The giant deep-sea lobster genus Acanthacaris Bate, 1888 is reported for the first time from Taiwan. The single specimen with a total length of 36 cm was collected near a cold seep off southwestern Taiwan at about 1300 m deep and identified as A. tenuimana Bate, 1888.

Habitats in the sea, in freshwater, and on land differ dramatically in species composition and diversity. Of the roughly 1.5 million known species of macroscopic organisms on earth, the modern ocean — despite its much larger area and volume — supports only about 15% of species, whereas terrestrial environments account for about 80% of species, and freshwater for the remaining 5% (Figure 1). Eve...
Two deep-water species of caridean shrimps collected during recent dives by the Chinese manned submersible "Jiaolong" represents new records for the South China Sea: Alvinocaris longirostris Kikuchi & Ohta, 1995 (Alvinocarididae) and Acanthephyra faxoni Calman, 1939 (Acanthephyridae). Specimens of these two species were collected from Jiaolong Cold Seep I, off Guangdong Province, China (depth 1...
The deep sea shrimp genus Nematocarcinus Milne Edwards, 1881 includes 47 species, ten of them have been recorded from the Atlantic Ocean. Herein, material sampled during three scientific projects (REVIZEE Central Fishery project; Campos Basin Deep Sea Environmental Project; Evaluation of Environmental Heterogeneity in the Campos Basin) made in the Southwestern Atlantic, off Brazil, is examined....
The number of decapod species associated with the coral Pocillopora damicornis is compared between two regions on the Pacific coast of Panama which are of the same geologic age but differ in environmental characteristics. The relationship between number of species and coral head size does not differ between the two regions but species composition among coral heads is more variable in the fluctu...

A survey of studies examining crab and lobster predation on hard-shelled molluscs indicated that most predators prefer small-sized prey when offered a range of sizes. I suggest that this pattern of preference for small-sized prey can be explained by considering the mechanical cost of predation. If predation costs are assumed to be non-renewable, then the probability of exhausting them can be in...
Relationships of diversity, distribution and abundance of benthic decapods in intertidal and shallow subtidal waters to 10 m depth are explored based on data obtained using a standardized protocol of globally-distributed samples. Results indicate that decapod species richness overall is low within the nearshore, typically ranging from one to six taxa per site (mean = 4.5). Regionally the Gulf o...
