Deep-Sea Creature Adaptions Deep-Sea creatures in the Bathypelagic Zone and lower must adapt to survive. Adapting to this harsh environment didn’t take only a few years, this process has occured over millions of years and will continue to occur. Some characteristics that the organisms adapted are things like: the ambush strategy, extended spines, smaller sizes, deep-sea giantism, bioluminescence, transparant skins, large mouths, large teeth, large stomachs, large eyes, slow metabolic rates, lateral lines, hermaphroditism, and chemosynthesis. Scientists are still searching in the deep-sea because for organisms still not discovered. All of these adaptions contribute to the survival of deep-sea creatures in the low pressure, temperature, and low food source environment.
Bathypelagic Zone Adaptions 1,000-4,000 (3,000-13,000 ft) meters deep in the ocean where there is a total abscence of sunlight. The large, dark ocean lessens the chance of animals catching prey. This zone has the greatest temperature changes compared to the other zones, it contains thermocline, which causes water temperatures to change dramatically with depth. In this wide ocean, all organisms do not have the energy to endlessly search for food, forcing many organisms to adapt to a strategy called “The Ambush Strategy”, which is when they sit and wait for prey to get closer and they attack them when the food when they’re close enough, they have also adapted to having a long dorsal spine that floats above its head with a photophore which acts as a “fishing pole” to bait other animals. An example of this sort of fish is called the Deep-Sea Angler. Animals in this zone also adapted to be smaller in size because they are entirely made of water with no air space due to high pressures. If they had air space inside of them, the open space in their body would crush them completely. The pressure of the Bathypelagic Zone is 800 times greater than the surfaces pressure. This is the cause of their less developed internal organs, small eyes, thinner skin, smaller sizes compared the animals in the Mesopelagic and Epipelagic Zone, which are located above the Bathypelagic Zone. If humans were to go down to these depths we’d be crushed, this is caused by all
