The Bolosoma are benthic organisms that live exclusively in the deep sea, preferring hard, rocky substrates such as old lava flows. This genus is found as deep as over 3,700 meters in some parts of the Pacific Ocean. [5] In these environments, Bolosoma species can be the dominant benthic species, being incredibly common in areas such as ...
Natrocarbonatite is a rare carbonatite lava which erupts from the Ol Doinyo Lengai volcano in Tanzania within the East African Rift of eastern Africa. Natrocarbonatite lavas were first documented in 1962, by J. B. Dawson. [1] [2]
The giant volcano sponge (Anoxycalyx joubini) is a species of Antarctic sponge. [1] It is one of the largest sponges in the world which can grow up to a diameter of 1.5 metres (5 feet) and 1.95 metres (6.5 feet) in height. [2] The species may have an extremely long lifespan, with estimates of up to 15,000 years. [3]
MANILA, Jan 16 (Reuters) - A central Philippine province declared a state of calamity on Tuesday as a volcano spewed lava that reached the limits of a six-km radius no-go zone and spread ash on ...
The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. [1] Sponge spicules are made of calcium carbonate or silica. Large spicules visible to the naked eye are referred to as megascleres or macroscleres, while smaller, microscopic ones are termed microscleres.
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
This sponge has a somewhat flattened spherical body, with a large lateral opening on one side of the body measuring about 50 millimetres (2.0 in). The body, which is 136 millimetres (5.4 in) in diameter, is held up by a lengthy peduncle longer than 154 millimetres (6.1 in), at least four times the size of the body.
A SAP's ability to absorb water depends on the ionic concentration of the aqueous solution. In deionized and distilled water, a SAP may absorb 300 times its weight [4] (from 30 to 60 times its own volume) and can become up to 99.9% liquid, and when put into a 0.9% saline solution the absorbency drops to approximately 50 times its weight.
