Acanthotetilla Celebensis
''Acanthotetilla celebensis'' is a species of sea sponge belonging to the family Tetillidae. It is only known from a single specimen collected at a depth of 14 m off Bunaken Island, north Sulawesi, Indonesia. This firm yellow sponge] is roughly hemispherical and around 12 cm across. Like other species of the genus ''Acanthotetilla ''Acanthotetilla'' is a genus of demosponges belonging to the family Tetillidae Tetillidae is a family of marine sponges. Tetillids are more or less spherical sponges (sometimes referred to as golf ball sponges) which are found commonly in all ...'', it is characterized by the presence of distinctive spiny spicules called "megacanthoxeas". This sponge, however, differs from the other described species in that the megacanthoxeas exist in two distinctly different sizes as opposed to being uniform in size.

Sea Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Tetillidae
Tetillidae is a family of marine sponges. Tetillids are more or less spherical sponges (sometimes referred to as golf ball sponges) which are found commonly in all marine habitats at all depths throughout the world. They are especially common in sedimented habitats. Over a hundred species have been described in ten genera. Reproduction Reproduction in tetillids is quite varied, although free-swimming larvae have not been seen in this group. In some species fertilized eggs are released which settle directly onto the substrate and develop ''in situ''. In other species the eggs develop within the body cavity of the adult sponge and are released as small adult sponges via localized breakdown of the pinacoderm.

Bunaken
Bunaken is an island of 8 km2, part of the Bunaken National Marine Park. Bunaken is located at the northern tip of the island of Sulawesi, Indonesia. It belongs administratively to the municipality of Manado. Scuba diving attracts many visitors to the island. Bunaken National Park extends over an area of 890.65 km2 of which only 3% is terrestrial, including Bunaken Island, as well as the islands of Manado Tua, Mantehage, Nain and Siladen. The waters of Bunaken National Marine Park are up to 1,566 m deep in Manado Bay, with temperatures ranging between 27 and 29 °C. It has a high diversity of - corals, fish, echinoderms or sponges. Notably, 7 of the 8 species of giant clams that occur in the world, occur in Bunaken. It also claims to have seven times more genera of coral than Hawaii, and has more than 70% of all the known fish species of the Indo-Western Pacific. Oceanic currents may explain, in part, why Bunaken National Marine Park has such a high level of b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulawesi
Sulawesi (), also known as Celebes (), is an island in Indonesia. One of the four Greater Sunda Islands, and the world's eleventh-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and New Guinea, Papua are larger in territory, and only Java and Sumatra have larger populations. The landmass of Sulawesi includes four peninsulas: the northern Minahassa Peninsula, Minahasa Peninsula, the East Peninsula, Sulawesi, East Peninsula, the South Peninsula, Sulawesi, South Peninsula, and the Southeast Peninsula, Sulawesi, Southeast Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas, the Tolo Gulf between the East and Southeast peninsulas, and the Bone Gulf between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spicule (sponge)
Spicules are structural elements found in most Sea sponge, sponges. The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. Sponge spicules are made of calcium carbonate or Silicon dioxide, silica. Large spicules visible to the naked eye are referred to as megascleres, while smaller, microscopic ones are termed microscleres. The composition, size, and shape of spicules are major characters in sponge systematics and Taxonomy (biology), taxonomy. Overview Sponges are a species-rich clade of the earliest-diverging (most Basal (phylogenetics), basal) animals. They are distributed globally, with diverse ecologies and functions, and a record spanning at least the entire Phanerozoic. Most sponges produce skeletons formed by spicules, structural elements that develop in a wide variety of sizes and three dimensional shapes. Among the four sub-clades of Porifera, three (Demospongiae, Hexactinelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...

Animals Described In 2007
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
