Night smelt spawn along sandy open coasts and coarse sandy beaches often in proximity to river or creek mouths in north-central to northern California. [3] [1] However, little is known about the movement of night smelt in California. [1] They spawn nocturnally in courser sand grain sizes and spawning generally occurs from January to September. [4]
Emerita is a small genus of decapod crustaceans, [3] known as mole crabs, sand fiddlers, sand fleas or sand crabs. These small animals burrow in the sand in the swash zone and use their antennae for filter feeding. [4] [5]
The carapace width of mature Dungeness crabs may reach 25 cm (9.8 in) in some areas off the coast of Washington, but are typically under 20 cm (7.9 in). [22] They are a popular delicacy, and are the most commercially important crab in the Pacific Northwest, as well as the western states generally. [23]
During the night, a plant employing CAM has its stomata open, allowing CO 2 to enter and be fixed as organic acids by a PEP reaction similar to the C 4 pathway. The resulting organic acids are stored in vacuoles for later use, as the Calvin cycle cannot operate without ATP and NADPH, products of light-dependent reactions that do not take place ...
Pelagic red crab (Grimothea planipes)Grimothea planipes usually feeds on protists and zooplankton, but will feed by filtering blooms of diatoms. [7]As the most abundant species of micronekton in the California Current, Grimothea planipes fills an important ecological niche converting primary production into energy that larger organisms can use. [8]
The crabs can measure up to 3-feet across, have claws with astounding crushing power, and are able to sniff out their prey. They have also been proven capable of gaining an advantage over animals ...
Sub-adults are more active at night and have a more diverse diet with their preferred prey being more active at night. As adults, kelp bass feed on small fish, crustaceans, mollusks, and other small primary consumers. In winter, their feeding options are far more limited than in summer, and many Kelp Bass go hungry.
Its range is from Monterey Bay, California, to the Gulf of California, Mexico. [5] It can live for over 50 years and can reach a size of up to 91 cm (3 ft) and a weight of 16 kg (35 lb). [ 5 ] It is carnivorous , living in rocky reef and kelp bed habitats, feeding primarily on sea urchins , molluscs , and crustaceans .
