“…Marine arthropods fouled by bryozoans vary in surface area by three orders of magnitude (Key et al . , table 10.2). If the relative per cent cover of the host arthropod by the fouling bryozoan is low, then the potential benefit of camouflage is lost.…”

“…Fourth, this approach requires the assumption that post-settlement bryozoan larval mortality is equal among all arthropod basibionts. While on the exoskeleton of the arthropod basibiont, bryozoan larvae and their resulting colonies are affected by differential abrasion from the substrate (Fernandez-Leborans 2010), host grooming (Bauer 1981;Tashman et al 2018), predation (Key et al 2013), food availability (Eggleston 1971) and subaerial exposure (Key et al 1995).…”

“…This coevolutionary diversification would have involved different motile marine hosts and different sessile encrusting marine bryozoans than in this study. Trilobite arthropods, part of the Cambrian Evolutionary Fauna (Sepkoski 1981(Sepkoski , 1984(Sepkoski , 2000, were a common basibiont for stenolaemate bryozoans (Key et al 2010). Nautiloid cephalopods, part of the Palaeozoic Evolutionary Fauna (Sepkoski 1981(Sepkoski , 1984(Sepkoski , 2000, were a common basibiont for stenolaemate bryozoans (Wyse .…”

“…Bryozoans include the post-Palaeozoic sessile marine Gymnolaemata and Stenolaemata; 2 Arthropods and encrusting bryozoans. Though erect bryozoans do occur on fossilized arthropods (Key et al 2010) and many erect forms begin with a small encrusting base, by far the most common growth forms on arthropods are encrusting bryozoans (Key et al 2017). Therefore, the bryozoan colony growth form was classified for each family using the simplified growth form classification of Nelson et al (1988) as modified by Smith & Nelson (1994) and summarized in Smith et al (1998).…”

We hypothesize that the diversification of motile marine arthropods with hard carapaces resulted in a concurrent increase in the diversity of encrusting marine bryozoans whose larvae exploited those substrates through the Mesozoic and Cenozoic. To test this, family‐level data were tabulated from the literature on the post‐Palaeozoic diversity of motile marine arthropod basibionts and sessile marine bryozoan epibionts. We found strong temporal correlation from general to more specific basibiont‐epibiont relationships (i.e. arthropods and bryozoans in general to decapods and encrusting gymnolaemates to robust decapods and encrusting cheilostomes in particular). We compared the diversification of bryozoans to another common group of basibionts (i.e. molluscs) and found weaker correlations. This suggests that the diversification of motile arthropods with hard carapaces (e.g. brachyuran crabs) may have played a role in the diversification of sessile bryozoans (e.g. encrusting cheilostomes) in the post‐Palaeozoic.
