Figure 4. Grades 10 and 11 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 4. Grades 10 and 11. Adult tunicates are usually sessile (some are detached and roll on the sea bottom), but they begin their lives as mobile, planktonic larvae. The Spiralia are diverse, including annelids and molluscs. Many Platyhelminthes (flatworms) are parasitic or aquatic in freshwater and marine environments, but some, like the one shown here, are terrestrial.
Figure 3 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 3. Divergent representatives of two subsequent grades, able to coordinate movement with contractile muscle cells and bioelectric signalling. These are motile, predatory marine organisms.
Figure 7. Grades 19 and 24 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 7. Grades 19 and 24. The Xiphosura have paired book gills under the opisthosoma (thoracetron). Although the group has a long fossil record, there are only 4 living species (Lamsdell 2020). Scorpions, with paired book lungs, chelicerate pedipalps, and an unusual appendage at the rear of the opisthosoma, are now diverse and successful.
Figure 1 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 1. Hypothetical grades of evolution leading to the Salticidae. The estimated time of origin for some of these grades is shown in millions of years (Ma, millions of years ago). Not all sources agree on this arrangement.
Figure 6. Grades 16 and 17 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 6. Grades 16 and 17. The Onychophora, or velvet worms, are successful predators with many species in terrestrial, mostly tropical habitats. With flexible legs, they resemble giant tardigrades. The Mandibulata is by far the most successful group of animals, including the myrapods and the pancrustaceans; the latter group includes the insects and a diverse array of crustaceans, mostly marine.
Figure 2 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 2. Early grades in the evolution of the Salticidae. Although quite divergent, each of these organisms shares important synapomorphies related to multicellularity and cell differentiation with the jumping spiders.
Figure 5. Grades 12 and 15 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 5. Grades 12 and 15. The Ecdysozoa links nematodes, nematomorphs and arthropods to a common ancestor with the ability to shed a protective trilaminate cuticle as it grew. With panarthropods like this minute, aquatic tardigrade, we see the appearance of paired, segmental appendages.

Data from: Walking like an ant: a quantitative and experimental approach to understanding locomotor mimicry in the jumping spider Myrmarachne formicaria
Protective mimicry, in which a palatable species avoids predation by being mistaken for an unpalatable model, is a remarkable example of adaptive evolution. These complex interactions between mimics, models and predators can explain similarities between organisms beyond the often-mechanistic constraints typically invoked in studies of convergent evolution. However, quantitative studies of protective mimicry typically focus on static traits (e.g. colour and shape) rather than on dynamic traits like locomotion. Here, we use high-speed cameras and behavioural experiments to investigate the role of locomotor behaviour in mimicry by the ant-mimicking jumping spider Myrmarachne formicaria, comparing its movement to that of ants and non-mimicking spiders. Contrary to previous suggestions, we find mimics walk using all eight legs, raising their forelegs like ant antennae only when stationary. Mimics exhibited winding trajectories (typical wavelength = 5–10 body lengths), which resemble the winding patterns of ants specifically engaged in pheromone-trail following, although mimics walked on chemically inert surfaces. Mimics also make characteristically short (approx. 100 ms) pauses. Our analysis suggests that this makes mimics appear ant-like to observers with slow visual systems. Finally, behavioural experiments with predatory spiders yield results consistent with the protective mimicry hypothesis. These findings highlight the importance of dynamic behaviours and observer perception in mimicry.
