 Principles of Systematics, Module 96, Identifications of Family Salty-Seed Salty seeds are arachnids that belong to phylum Arthropoda. They are journalist predators. They consume insect pests which are present in agro-ecosystems all over the world. They are strictly carnivorous. According to word spider catalog, there are more than 600 genera of salt acids. Salt acid family is considered largest family of spiders and it contributes more than 13% of all species of spiders. They are also known as jumping spiders. They have ability to jump. Salty seeds are called jumping spiders because they jump from their place to capture their prey. And they jump on their prey. All the jumping spiders have four pairs of eyes. They have four pairs of eyes and their eye pattern is unique. If we look closely at the picture in this slide, the front eyes are very large. They are prominent. They are like the headlights of a car. This is the typical character of this family. We can easily recognize the spiders of this family. Salty seeds are highly advanced. If we compare all the members of this family, their vision is very advanced. They use this vision for courtship, hunting and navigation. If we look closely at the legs of Salty seed spiders, they do not have prominent spines on their legs. If we look at the other spiders like the Oxford family, their legs have conspicuous spines on them. But Salty seed families do not have prominent spines on their legs. If we look closely at the legs of Salty seeds, their front pairs are larger as compared to the legs which are present on the posterior side. Similarly, if we look closely at the spines on their legs, they do not have prominent spines on their legs. But if we look closely at the spines on their legs, they have prominent spines on their legs. This is the difference between Salty seed family and Thomy seed family. After that, the front legs of Salty seed spines are comparatively larger. Their size is bigger and the back legs are comparatively smaller. The legs of Salty seed family do not have prominent spines on their legs. But the legs of Thomy seed family do have prominent spines on their legs. After that, if we look at the size of the family members, they can be from 1 mm to 25 mm. This means that they have a lot of variations in their size. Apart from that, the largest member of this family, the largest species is the Highless Gigantius. After that, when the members of the Salty seed family attack their prey, they attach themselves to the substrate where they are located. After that, they jump on their prey. Now, why do they attach themselves to the substrate? Because if their attack fails and they are in the air, then they come back to their place through the substrate. If we talk about the strength of the muscles in their legs, then their legs are not very strong or their muscles are very powerful. Now, when they jump to attack on the prey, then what do they depend on? Usually, they increase the blood pressure in their legs. When their legs increase in blood pressure, then a force is generated from it which helps them to jump and attack on their prey and ultimately capture the prey. If their attack fails, then they attach their body through the substrate. That is why they come back to their place.
