Plataforma SINC The Ribbed Mediterranean Limpet is one of the most endangered invertebrates of the Mediterranean Sea and is classed as being in danger of extinction. Researchers at the Spanish National Museum of Natural Sciences have discovered their reproductive strategy, consisting in changing sex from male to female and vice versa, which improves their ability to adapt to changes in their environment. The Ribbed Mediterranean Limpet, Patella ferruginea, shares the unfortunate...

Snail shells coil in response to an lopsided protein gradient across their shell mantles, finds research in BioMed Central's open access journal EvoDevo. In contrast the shell mantle of limpets, whose shells do not coil, have a symmetrical pattern of the protein Decapentaplegic (Dpp). There are many hundreds of different kinds of gastropods (slugs snail and limpets) - second only in number of species to insects. They have adapted to live on land as well as in fresh water and marine...

Below the waterline, about 30% of Hawai'i's marine species are endemic "“ being found only in Hawai'i and nowhere else on Earth "“ one of the highest rates of endemism found worldwide. But where did this diversity of species come from? Hawai'i is famous for its adaptive radiations (the formation of many species with specialized lifestyles from a single...

Think "mass extinction" and you probably envision dinosaurs dropping dead in the long-ago past or exotic tropical creatures being wiped out when their rainforest habitats are decimated. But a major mass extinction took place right here in North America in the first half of the 20th century, when 47 species of mollusk disappeared after the watershed in which they lived was dammed.Now, a population of one of those species"”a freshwater limpet last seen more than 60 years ago and presumed...

By Crawford, Terry J Crawford, Bruce J Abstract: In Rarotonga, Linckia multifora (Lamarck) exists in two forms: a blue gray type that is found on the reef intertidally and a red form that is found subtidally. Both types reproduce asexually by regeneration of autotomized arms, as well as sexually, but the relative potential for sexual reproduction varies greatly between these different sites. In the laboratory, reciprocal crosses of the blue gray intertidal form and the red subtidal form...
