The synurids are a small group of heterokont algae, found mostly in freshwater environments, characterized by cells covered in silica scales.
Christian Gottfried Ehrenberg was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. Ehrenberg was an evangelist and was considered to be of the most famous and productive scientists of his time.
Wilhelm Friedrich Hemprich was a German naturalist and explorer.
Actiniidae is the largest family of sea anemones, to which most common, temperate, shore species belong. Most members of this family do not participate in symbioses with fishes. Three exceptions are the bubble-tip anemone, snakelocks anemone and Urticina piscivora.
The sebae anemone, also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone belonging to the family Stichodactylidae and native to the Indo-Pacific area.
The pulsating xenid is a species of soft coral in the family Xeniidae. The species was first described in 1834 by Christian Gottfried Ehrenberg as Xenia fuscescens.
The sooty gull is a species of gull in the family Laridae, also known as the Aden gull or Hemprich's gull. It is found in Bahrain, Djibouti, Egypt, Eritrea, India, Iran, Israel, Jordan, Kenya, Lebanon, Maldives, Mozambique, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sri Lanka, Sudan, Tanzania, United Arab Emirates, and Yemen. As is the case with many gulls, it has traditionally been placed in the genus Larus. The sooty gull is named in honour of the German naturalist Wilhelm Hemprich who died in 1825 while on a scientific expedition to Egypt and the Middle East with his friend Christian Gottfried Ehrenberg.
Stichodactyla is a genus of sea anemones, of the family Stichodactylidae. They are host anemones, which maintain a relationship mutualistic with other animals, in their case with crabs of the genus Mithraculus, shrimp of the genus Periclimenes , and with various species of clownfish, of the genus Amphiprion, establishing a relationship of coexistence. In this way, crabs and fish protect themselves from their predators between the stinging tentacles of the anemone, and the anemone benefits from the cleaning of its oral disc and tentacles as a result of the continuous movements of the animals.
Urticina is a genus of relatively large and often colorful sea anemones in the family Actiniidae from the North Pacific, North Atlantic and Arctic Oceans.
Lobophyllia hemprichii, commonly called lobed brain coral, lobed cactus coral or largebrain root coral, is a species of large polyp stony coral in the family Lobophylliidae. It is found in the Indo-Pacific Ocean. In its specific name Christian Gottfried Ehrenberg honoured his late partner the Prussian naturalist Wilhelm Hemprich; they were among the first to study the marine life of the Red Sea.
Acropora millepora is a species of branching stony coral native to the western Indo-Pacific where it is found in shallow water from the east coast of Africa to the coasts of Japan and Australia. It was first described in 1834 by Christian Gottfried Ehrenberg as Heteropora millepora.
Anemonia is a genus of sea anemones belonging to the family Actiniidae.
Acropora hemprichii is a species of acroporid coral that was first described by Christian Gottfried Ehrenberg in 1834. It lives in reefs at depths of 3 to 15 m for between 13 and 24 years. The species is listed as vulnerable on the IUCN Red List, and has a decreasing population. It is common with a wide range, and is listed on Appendix II of CITES.
Acropora microclados is a species of acroporid coral that was first described by Christian Gottfried Ehrenberg in 1834. Found in marine, tropical shallow reefs on the upper slopes, it is found at depths of 5 to 20 m. It is listed as a vulnerable species on the IUCN Red List, and its population is decreasing. It is uncommon but found over a large area, including in five regions of Indonesia, and is classified under CITES Appendix II.
Gyrosmilia is a monotypic genus of large polyp stony coral. It is represented by a single species, Gyrosmilia interrupta. It was first described by Christian Gottfried Ehrenberg in 1834 as Manicina interrupta.
Anthopleura stellula is a species of sea anemone in the family Actiniidae. It was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg as Actinia (Isacmaea) stellula. It is found in the Indian Ocean and the Red Sea, and is unusual among sea anemones in that it can divide itself in two transversely.
Thalassianthidae is a family of sea anemones that contains the genera Actineria, Cryptodendrum,Heterodactyla, and Thalassianthus. These sea anemones do not host any varieties of clownfishes, but have been associated with some species of commensal anemone shrimp.
Thalassianthus aster is a species of sea anemone in the family Thalassianthidae. It dwells in a number of habitats, even existing symbiotically on top of other motile invertebrates such as hermit crabs in a relationship similar to the pom pom crab. Its nematocysts contain a Type-II Na+-channel toxin known as δ-TLTX-Ta1a according to the currently developing systematic nomenclature for peptide and protein toxins from sea anemones.
Heterodactyla is a genus of sea anemones of the family Thalassianthidae. The genus was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg.
Favites halicora is a species of coral belonging to the family Merulinidae. The species was first described in 1834 by Christian Gottfried Ehrenberg as Astraea halicora.
