Sea hares, Abalone, Sea Urchins, Sea Snails, Kelp Crabs, some fish (half moon and opaleye), and people. Recent reports of sea otter sightings have also occurred in Mexico. Kelp thrives in cold, nutrient-rich waters. Dobkowski K(1)(2). The grey whale will eat the abundant invertebrates and crustaceans in kelp forests. Additionally, sea otters indirectly help to reduce levels of atmospheric carbon dioxide, a prevalent greenhouse gas, as kelp forests play an important role in capturing carbon in coastal ecosystems.

An animal that can change its diet seasonally is always at an advantage. As predators, sea otters are critical to maintaining the balance of the near-shore kelp ecosystems. These fairly large and not particularly evasive crabs are obviously excellent prey items for a shellfish predator that hangs out in kelp beds. Kelp forests are a natural buffet for birds such as crows, warblers, starlings, and black phoebes which feed on flies, maggots, and small crustaceans that are abundant in kelp forests. In 2007, kelp forests were also discovered in tropical waters near Ecuador.. Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms and are a source for understanding many ecological processes. Coastal kelp forests are one of the most productive ecosystems on the planet, with giant kelp (Macrocystis pyrifera) growing as much as a metre a day during peak growing seasons. Sea otters eat approximately 25% of their weight in food each day to support their high metabolism. Such females are absent for several summer months, and it is thought they move to deeper water then. For example, many types of rockfish such as black rockfish, blue rockfish, olive rockfish, and kelp rockfish are found in kelp forests and are important to fishermen. Kelp forests are characterized by extremely high rates of primary productivity, comprise the base of a complex food web, form a three-dimensional structure that provides physical shelter for many inhabitants, have large algal standing stocks within forests, and export substantial biomass as drift algae that support other coastal ecosystems (Graham et al., 2003; On view at the Aquarium in Kelp Forest. Kelp forests house sea urchin predators that regulate sea urchin abundance: Medium correlative: Sea urchins rarely observed inside kelp forests: Norderhaug and Christie , Skadsheim et al. Outside the holdfasts, sponges, tunicates, anemones, cup corals and bryozoans are probably the most commonly occurring sessile animals within kelp forests (Foster and Schiel 1985; Table 1). A commercial urchin diver removes purple urchins as part of a kelp forest restoration project near Fort Bragg. Today, there are estimated to be just over 106,000 worldwide, with just under 3,000 in California. Also like a terrestrial forest, kelp forests experience seasonal changes. Large decorator crabs don’t decorate as much as smaller crabs. In kelp forests, the most commonly found invertebrates are bristle worms, scud, prawn, snails, and brittle stars. King crabs live among the kelp and help to keep the sea urchin populations in check. McLean (1962) observed 204 species of invertebrates living in a bull kelp forest along an exposed coast south of Carmel during 30 SCUBA dives. A wide range of marine mammals inhabit kelp forests for protection and food. Kelp forest ecosystems include structure-producing kelps and their myriad associated biota such as marine mammals, fishes, crabs, sea urchins, molluscs, other algae Other invertebrates found in kelp forests are sea stars, anemones, crabs, and jellyfish. Kelp forests are habitat for Cancer crabs Strong causal This creation is based off the kelp forests and species along the Oregon coast and features: Kelp, a Sunstar, a Giant Pacific Octopus, Sharks, Rock Fish, Sea Stars, Crabs, Tube Sponges, Barrel Sponges, Seaweed, Feather Duster Tube Worms, a Green Eel, Clams, Jellyfish, and three types of Sea Anenomies. Northern kelp crabs are known for their association with kelp and their similar coloration. The Northern kelp crab (Pugettia producta) and the graceful kelp crab (Pugettia gracilis) are both common in kelp beds in the Pacific Northwest, but to what degree they feed on the dominant canopy-forming kelp (N. luetkeana), as compared to other macroalgal, invertebrate, or detrital food choices, remains less well-studied. The eggs take about a month to hatch into tiny zoea larvae. The holdfast has many crevices and is home to many other animals such as spiny brittlestars and amphipods. Natural history. this species is usually dark brown, with a roughly squareish carapace except for the pointed front. There is an order of magnitude less litter on the floor of a kelp forest Discover (and save!) Other invertebrates found in kelp forests are sea stars, anemones, crabs, and jellyfish. Kelp anchors to the rocky bottom with a structure called the holdfast. During the summer they nip off bits of brown algae such as kelp, rockweed, and sargassum, as well as several types of red algae.
