Answer: Nearly all spiders subdue their prey by injecting venom through their fangs, which operate much like a pair of hypodermic needles. Besides the paralytic action of the venom compounds, the spider regurgitates digestive fluids onto the prey to digest it, working more or less like a meat tenderizer. Once the prey begins to liquefy, the spider uses its jaws and pedipalps to further masticate its meal. The âmeat ballâ is then slowly imbibed by the mouthparts, taken in mostly in liquid form. Spiders in the obscure family Uloboridae do not possess venom glands, but the rest of the feeding process remains the same.
Color patterns on the common dolphin are the most elaborate of any cetacean. The back is dark gray-to-black from the top of the head to the tail dipping to a V on the sides below the dorsal fin. The flanks are light gray behind the dorsal fin and yellowish-tan forward of the dorsal fin, forming an hourglass pattern. Its belly is white.
The other three species -- the striped dolphin, pantropical spotted dolphin and Atlantic spotted dolphin -- are named for their distinctive body markings. A Touch of White Five of the six dolphin species in genus Lagenorhynchus occur in the Atlantic Ocean, where they inhabit polar to temperate waters. Often called white-sided dolphins, species of this genus have a defining short beak. The white-beaked dolphin, the largest species, is found in subpolar waters in the northern Atlantic. The Atlantic white-sided dolphin also inhabits the northern Atlantic Ocean but in temperate waters. Also in this genus are dusky dolphins, named for their dark backs. They are found along the Atlantic coast of South Africa and around the Falkland Islands of South America, where their range overlaps with that of Peale's dolphins, another Lagenorhynchus species.
