living longer than 100 years (Drew et al., 2013), a life span that would allow them to reach a considerable size, provide further support for the large terrestrial crabs Mego call kepi reflecting a population of Birgus . Colours described by eye-witnesses also match the coconut crab, which occurs in two

prehistoric creatures fill the bookshelves at an almost alarming rate, it is certainly good to see a new publication devoted entirely to fossils of invertebrates, which far outnumber those of vertebrates anyway! The present book sets out to ‘highlight the appreciation of fossils as the remains of once living

process of niche construction, thus handing down a substantially different shell as an ecological inheritance (Laidre, 2012a; see also Odling-Smee et al., 2003 for a general review of niche construction). These remodeled shells appear to be better suited for crabs’ life on land, strongly raising a crab

yield recorded during the year y; a = 3 years and k = 3/K or longevity, which in this case equals 13 years; this value is found by considering that a reasonable life expectancy is when 95% of the population reaches 95% of L, the asymptotic length; thus, by making L = 0.95L in the Von Bertalanffy growth
