The Mytilus californianus: The Larvae’s Ecological Niche a Trade-offs of becoming an Adult Marine organisms that have a larvae stage dependent on wind waves to move and settle in an environment‚ where they develop to adults and recruit. The Mytilus californianus has a larvae stage and as the waves break into the surface of the pier pilings in Santa Monica‚ the larvae stick to the hard substrate that the vertical columns provide. The random placement of the larvae on the pier piling is what determines

A niche is a species and their position in their habitat or ecosystem‚ having a specialized strength that no other species have or does. Why it’s important in biodiversity? Species have different preys and predators because how diverse the energy web is. An example between two organisms and their position in their habitat would be the relationship between a sea anemone and a hermit crab. The sea anemone can either be a predator trying to catch prey when walking into the mouth. As hermit crabs can

Loggerhead turtles have many significant adaptations to their current and past environments. Turtles of the family Cheloniidae have various morphological adaptations for aquatic life. Early turtles lost the capacity for aquatic propulsion by body and tail undulations when they developed a shortened‚ more rigid body form during the Triassic‚ as an adaptation for armored resistance to attack by predators. However‚ terrestrial body form with a carapace and walking-type limbs precluded aquatic locomotion
