2020年5月1日 · Scavenging amphipods are a numerically dominant and taxonomically diverse group that are key necrophages in deep-sea environments. They contribute to the detrital food web by scavenging large food-falls and provide a food …

2023年9月22日 · Based on an integrative taxonomic approach (morphology, COI, 16S and 18S) we demonstrate the occurrence of a predatory amphipod species, Rhachotropis abyssalis, in three oceans: the Antarctic Ross...

2023年5月1日 · We compared megafauna from Nodule and Rocks areas in an abyssal nodule field. Rock bearing areas exhibit a higher diversity than those with only nodules. Hard substratum patch size positively influences the size of some taxa. Rocks and nodules are keystone structures enhancing abyssal habitat heterogeneity.

In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and ...

2024年2月19日 · Yes, the deep sea is home to a variety of large and unusual creatures, including giant squids, colossal squids, and giant isopods. These creatures have adapted to life in the abyssal depths, where they prey on smaller organisms and scavenge for food in the darkness.

We propose that they are excluded from the abyss by high-energy demand, including an oil-rich liver for buoyancy, which cannot be sustained in extreme oligotrophic conditions. Sharks are apparently confined to ca 30% of the total ocean and distribution of many species is fragmented around sea mounts, ocean ridges and ocean margins.

Deep within the world’s seas and oceans is an area called the abyssal zone. It lies more than 6,000 feet (1,800 meters) below the surface of the water. It is totally dark there, and the water is almost motionless. Yet even in these conditions various forms of life survive.

2021年7月1日 · In this study, we investigated how biotic compartments of different size classes (viruses, prokaryotes, and meio-, macro-, and megafauna) respond to environmental factors in three abyssal benthic ecosystems in the western Pacific characterized by different levels of surface productivity.

2018年3月9日 · The animals of the abyssal plain belong to the same groups as the animals of the continental shelf; you can find octopi, squid, fish, worms and mollusks there. But the animals of the abyssal plain tend to have special adaptations to …

2023年3月16日 · Deep sea gigantism (or abyssal gigantism) is the tendency for deep-sea animals, mostly invertebrates, to grow to much larger sizes than their shallow-water relatives. But...
