Goyenia facts for kids
Goyenia is a special group of spiders. These spiders are known as intertidal spiders. This means they live in areas where the land meets the sea, like beaches or rocky shores. They were first described by a scientist named Raymond Robert Forster in 1970. All the Goyenia spiders live in New Zealand.

What is a Goyenia Spider?
Goyenia is a genus of spiders. A genus is like a family group for animals that are very similar. These spiders are part of the Desidae family, which includes many types of spiders that live near water. Goyenia spiders are quite unique because they can handle living in places that are sometimes covered by ocean water and sometimes dry.
Where Goyenia Spiders Live
All ten known species of Goyenia spiders are found only in New Zealand. This makes them endemic to New Zealand, meaning they don't naturally live anywhere else in the world. They prefer the coastal areas, living in the space between the high and low tide marks. This habitat is called the intertidal zone.
Who Discovered Goyenia?
The scientist who first studied and named Goyenia spiders was Raymond Robert Forster. He was a famous arachnologist, a person who studies spiders and other creatures like them. He described the first Goyenia species in 1970. His work helped us learn about these amazing spiders.
Species of Goyenia
As of May 2019, there are ten different species of Goyenia spiders. Each one was identified by Raymond Robert Forster in 1970. All these species live in New Zealand.
- Goyenia electa (Forster, 1970) – This is the main type of Goyenia spider.
- Goyenia fresa (Forster, 1970)
- Goyenia gratiosa (Forster, 1970)
- Goyenia lucrosa (Forster, 1970)
- Goyenia marplesi (Forster, 1970)
- Goyenia multidentata (Forster, 1970)
- Goyenia ornata (Forster, 1970)
- Goyenia sana (Forster, 1970)
- Goyenia scitula (Forster, 1970)
- Goyenia sylvatica (Forster, 1970)
Life in the Intertidal Zone
Living in the intertidal zone is tough for any animal. Goyenia spiders have special ways to survive. When the tide comes in, their homes might be underwater. They need to find shelter or hold on tight to avoid being washed away. When the tide goes out, they can hunt for food.
What Do They Eat?
Like most spiders, Goyenia spiders are predators. They likely eat small insects and other tiny creatures that live in their coastal habitat. They might build webs to catch their prey, or they might actively hunt for food. Their diet helps keep the balance in their ecosystem.
How They Survive Flooding
Spiders that live in intertidal zones often have adaptations to deal with water. Some can trap air bubbles to breathe underwater for a short time. Others might seal themselves in silk retreats that keep water out. Goyenia spiders have developed their own ways to survive the changing tides.
Importance of Goyenia Spiders
Every creature, even a small spider, plays a role in its environment. Goyenia spiders are part of the food web in New Zealand's coastal areas. They help control insect populations and also serve as food for other animals. Studying them helps scientists understand how life adapts to extreme environments.
