Die mehrfach unterbrochene Kette tertiärer und jüngerer vulkanischer Gesteine, welche Java der Länge nach durchzieht, wird nordwärts und südwärts sowie in den Lücken von tertiären und quartären Ablagerungen eingerahmt ¹). Kreideformation und hoch krystalline Schiefer treten ganz vereinzelt und auf wenige Aufschlüsse beschränkt zutage.

SummaryColour changes in crustaceans are controlled by a secretion originating in the eye‐stalk. The glandular tissue is probably Hanström's sinus gland, although the X‐organ may also be concerned in this function. Retinal pigment migration is similarly regulated by a hormone from the eye‐stalks.

Spectrophotometric Method. The spectrophotometric method [247], described in Sects. 4.2.1 and 7.1.1 for the determination of arsenic in sediments and in fish, is also applicable to the determination of arsenic in crustacea. Recoveries of 5–10 μg arsenic added to a crayfish with a basal arsenic content of 16.8 ≦ 0.5 μg arsenic were between 98 and 100 %.

The Arthropods in their numbers and in their variety of species far exceed all the rest of the animal kingdom put together. Of the animals which live in fresh water a high proportion belong to this phylum. The name ‘Arthropod’ means jointed limbs, the most characteristic feature of the phylum being the fact that the numerous limbs on the body are made ...
