![]() They are small a nd nocturnal mammals, basically insectivores, that live in the West Indies. In the following video a lazy lori is disturbed and hisses like a snake while trying to bite: SOLENODON OR ALMIQUI It is believed that slow lorises even have converged evolutionarily with cobras, for his defensive behavior when threatened, whistling and raising his arms around his head. Secretion is similar to the allergen Fel d 1 which is in the domestic cat and cause allergies in humans (Hagey et al., 2006 Krane et al., 2003). Toxins are polypeptides ( generated when glandular secretion is mixed with saliva) and an unidentified steroid. Exudate from glands, as in echidnas, can also give olfactory information of range and territory between individuals of loris (Hagey et al., 2007). Being poisonous, unusual among primates, can help counteract the disadvantages of its slow movements. The poison also serves as protection for the young, they are licked by their parents and the poisonous secretion is distributed throughout the coat. In this case the poison is used as a defense against predators, causing them pain, inflammation, necrosis (cell death) in the area of the bite, hematuria (blood in urine) or in some cases anaphylactic shock (allergic reaction) which can lead to death, even in humans (some are threatened by the illegal pet trade and traditional Chinese medicine). They possess poison glands on the elbows ( brachial gland), and poison their body with arms and tongue, which can also join saliva and be transmitted by bitting. The slow lorises (Nycticebus) living in Southeast Asia, are the only poisonous primate. They are nocturnal, arboreal and feed primarily on insects, vegetables and fruits. SLOW LORISĪs we saw in a previous post, lorises are primates in the prosimians suborder. The substances are used to mark their territory, according to the recent studies. Like the platypus, they also have spurs behind the knees, but their secretions are not poisonous. They are mainly insectivores specializing in ants and termites. The family consists of four species, with the common characteristic of having the body covered with dense hair and spines. ![]() Photo de Tony Britt-LewisĮchidnas (family Tachyglossidae) complete the order of monotremes with the platypus consequently they are also oviparous. Short-beake echidna (Tachyglossus aculeatus). Understanding how these toxins act it has special interest because they cause a lasting and severe pain it may open new chances in the synthesis of analgesic drugs. These are globular proteins, small and compacted, involved in the activation of pain receptors. They are like the defensins (DLP, defensin-like proteins). Toxins are four proteins, three of which are unique to the platypus. This poison can kill small animals, including dogs, and cause severe pain and swelling in humans. The male uses it mainly to defend their territory and establish their dominance during the mating season, although if it is bothered also uses it as a defense. P latypuses have a spur on the hind legs, which only in the case of males, release poison produced by femoral glands (located in the leg). They are distributed by Australia, Tasmania and New Guinea. Monotremes are the only mammals that lay eggs, but his body is covered with hair and the young are fed with breast milk. Some evolutionary biologists refer to them as the “missing link” between reptiles and mammals, as they have characteristics of both groups. ![]() ![]() They belong to the order monotremes, which means “one hole ” in reference to the cloaca, the end of the digestive and reproductive systems. With a peak like a duck and oviparous (laying eggs), when it was discovered some scientists thought it was a fraud. ![]() The platypus ( Ornithorhynchus anatinus) is the most famous among the poisonous mammals, and not just for this feature. as venomous animals par excellence, but did you know that there are poisonous mammals? In this article we will discover who are they and the nature and use of their poisons. We usually associate snakes, spiders, jellyfish, etc. ![]()
