Their bodies taper to points at both the snout and the tail, reducing water resistance. Also decreasing drag -- and therefore noise -- are dermal denticles, sharp scales that cover the skin of most shark species. Rather than bone, sharks have cartilage, which is much lighter and more flexible. In addition, their livers produce squalene, a fatty oil that helps them remain afloat. Their pectoral fins allow them to quickly change direction, dive and swim upward.

Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.

hi i need a definition of adaptation, camouflage, habitat, hibernation, migration, mimicry, niche, predator, prey, reproduction,
gladu [14]
Answer:
species is a group of organisms of common ancestry able to reproduce only among. reproduction is Formation of new cells or a new individual. adaptation is A changing to fit new conditions. niche is ecology) the status of an organism within its environment and community (affecting its survival as a species). camouflage is camouflage. mimicry is Gaining protection by looking and acting like a different species. migration is Form of relocation diffusion involving permanent move to a new location. hibernation is A state of extremely low metabolism and respiration, accompanied by lower-than-normal body temperatures. predator is An animal that hunts other animals for food. prey is Animal hunted or caught for food. habitat is Place where an organism lives. organism is any living thing made up of one or more cells. invasive species is plants and animals that have migrated to places where they are not native. last non native species is not from an area, usually harmful.
