Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.
Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.
Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.
Ik that u would do it from a ship, and i also know that they could send a diver down there or they could send the crane arm down there with a scoop from the ship and pull up some sand and use that as a sample
Well-sorted sediments have grains of similar size, and are the result of much sediment transport and earth processes which segregated the sediment by depositing different size fractions in different places.
The correct answer is "wildlife sanctuary"
These sanctuaries are places that emulate conditions met in natural habitats that are long gone and thus the animals that live in them have a place to live freely and survive.
