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.
