  First documented cases of invertebrate predation by greater grisons (Galictis vittata) Abstract  We report the first documented predation of invertebrates by greater grisons (Galictis vittata) based on camera-trap footage from a mineral lick in Southeastern Peru. Two adult individuals were recorded capturing and consuming large arachnids, likely whip spiders (Amblypygi), from a natural cavity. One grison visibly removed and discarded part of the prey prior to ingestion, suggesting selective handling to reduce risk from defensive structures. These observations extend the known cavity-focused foraging behavior of G. vittata and indicate that amblypygids may represent an underreported but regular prey item in tropical habitats.

The genome sequence of the spider, Parasteatoda lunata (Clerck, 1757)

Abstract

We present a genome assembly from an individual female Parasteatoda lunata (spider; Arthropoda; Arachnida; Araneae; Theridiidae). The genome sequence is 1,411.4 megabases in span. Most of the assembly is scaffolded into 12 chromosomal, including the X1 and X2 sex chromosomes. The mitochondrial genome has also been assembled and is 14.29 kilobases in length.
