In recent decades bioahesives, tissue sealants and hemostatic agents became the favored products to control bleeding and promote tissue healing after surgery. However, many of them have side effects or other problems, including an inability to perform well on wet tissue.
In recent…

Banded Coral Shrimp (Stenopus hispidus)
Fun fact: they’re not shrimps (infraorder Caridea) or prawns (suborder Dendrobranchiata) but they have their own infraorder that is Stenopodidea. The main feature of this infraorder are their long lanky (and sexy) walking legs.

Brown Curryfish Sea Cucumber (Stichopus vastus)
Yellowish brown, creased and somewhat rectangular body with dark harlequin markings and a few short knob-like papillae. Inhabit sandy areas often mixed with sea grasses.
Sea cucumbers from this genus is the one you usually find on luxurious Chinese food. XD

Here’s a cutie that’s more poisonous than a rattlesnake. It’s a kind of puffer called the balloonfish, also called blowfish and globefish. Some balloonfish are among the most poisonous animals on earth, and one of the most deadly kind has enough toxin to kill 30 adult humans! Puffers don’t poison people from bites, though, like rattlesnakes, because the toxin is in the innards, so it’s eating puffers that can be dangerous. There are more than a hundred kinds of puffers in the world, and most are pretty cute, especially when they inflate with water or air to make themselves look bigger than a fish eyeing them for lunch. A predator may also remember that a previously eaten puffer gave it a bad bellyache, and leave other puffers alone.
Sea Cushions - Evolution in a Jiffy
by Emily Underwood
When a small group of sea star larvae got swept away from their parents off the coast of Australia thousands of years ago, they proved more resourceful than Tom Hanks in Cast Away. Rather than befriending a volleyball, the short-legged sea stars—called “cushion stars” for their plump shape—developed the ability to mate with themselves.
Their evolution into live-bearing hermaphrodites is one of the fastest known examples of speciation among marine animals, say the authors of a study published online today in the Proceedings of the Royal Society B. To pinpoint when and where the sea stars broke away from their kin, the team analyzed DNA from the tissue of nearly 400 animals, half belonging to the ancestral species, Cryptasterina pentagona, and half to the new species, C. hystera.
By analyzing the evolutionary relationships between the two species’ DNA sequences, they were able to infer that C. hystera had broken away from the southern range of C. pentagona near the Great Barrier Reef at most 22,000 years ago. By about 6000 years ago, C. hystera had become a distinct species—lightning-quick adaptation, by evolutionary standards.
