Phoneutria fera

Scientific Classification

Physical Description and Identification

Adults

Size: 1.7 – 4.8 cm

Color: Their body and legs are light brown, with red mouthparts.

Other Characteristic Features: Similar to others in its genus, they will raise their front limbs in an aggressive stance to warn enemies.

Eggs

After mating, the female will lay her eggs and cover them in a liquid which will solidify to form a gelatinous mass. The mother will then encase them in a sac made of silk.

Females may lay over 1000 eggs at a time.

Spiderlings

Initially, the larvae do not show much mobility after hatching. Slowly over time, they will develop hair, spines, and claws. Eventually, they become capable of movement. And after undergoing a few molts, they begin to resemble the adults.

The Web

Since they capture prey by wandering about and ambushing them, these spiders do not construct elaborate webbing to catch their food.

Is the Phoneutria fera Venomous

The venom of this spider is quite deadly and medically significant, having caused a few deaths before anti-venom was developed. However, fatal bites are rare nowadays, as the spider’s fangs aren’t large enough to inject vast quantities of venom and treatments are more widespread.
