The Theraphosinae are a large subfamily of Mygalomorphae spiders in the family Theraphosidae found primarily in the Neotropical realm. Genera
Young T. apophysis spiders have pink shading at the end of each leg, which fades with each moult. [4] T. apophysis has an additional stridulating organ on the coxa of the second leg and thinner femora than T. blondi. The male T. apophysis has tibial apophyses (projections) – hence the species name. [3]
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
Therapsida [a] is a clade comprising a major group of eupelycosaurian synapsids that includes mammals and their ancestors and close relatives. Many of the traits today seen as unique to mammals had their origin within early therapsids, including limbs that were oriented more underneath the body, resulting in a more "standing" quadrupedal posture, as opposed to the lower sprawling posture of ...
Cell group B9 is a group of cells located in the pontine tegmentum, ventral to serotonergic group B8. In the nonhuman primate they are found in the ventral part of the superior central nucleus and adjacent structures. [3] In the rodent they have a more lateral location within the medial lemniscus of the pons and dorsal and medial to it., [4] [5]
As the magma develops over time and the crystal content of the magma increases, phase separation is taking place and the liquid phase of the magma is pushed up, driven by its buoyancy as a result of its lower density. Volcanoes, as valves of the open system, provide the path for gas release and magma eruption. The amount of dissolved gases may ...
The Grímsvötn volcano in Iceland is a sub-glacial volcano, located beneath the Vatnajökull ice cap. For a typical sub-glacial eruption, overlying glacial ice is melted by the heat of the volcano below, and the subsequent introduction of meltwater to the volcanic system results in a phreatomagmatic explosion.

Hapalotremus is a genus of South American tarantulas in the Theraphosinae subfamily that was first described by Eugène Louis Simon in 1903. [2] They have red or white Type III urticating (relatively long, thin) hairs, [3] up to 1.2 millimetres (0.047 in), with a fine point and barbs along at least half of the lower part.
