Dipsacaster is an extinct genus of sea stars in the family Astropectinidae. It was described by Alcock in 1893, [1] and is known from France and Morocco. [2] It contains the species D. jadeti and D. africanus. [2]
The Decapoda or decapods are an order of crustaceans within the class Malacostraca, and includes crabs, lobsters, crayfish, shrimp, and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 extant species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp and Anomura including hermit crabs, porcelain crabs, squat lobsters making up the bulk of the remainder. The earliest fossils of the group date to the Devonian.
James Wood-Mason was an English zoologist. He was the director of the Indian Museum at Calcutta, after John Anderson. He collected marine animals and lepidoptera, but is best known for his work on two other groups of insects, phasmids and mantises.
Alfred William Alcock was a British physician, naturalist, and carcinologist.
King crabs are a taxon of decapod crustaceans that are chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food with the most common being the red king crab.
The Barbary lion, also called the North African lion, Atlas lion, and Egyptian lion, is an extinct population of the lion subspecies Panthera leo leo. It lived in the mountains and deserts of the Maghreb of North Africa from Morocco to Egypt. It was eradicated following the spread of firearms and bounties for shooting lions. A comprehensive review of hunting and sighting records revealed that small groups of lions may have survived in Algeria until the early 1960s, and in Morocco until the mid-1960s. Today, it is locally extinct in this region. Fossils of the Barbary lion dating to between 100,000 and 110,000 years were found in the cave of Bizmoune, near Essaouira.
The family Polychelidae contains thirty-eight extant species of blind, benthic lobster-like crustaceans. They are found throughout the world's tropical, sub-tropical and temperate oceans, including the Mediterranean Sea and the Irish Sea.
Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago. It was a pelagic fish inhabiting open waters, and one of the first apex predators of any ecosystem.
Cithaeronidae is a small family of araneomorph spiders first described by Simon in 1893 Female Cithaeron are about 5 to 7 millimetres long, males about 4 millimetres (0.16 in).
The African wildcat is a small wildcat species with sandy grey fur, pale vertical stripes on the sides and around the face. It is native to Africa, West and Central Asia, and is distributed to Rajasthan in India and Xinjiang in China. It inhabits a broad variety of landscapes ranging from deserts to savannas, shrublands and grasslands.
The quagga catshark is a species of catshark, belonging to the family Scyliorhinidae. A small, slim-bodied shark reaching 37 cm (15 in) in length, it has a distinctive color pattern of narrow, dark brown vertical bars, which resemble those of the quagga. Its head is short and flattened, with a pointed snout tip that is not upturned.
The bristly catshark is a cat shark of the family Scyliorhinidae, found from southeastern India and the Andaman Islands, between latitudes 15° N and 5° N, at depths between 200 and 300 m. Its length usually ranges from around 20–26 cm, and it is regarded as the smallest catshark of Bythaelurus.
Charybdis is a genus of swimming crabs in the family Portunidae. It is named after the monster Charybdis of Greek mythology.
Chikila fulleri, also known as the Kuttal caecilian, Fuller's caecilian, and Fuller's chikila, is a species of caecilian from South Asia. In 2012 it was reassigned to a newly erected family, Chikilidae.
The 2004 Al Hoceima earthquake occurred on 24 February at 02:27:47 local time near the coast of northern Morocco. The strike-slip earthquake measured 6.3 on the moment magnitude scale and had a maximum perceived intensity of IX (Violent) on the Mercalli intensity scale. Between 628 and 631 people were killed, 926 were injured, and up to 15,000 people were made homeless in the Al Hoceima-Imzourene-Beni Abdallah area.
Munidopsis is a genus of squat lobster. It is the second largest of all the genera of squat lobsters, after Munida, with over 200 species. Its members are mainly found on continental slopes and on abyssal plains. A few fossil species are also known, including specimens from the Campanian (Cretaceous).
The family Homolidae, known as carrier crabs or porter crabs, contains 14 genera of marine crabs. They mostly live on the continental slope and continental shelf, and are rarely encountered. Members of the Homolidae have their fifth pereiopods in a sub-dorsal position, which allows them to hold objects in place over the rear half of the carapace. The objects carried include sponges, black corals and gorgonians, and this behaviour may be a defence mechanism against predators. Some species have been observed carrying living sea urchins in a symbiotic relationship which allows them to benefit from the protection of the urchin's dangerous spikes.
Lovenia is a genus of sea urchin that is the sister taxon to Breynia and Echinocardium.
Bathycongrus macrocercus is an eel in the family Congridae. It was described by Alfred William Alcock in 1894, originally under the genus Congromuraena. It is a marine, deep water-dwelling eel which is known from the Andaman Islands, in the eastern Indian Ocean.
Climate change in the Middle East and North Africa (MENA) refers to changes in the climate of the MENA region and the subsequent response, adaption and mitigation strategies of countries in the region. In 2018, the MENA region emitted 3.2 billion tonnes of carbon dioxide and produced 8.7% of global greenhouse gas emissions (GHG) despite making up only 6% of the global population. These emissions are mostly from the energy sector, an integral component of many Middle Eastern and North African economies due to the extensive oil and natural gas reserves that are found within the region. The region of Middle East is one of the most vulnerable to climate change. The impacts include increase in drought conditions, aridity, heatwaves and sea level rise.
