With positive buoyancy (e.g. floating fruit), ocean surface currents freely move propagules, and dispersal distances are only limited by the viability time of the fruit, [55] [56] leading to exceptionally long single dispersal events (more than 100 km), [57] which is rare for passive abiotic movement of terrestrial fruit and seeds.
Monocots are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf or cotyledon. [12] Terrestrial plants evolved perhaps as early as 450 million years ago from a group of green algae. [13] Seagrasses then evolved from terrestrial plants which migrated back into the ocean.
However, it is the only home to the snowy cotinga, the sulphur-rumped tanager, the stripe-cheeked woodpecker, and the streak-crowned antvireo. Additionally, the Caribbean slope is a major migratory route for birds. 30% of the birds in that region migrate through the Neotropical realm annually, especially on the foothills.
Inside the pods are ten to fifteen seeds, each of which have a diameter of 6 cm (2.4 in) and a thickness of 2 cm (0.79 in). [6] The seeds contain a hollow cavity, which gives them buoyancy. After being washed by rain into rivers and then the ocean, the seeds of E. gigas drift long distances on ocean currents. Seed buoyancy and vitality lasts at ...

The Cosmic Ocean Reveals Brahma, Vishnu, Shiva (opaque watercolor and gold on paper, San Diego Museum, 1835). A cosmic ocean, cosmic sea, primordial waters, or celestial river is a mythological motif that represents the world or cosmos enveloped by a vast primordial ocean. Found in many cultures and civilizations, the cosmic ocean exists before ...
The felsic nature of Laurentia allowed it to float over the denser ocean basins that surrounded it, so it was not submerged under the then-forming oceans. During the Archean Eon the surface of New England was a coastal desert covered by silica -rich sediments with outcroppings of granite bedrock .
Technically, a seed oil is a cooking oil made by pressing seeds to extract the fat. But the current pariahs are canola, corn, cottonseed, grapeseed, soy, rice bran, sunflower, and safflower oils.
