These collective rafts of kelp or seagrass allow the otters to stay close and connected and avoid drifting apart. This is especially useful when it comes to enjoying a nice nap while floating ...
The kelp floats as a raft and can travel vast distances at sea, driven by ocean currents. Kelp-associated invertebrates can be transported inside of drifting holdfasts, potentially leading to long-distance dispersal and a significant impact upon the population genetic structure of those species. [26] [27] [28] [29]
Kelp have had to adapt dispersal methods that can make successful use of ocean currents. Buoyancy of certain kelp structures allows for species to disperse with the flow of water. [21] Certain kelp form kelp rafts, which can travel great distances away from the source population and colonize other areas.
[8] [9] Specimens of D. antarctica have been found to float for up to 210 days, during which time high wind speeds transport kelp rafts up to 10,000 km. [8] [9] Environmental factors such as temperature, solar radiation and surface winds (all of which vary with latitude) affect buoyancy of southern bull kelp rafts and their rate of travel. [8]
Laminaria is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size.
The team of divers was training in the giant kelp forests of eastern Santa Cruz Island in California’s Channel Islands National Park. Curious sea creature follows diver in kelp forest — and ...
It is commonly known by the names sea raft, by-the-wind sailor, purple sail, little sail, or simply Velella. [ 3 ] This small cnidarian is part of a specialised ocean surface community that includes the better-known cnidarian siphonophore , the Portuguese man o' war .
Blades from southern bull kelp (rimurapa in Māori) [1] [2] [3] species such as Durvillaea antarctica and D. poha (named after the pōhā) [4] [5] were used to construct the bags. [1] The kelp blades have a 'honeycomb' structure, [ 6 ] [ 7 ] which allows them to be split open, hollowed out (pōhā hau) and inflated into containers.
