Theraphosa apophysis generally resembles Theraphosa blondi, and reaches a similar size. [3] Young T. apophysis spiders have pink shading at the end of each leg, which fades with each moult. [4]
This is because most magma from which igneous rock solidifies is produced by partial melting of a mixture of different minerals. [4] At first the mixed melt slowly cools deep in the crust. The magma begins crystallizing, the highest melting point minerals closest to the overall composition first, in a process called fractional crystallization .
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity, the production, intrusion and extrusion of magma or lava. Volcanism is the surface expression of magmatism.
The tholeiitic magma series (/ ˌ θ oʊ l eɪ ˈ ɪ t ɪ k /) is one of two main magma series in subalkaline igneous rocks, the other being the calc-alkaline series. A magma series is a chemically distinct range of magma compositions that describes the evolution of a mafic magma into a more evolved, silica rich end member.
A further control on the morphology and characteristics of a deposit is the water to magma ratio. It is considered that the products of phreatomagmatic eruptions are fine grained and poorly sorted where the magma/water ratio is high, but when there is a lower magma/water ratio the deposits may be coarser and better sorted.

Bistriopelma has two distinctive patches of Type III urticating setae, which are located dorsolaterally on the abdomen, each with a long stripe of thicker setae, which runs diagonally to the longitudinal body axis.
Hemirrhagus is a genus of Mexican tarantulas that was first described by Eugène Louis Simon in 1903. [3] It is considered a senior synonym of Spelopelma. [2] Species of the genus Hemirrhagus are 5 to 12 cm long, usually black in colour, the urticating hairs on the opisthosoma are arranged in one dorsomedian patch, two dorsal paramedian patches, or two lateral patches.
