Conspicuous Visual Signals Do Not Coevolve with Increased Body Size in Marine Sea Slugs

Conspicuousness is a key image statistics; feature of aposematic signals, and experimental evidence suggests that pre- nudibranchs; dators avoid conspicuous prey more readily when they exhibit larger body spectral contrast; size and/or pattern elements. Aposematic prey species may therefore evolve visual signalling. a larger body size due to predatory selection pressures, or alternatively, larger prey species may be more likely to evolve aposematic colouration. Therefore, a positive correlation between conspicuousness and body size should exist. Here, we investigated whether there was a phylogenetic correlation between the conspicuousness of animal patterns and body size using an intriguing, understudied model system to examine questions on the evolution of animal signals, namely nudibranchs (opisthobranch mol- luscs). We also used new ways to compare animal patterns quantitatively with their background habitat in terms of intensity variance and spatial frequency power spectra. In studies of aposematism, conspicuousness is usually quantified using the spectral contrast of animal colour patches against its background; however, other components of visual signals, such as pattern, luminance and spectral sensitivities of potential observers, are largely ignored. -

Aceptado el 22-I-2003 ABSTRACT Four species, collected in the Cape Verde Islands, are described as new and assigned to the genus Euthria M. E. Gray, 1830. The new species are compared with other taxa from the Mediterranean Sea and the Cape Verde Archipelago. The genera Euthria , and Buccin - ulum are compared and the significance of the differences between them is discussed, leading to the conclusion that both genera are valid and should be kept separated. RESUMEN Se describen cuatro especies nuevas del género Euthria M. E. Gray, 1830 recogidas en aguas circalitorales del archipiélago de Cabo Verde. Las nuevas especies son compara - das con otros taxones congenéricos existentes en el Mediterráneo y en el propio archip - iélago. Recientemente, el género Euthria, únicamente conocido del Atlántico oriental, ha sido sinonimizado con Buccinulum , que posee especies en el Indo-Pacífico, por lo que se comparan ambos géneros y se discute el valor de las diferencias entre ellos, considerando finalmente que ambos son válidos, y deben mantenerse separados. KEY WORDS: Euthria , Buccinulum , Cape Verde Archipelago, new taxa. PALABRAS CLAVE : Euthria , Buccinulum , Archipiélago de Cabo Verde, nuevos táxones.

About forty Families in all, counting literally hundreds of different species: in scientific lingo – which is absolutely fundamental even if most divers shamefully skip it – they’re highly evolved gastropods (gastro=stomach, pod=foot: critters crawling on their belly), belonging to the Class Opistobranchia (opisto=protruding, branchia=gills: with external gills), ie close relatives of your common land-based, lettuce- eating garden snails.

Gastropoda, Buccinidae), a Reappraisal
Beets, Notes on Buccinulum, a reappraisal, Scripta Geol., 82 (1986) Notes on Buccinulum (Gastropoda, Buccinidae), a reappraisal C. Beets Beets, C. Notes on Buccinulum (Gastropoda, Buccinidae), a reappraisal. — Scripta Geol., 82: 83-100, pis 6-7, Leiden, January 1987 An attempt was made to assemble what is known at present of Buccinulum in the Indo-Western Pacific Region, fossil and Recent, more scope being offered by the discovery of new Miocene fossils from Java and Sumatra, and the recognition of further fossil species from India and Burma. This induced comparisons with, and revisions of some of the fossil and living species occurring in adjacent zoogeographical provinces. The Recent distribution of the subgenus Euthria appears to be much more extensive than when recorded by Wenz (1938-1944), the minimum enlargement encompassing an area stretching from the eastern Indian Ocean to Japan, via the Philippines and Ryukyu Islands. The knowledge of its fossil distribution, in the Indopacific Region long confined to Javanese Eocene, has likewise greatly expanded by discoveries made in Neogene to Quaternary of India, Burma, Indonesia (Sumatra, Java, Madura, and Borneo), the Philippines, New Hebrides, Fiji?, Ryukyu Islands, and Japan. The relevant data were tabulated. New taxa described are: Buccinulum pendopoense and B. sumatrense, both from presumed Preangerian of Sumatra, and B. walleri sedanense from the Rembangian of Java. It is proposed to include Ornopsis, which was described from the Upper Cretaceous of North America, as a subgenus of Buccinulum. It may well be ancestral to Euthria, considering its similarity to certain of the latter's fossil and living species. -
