The birds have realized to push bricks off the bin covers utilizing brute power, whereas sneakers jammed by a bin’s handles are a greater deterrent. However these trash thieves might ultimately discover a approach round that blockade too.

The Caribbean sponges are continuously oozing mucus like a toddler with a runny nostril. Seems to be like somebody might use a tissue.

The Caribbean tube sponge (Aplysina archeri) makes use of contractions — referred to as “sneezes” — to assist eject mucus from its pores, or ostia. Because the time-lapse video zooms in nearer, it’s attainable to see tiny specks of particles floating out of those pores and touring alongside a “mucus freeway” the place they accumulate into stringy clumps of goo floating above the floor of the sponge.
