Scotoplanes globosa, commonly known as the sea pig, is a species of sea cucumber that lives in the deep sea. [1] It was first described by Hjalmar Théel , a Swedish scientist. Scotoplanes globosa , along with numerous other sea cucumbers were discovered by Théel during an expedition on HMS Challenger between the years of 1873-1876.
Scotoplanes, like many sea cucumbers, often occur in huge densities, sometimes numbering in the hundreds when observed. Early collections have recorded groups of up to 300-600 individuals. Sea pigs are also known to host different parasitic invertebrates, including gastropods (snails) and small tanaid crustaceans. [9]
In size-selective predation, predators select prey of a certain size. [81] Large prey may prove troublesome for a predator, while small prey might prove hard to find and in any case provide less of a reward. This has led to a correlation between the size of predators and their prey. Size may also act as a refuge for large prey. For example ...
The glow may also attract prey. Once the prey comes close, the Pacific viperfish can attack with its needle-like teeth. A Mid-Level Predator. In the deep ocean, many creatures are both predators ...
Prey may also reliably signal to a predator that they are difficult to catch or subdue, and that causes the predator to desist from attacking or switch their attack to another prey individual. For example, guppies might exhibit a visual signal of approaching and inspecting possible predator which communicates to the predator that the guppies ...
Just as predators on land keep prey species from outcompeting others in the environment, (such as how wolves help keep rabbit populations in check), the Venus flytrap sea anemone helps preserve ...
The linkages between predator to prey are coloured according to predator group origin, and loops indicate within-group feeding. The thickness of the lines or edges connecting food web components is scaled to the log of the number of unique ROV feeding observations across the years 1991–2016 between the two groups of animals.
I’m glad the predator gets to eat but so sad for the prey who dies,” another commenter said. “I thought it was going to be a cute dolphin video ,” a third person wrote. “And then I saw ...
