Cet ours polaire se tient sur une banquise fragilisée dans l’Arctique. Avec le changement climatique, la glace de mer fond plus tôt et se reforme plus tard. Les ours polaires dépendent de cette glace pour se déplacer, chasser et survivre. À mesure que leur habitat se réduit, ils sont contraints de parcourir de plus longues distances et de passer davantage de temps dans l’eau, au prix d’une dépense énergétique accrue. Cette scène illustre les conséquences directes du changement climatique sur les

Limaria fragilis, also known as the fragile file clam, is known for its delicate and translucent shell that is often so fragile it breaks easily. Found in deeper, colder waters, this clam uses its vibrant orange or yellow mantle to attract plankton, which it feeds on. Its shell is fragile yet helps it blend with the seafloor, making it an expert at camouflage despite its delicate structure. #clam #fileclam #ocean | Critter Hunter

Found on tropical reefs in the Indo-Pacific, the electric file clam has soft tissues which flash light like a disco ball. For years scientists believed the light was generated by chemical reactions known as bioluminescence, but recently scientists worked out the display actually comes from a rapid change from red to white tissue. The white (silica) side reflects 85 to 90 percent of all white light when underwater. Dark and reflective sides are exposed at a rate of 2 times per second, creating th

LUMBRICALS are small muscles that are located in the palm of the hand. They attach from a flexor tendon in the palm, but then move to the dorsal (backside) of the hand to insert into a structure called the extensor expansion. This attachment from the front to the back of the hand allows the unique function of these muscles, which is to flex one joint (the MP joint), but then to extend the others (the IP joints). . . #instituteofhumananatomy #anatomy #anatomylab #anatomyclass #learnanatomy #learn
