Venomous Animals Honor

Nature Study

Requirements

1. What are venomous animals?

   Answer: You define venomous animals as those that produce venom (a toxin) and have a special apparatus to inoculate that substance into another living being, such as fangs (snakes), a stinger (scorpions, bees), or bristles (caterpillars). They actively inject the venom into the victim. — They differ from passively poisonous animals (which poison only when touched or eaten, like toads). The technical definition is given by the Butantan Institute: venomous = actively inoculates; poisonous = passively transfers.

2. Find out the number of accidents caused by venomous animals in your country or region in the last year (if that data is not available, use the most recent year available).

   Answer: You research official sources such as the Ministry of Health (SINAN), the Butantan Institute, or State Health Departments. In Brazil, an average of 200 thousand accidents are recorded per year, of which about 30 thousand are from snakes, 150 thousand from scorpions, and 20 thousand from spiders. — The Notifiable Diseases Information System (SINAN) is the official Brazilian source. Scorpion accidents grew 5x since 2000 because of disorderly urbanization — Tityus serrulatus adapts well to large cities and buildings.

3. Choose and present the following characteristics of 2 venomous animals:
   • Habitat
   • Feeding
   • Harm caused to humans
   • Form of prevention

   Answer: You present two examples: 1) Jararaca — habitat in forests and rural areas, feeds on rodents and small animals, causes hemorrhage and necrosis through its venom; prevent by using boots and gloves. 2) Yellow scorpion — urban habitat, feeds on insects, causes intense pain and arrhythmia. — Both are responsible for more than 80% of venomous animal accidents in Brazil. The scorpion Tityus serrulatus is one of the most dangerous because it causes arrhythmia in children. The jararaca causes about 90% of snakebite accidents in Brazil.

4. Name at least three venomous animals in each of the Classes below:
   • Reptiles
   • Insects
   • Arachnids

   Answer: Três animais peçonhentos em cada classe: 1) Répteis: (a) jararaca; (b) cascavel; (c) coral-verdadeira. 2) Insetos: (a) abelha; (b) vespa (marimbondo); (c) formiga lava-pé (Solenopsis). 3) Aracnídeos: (a) escorpião-amarelo (Tityus serrulatus); (b) viúva-negra (Latrodectus); (c) armadeira (Phoneutria). Cada um possui peçonha própria e um aparato específico para inoculá-la (presas, ferrão ou quelíceras). — The true coral snake (Micrurus) has the most potent neurotoxic venom in Brazil. Phoneutria (the wandering spider) is considered the most venomous spider in the world according to the Guinness Book — but it rarely kills healthy adults when antivenom is available.

5. Know how venomous animals are important to the balance of the ecosystem.

   Answer: You explain that venomous animals control prey populations (rodents, insects), preventing pests; they serve as food for predators (birds, mammals); and their venoms are a source of important medicines for humans. Without them, the food chain becomes unbalanced. — Snakes eliminate up to 1,000 rats/year per individual, preventing diseases and agricultural losses. The venom of the jararaca gave rise to captopril (1981), a medication for hypertension still used by more than 40 million people worldwide in treatments today.

6. Learn 4 ways to protect yourself against venomous animals found in homes, businesses, or campsites.

   Answer: You learn: 1) seal cracks in walls and drains; 2) shake out clothes, shoes, and bedding before use; 3) keep the yard clean, free of debris or tall grass; 4) wear high boots and gloves in brushy areas. Window screens are extra protection. — These measures reduce accidents with scorpions and spiders in homes by up to 80%, according to the Butantan Institute. The accumulation of debris creates ideal shelter for scorpions — a single cleanup can eliminate dozens of specimens already lodged there.

7. Do venomous animals generally attack out of malice or in self-defense?

   Answer: You answer that venomous animals attack in self-defense, never out of malice. They inoculate venom only when they feel threatened, stepped on, or cornered. If they go unnoticed, they do not attack — they prefer to flee or remain still. — Animals do not have moral conscience like humans — they act on survival instinct. Studies by the Butantan Institute show that more than 90% of snakebite accidents occur when a person steps on or tries to handle the snake without realizing it.

8. Learn the first aid that should be given to victims of venomous animal bites and stings.

   Answer: You calm the victim, keep the affected limb at rest (below heart level), wash the area with soap and water, remove rings or tight objects, note the time of the accident, identify the animal if possible, and take the victim to the hospital as quickly as possible for antivenom treatment. — PROHIBITED procedures: do not apply a tourniquet, do not cut or suck the wound, do not give alcoholic drinks or offer kerosene. These myths worsen the condition. The decisive factor is the time until the antivenom — the sooner, the better the prognosis for recovery.

9. What is serum therapy (antivenom treatment)?

   Answer: You define serum therapy as the medical treatment that administers antivenom serum (ready-made antibodies against the venom) to the victim to neutralize the toxin already circulating in the body. It is the only effective treatment against severe bites and stings and must be performed in a hospital. — The antivenom serum was invented by Vital Brazil in 1901, at the Butantan Institute. He extracted small doses of venom into horses, waited for them to produce antibodies, and purified those antibodies as serum — a method still used worldwide today.

10. Know which animal bite or sting each type of antivenom below is used for:
    • Anti-bothropic
    • Anti-crotalic
    • Anti-bothropic-lachetic
    • Anti-elapidic
    • Anti-arachnidic
    • Anti-scorpionic
    • Anti-lonomic

    Answer: 1) Anti-bothropic: jararaca bite (genus Bothrops). 2) Anti-crotalic: rattlesnake bite (genus Crotalus). 3) Anti-bothropic-lachetic: jararaca bite (Bothrops) and bushmaster bite (Lachesis). 4) Anti-elapidic: true coral snake bite (genus Micrurus). 5) Anti-arachnidic: bites of venomous spiders, such as the wandering spider (Phoneutria) and the brown recluse (Loxosceles), and also of scorpions. 6) Anti-scorpionic: scorpion sting (genus Tityus). 7) Anti-lonomic: contact with the caterpillars of the genus Lonomia. — Brazil produces all of these antivenoms free of charge at the Butantan Institute and at FUNED. The anti-lonomic antivenom is exclusively Brazilian — Lonomia obliqua caused so many serious accidents in the south of the country in the 1990s that it prompted specific research and the creation of its own antivenom.

11. Carry out at least 1 of the activities below:
    • Visit a zoo or research facility where you can observe venomous animals and present a report.
    • With the guidance of your leader, identify at least 10 venomous animals and present a list with: scientific name, common name, photo, and place of origin.

    Answer: You choose one of the practical options: 1) visit a zoo or research center that houses venomous animals and write a report on the visit; 2) with the leader's guidance, identify at least 10 venomous animals and compile a list with scientific name, common name, photo, and place of origin. — The practical activity consolidates the Pathfinder's theoretical learning. The Butantan Institute (SP) and Vital Brazil (RJ) host guided visits with professionals who explain safe handling — a unique experience for those completing the requirement.

12. Find out at least 2 venomous animals mentioned in the Bible.

    Answer: Venomous animals mentioned in the Bible: 1) Serpent — appears in Genesis 3:1-15 (in Eden) and in Numbers 21:6-9 (the fiery serpents in the desert, and the bronze serpent); 2) Scorpion — mentioned in Luke 10:19 ('I give you authority to tread on serpents and scorpions') and in Revelation 9:5,10 (torment similar to a scorpion's sting); 3) Viper/asp — mentioned in Acts 28:3-6 (the viper that bit Paul in Malta) and in Psalm 91:13. — The Bible was written in a region with abundant venomous fauna (the Middle East). Serpents appear as a symbol of cunning and temptation; scorpions represent pain and judgment. Ezekiel 2:6 also mentions scorpions in a prophetic context.
