Dollfus' stargazer
Dollfus' stargazer (''Uranoscopus dollfusi'') is a fish of the family Uranoscopidae, widespread in the Western Indian Ocean: Gulf of Suez, Gulf of Oman, and Persian Gulf. It is a marine demersal fish, and occurs at depths down to about .〔(【引用サイトリンク】title=''Uranoscopus dollfusi'' Brüss, 1987 )〕 It was named in honour of Dr R. P. Dollfus who led an expedition to Egypt in 1928–1929 and who brought back some specimens of this fish which he mistakenly identified as ''Uranoscopus affinis''. These were new to science and became the type specimens of the new species ''U. dollfusi'', with the Gulf of Suez being the type locality.〔
