The tiny crab bridges an evolutionary gap that stumped scientists for years. Fossil stuck in 100 million-year-old amber is oldest "true crab" ever discovered Skip to main content
Loewen et al. (2024) describe a diverse amber deposit from the Maastrichtian strata from the Big Muddy Badlands , preserving fossils of representatives of seven arthropod orders and at least 11 insect families, and interpret the studied assemblage as providing evidence of a faunal turnover among insects prior to the Cretaceous–Paleogene ...
The discovery comes from a fossil of an ancient firefly species that was initially discovered in 2016, trapped in 99 million-year-old Burmese amber from northern Myanmar. The beetle is only the ...
Capture (blue) and aquaculture (green) production of Indo-Pacific swamp crab (Scylla serrata) in thousand tonnes from 1950 to 2022, as reported by the FAO [1]Scylla serrata (often called mud crab or mangrove crab, although both terms are highly ambiguous, and black crab) is an ecologically important species of crab found in the estuaries and mangroves of Africa, Australia, and Asia.
Mangrove crabs are predated on by wading birds, fish, sharks, [8] monkeys, hawks, and raccoons. [7] The larvae of mangrove crabs is a major source of food for juvenile fish in waterways near the crabs. [24] Adult mangrove crabs are food for the crab plover among other protected species. [17] To protect themselves the crabs can climb trees. [25]
Billions of crabs ultimately starved to death, devastating Alaska’s fishing industry in the years that followed. Molts and shells from snow crab sit on a table in June at the Alaska Fisheries ...
Billions of snow crabs have disappeared from the ocean around Alaska in recent years, and scientists now say they know why: Warmer ocean temperatures likely caused them to starve to death.
