The ability to regenerate amputated limbs and lost body parts is the starfish's most striking adaptation to its dangerous marine environment. After a predator's attack a few species of starfish can regrow almost their entire bodies from just a part of a severed arm. Other species require an i...
adaptationThe reactions of the starfish Asterias amurensis and Patiria pectinifera that live in Vostok Bay at the salinity of 32–33‰ to a salinity decrease were studied under laboratory conditions. The lower limits of the desalination tolerance range of A. amurensis and P. pectinifera were, ...
Starfish also notice the signals of other starfish who are ready to reproduce and they gather in large groups at this time. For a creature without brains or blood, they are pretty interesting as well as beautiful. Except when they turn their stomachs outside their body to catch their prey....
The acquisition of Na+-NQR may therefore represent one of the mechanisms responsible for the adaptation of COT27 to marine environments. With regard to the selective loss of chemotaxis genes, it is very unusual in Spirochaetes; most of the high-quality Spirochaetes genomes mentioned above (...
whose functions range from metabolite transport to immunity14. The coelomocytes phagocytose cell debris and the microorganisms, e.g. microorganisms that invade into the body after injury and autotomy15. Despite this immune system activity, the CF of sea cucumber was reported to harbour unique ...
Outbreaks of corallivorous Crown-of-Thorns Starfish (CoTS, Acanthaster spp.) have caused persistent and widespread loss of coral cover across Indo-Pacific coral reefs. The potential drivers of these outbreaks have been debated for more than 50 years, hin
