlight variations in facial anthropometric measurements among the major ethnic groups in Nigeria using 3D photogrammetry. Materials and Methods: This study was conducted in Lagos, Nigeria. Acquisition of 3D facial photographs was done using a Vectra H1 portable 3D photogrammetry imaging system. Descriptive analysis of collected data was done and a test of associations performed using independent samples t-test. The level of significance was set at <.05. Results: The total number of participants in this study was 503. The study population was made up of 302 (60%) males and 201 (40%) females. Mean upper facial height among Yoruba, Igbo, Hausa, and other ethnic groups were 68.93 ± 5.85, 70.18 ± 5.99, 63.79 ± 4.80, and 69.29 ± 5.95 mm respectively, while mean interpupillary distances were 66.99 ± 3.70, 67.34 ± 3.56, 66.73 ± 3.80, and 67.09 ± 3.72 mm respectively. A Tukey posthoc test revealed significant pairwise differences for upper facial height between the Yoruba and Hausa population with a mean difference of 5.15 mm ( P < .001, 95% CI 2.94-7.35) ( P < .001, 95% CI 2.94-7.35), and Hausa and Igbo population with a mean difference of 6.39 mm ( P < .001, 95% CI 3.75-9.03). Multivariate regression analysis confirmed the presence of significant inter-ethnic differences between Hausa ethnic group and the Yoruba ethnic group for midfacial height ( P < .001), upper lip height ( P = .004), lower lip height ( P = .003), total face height ( P = .010), and orbital fissure width ( P < .001). Conclusion: The result of this study shows that distinct difference does exist in the facial anthropological measurements between the ethnicities included in this study especially in vertical facial measurements.

Harlequin crabs, Lissocarcinus orbicularis, are commensals found on the integument and in the buccal/cloacal cavity of several species of holothuroids. The population of these crabs was investigated on holothuroids of the barrier reef of Toliara (South-West of Madagascar) from 2002 to 2008. Seventeen holothuroid species were observed and eight were crab hosts. There is generally one adult crab or a heterosexual pair per infested holothuroid but up to ten juveniles were recorded on a Thelenota ananas. Carapace length of the observed L. orbicularis was from 0.3 to 1.4 cm from the tip of the rostrum to the end of the cephalothorax, with a mean length of 0.85 cm. L. orbicularis is characterized by a weak sexual dimorphism (females are bigger than males) and the presence of pereiopods morphologically adapted to fixation on the host integument. Gravid females were observed at each month of the survey indicating that the crab reproduces all the year. Considering our results and personal observations, we also discuss the monogamy mating system of the Harlequin crab.

Mah Meri (ãʔ məri) belongs to the Aslian branch of Mon-Khmer within the Austroasiatic family. It is classified as a Southern Aslian language, along with Semelai, Semoq Beri and Temoq (Benjamin 1976). Mah Meri is spoken by the Mah Meri ethnic group in scattered settlements along the south-west coast of the Malay peninsula stretching from Port Kelang to Bukit Bangkong, Sepang in the state of Selangor, Malaysia. The island of Sumatra lies a short distance away across the Malacca Strait. The Mah Meri language, which may have as many as 2,185 speakers, has no written tradition and is highly endangered.

This study has attempted to examine perceived discrimination difference between the Manjo clan and non-manjos in Kaffa zone that is located in the south west of Ethiopia. A total of 298 individuals who belong to the manjo and non-manjo groups were randomly selected and involved in the study. The researchers utilized an independent sample t-test to compare the level of perceived discrimination between the Manjo and the non-Manjos ethnic groups. Seen segregation is the changeability of thought coming because of behavior of isolating group of people that radiates from predisposition and partiality. As revealed in the study, there is a significant mean variation among manjos and non-manjos with respect to perceiving discrimination. The thought of being discriminated showed significant mean difference between the group of manjos and non-manjos. The finding implies the need for further research and social work intervention to minimize the action and sense of being discriminated as this relates to the overall psychosocial wellbeing of persons in a given community.
