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]
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

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.

Any large body of water with "Sea" in the name, including lakes. River – a narrow strip of water that flows over land from a higher elevation to a lower one
Multiple causes including global cooling, polar glaciation, falling sea levels, and the Popigai impactor [12] Cretaceous: Cretaceous–Paleogene extinction event: 66 Ma Chicxulub impactor; the volcanism which resulted in the formation of the Deccan Traps may have contributed. [13] Cenomanian-Turonian boundary event: 94 Ma
Sea-level falls: 12, of which seven were associated with significant extinctions. [f] Asteroid impacts: one large impact is associated with a mass extinction, that is, the Cretaceous–Paleogene extinction event; there have been many smaller impacts but they are not associated with significant extinctions, [105] or cannot be dated precisely enough.
The Bathysphere on display at the National Geographic museum in 2009. The Bathysphere (from Ancient Greek βαθύς (bathús) 'deep' and σφαῖρα (sphaîra) 'sphere') was a unique spherical deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934.
