Mantis shrimp. Called "sea locusts" by ancient Assyrians, "prawn killers" in Australia and now sometimes referred to as "thumb splitters" – because of the animal's ability to inflict painful gashes if handled incautiously[4] – mantis shrimp sport powerful claws that they use to attack and kill prey by spearing, stunning, or dismemberment.

Mantis shrimp

Although it only happens rarely, some larger species of mantis shrimp are capable of breaking through aquarium glass with a single strike from this weapon.[5] Ecology[edit] These aggressive and typically solitary sea creatures spend most of their time hiding in rock formations or burrowing intricate passageways in the sea bed. They either wait for prey to chance upon them or, unlike most crustaceans, at times they hunt, chase, and kill prey. They rarely exit their homes except to feed and relocate, and can be diurnal, nocturnal, or crepuscular, depending on the species.

Amazing jellyfish lake

Eil Malk is part of the Rock Islands, a group of small, rocky, mostly uninhabited islands in Palau’s Southern Lagoon, between Koror and Peleliu. It is notable for the millions of golden jellyfish which migrate horizontally across the lake daily. photo source Jellyfish Lake is connected to the ocean through fissures and tunnels in the limestone of ancient Miocene reef.

However the lake is sufficiently isolated and the conditions are different enough that the diversity of species in the lake is greatly reduced from the nearby lagoon. Photo source Two species of scyphozoan jellyfish live in Jellyfish Lake, moon jellyfish and the golden jellyfish. photo source The golden jellyfish are most closely related to the spotted jellyfish that inhabit the nearby lagoons. Photo source The moon jellyfish were identified as Aurelia aurita by Hamner. Photo source photo source photo source photo source.

The whale's thought to be a few weeks old and was spotted by a local man. He said: "I couldn't believe my eyes, and I just grabbed my camera. Then the white calf approached my boat, seeming to want to check us out. " White whales are rare - the reef's rep says there are only 10-15 among the 10,000-15,000 humpback whales living along Australia's east coast.

UC Berkeley Press Release Octopuses occasionally stroll around on two arms, UC Berkeley biologists report By Robert Sanders, Media Relations | 24 March 2005 BERKELEY – Two species of tropical octopus have evolved a neat trick to avoid predators - they lift up six of their arms and walk backward on the other two.

3.24.2005 - Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

This first report of bipedal behavior in octopuses, written by University of California, Berkeley, researchers, will be published in the March 25 issue of Science. When walking, these octopuses use the outer halves of their two back arms like tank treads, alternately laying down a sucker edge and rolling it along the ground. UC Berkeley graduate student Crissy Huffard clocked the two-legged speed of one coconut octopus at two and a half inches per second, while a second individual zoomed along, backwards, at five and a half inches per second.

Not so when walking. "This bipedal behavior allows them to get away and remain cryptic," said Huffard.
