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]
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.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The sea otters eat while floating on their backs, using their forepaws to tear food apart and bring to their mouths. [64] [65] Marine otters mainly feed on crustaceans and fish. [66] Pinnipeds mostly feed on fish and cephalopods, followed by crustaceans and bivalves, and then zooplankton and warm-blooded prey (like sea birds).
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 ...
Rats are by far the most common introduced mammals on seabird islands. [2] [3] Currently, approximately 80% of islands worldwide have populations of introduced rats. [2]The most common introduced species is the Norway rat (Rattus norvegicus), but black rats (R. rattus, also known as “ship rat”) and Polynesian rats (R. exulans) have found their way to offshore islands and have subsequently ...
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 ...
The sea cucumber, like other bioluminescent animals, is able to emit light. It uses this effect as an alarm to expose its self and potential predators in times of an attack.
