Муравей-пулемет / Machine-gun ant



В Южной Америке открыты уникальные муравьи - у их солдат одна голова и два туловища. Они охотятся следующим образом: тихонько проникают в термитник, заползают в набитую термитами гнездовую камеру и внезапно начинают крутиться вокруг своей оси, "стреляя" кислотой во все стороны из обоих брюшек. Пришедшие по их следу рабочие муравьи собирают отравленных кислотой термитов и уносят в муравейник.

Unusual ants have been discovered in South America. Their soldiers have one head and two bodies. To hunt, they sneak into termite nests, crawl into a nest chamber filled with termites, and suddenly start spinning, spraying acid from both abdomens in all directions. Workers follow their trail to retrieve acid-poisoned termites and carry them to the anthill.


На самом деле на фотке хищный паук Aphantochilus rogersi с добычей (паук слева, добыча справа). Этот паук кормится муравьями Cephalotes atratus, устраивая засады вдоль муравьиных троп. Убив муравья, паук долго носит его, как щит, чтобы остальные муравьи принимали его за рабочего, несущего труп товарища. Паук похож на добычу и запахом, и гладким панцирем, и внешностью - таким образом он обманывает и подслеповатых муравьев, и птиц, которые не любят клевать жестких кусачих муравьев, но всегда рады съесть сочного паучка.

Actually, the photo shows a crab spider Aphantochilus rogersi with its prey (spider is on the left). This spider hunts turtle ants Cephalotes atratus by ambushing them on their trails. After killing an ant, the spider carries it around for a while, pretending to be a worker carrying a deceased comrade. By mimicking the ants' smell, texture and visual appearance, the spider fools not only ants, but also birds which don't like hard-shelled, feisty ants but wouldn't miss a juicy spider.
