Eunectes murinus, Eunectes cinsine bağlı zehirsiz bir yılan türüdür.^[4][5] Güney Amerika ve Trinidad'da bulunur. En büyük ve en ağır yılanlar listesindedir ve Malayopython reticulatusdan sonra dünyadaki en ağır yılandır.

Yaklaşık 5,21 m (17 ft 1 in) uzunluğa erişebildiğinden dünyadaki en ağır ve uzun yılanlardan biridir.^[6] Dişiler erkeklerden genel olarak daha büyüktür. Tipik yetişkin dişi 5 m (16 ft 5 in) uzunluğa erişebilirken, ortalama 4,6 m (15 ft 1 in) uzunluğundadır. Erkekler ortalama 3 m (9 ft 10 in) uzunluğundadır.^[7][8][9] Ağırlıklarıyla ilgili araştırmalar daha az olsa da tipik yetişkin yaklaşık 30-80 kg (66-176 lb) arasındadır.^[10][11][12]

Türle ilgili 11-12 m (35-40 ft) uzunluğa veya daha da uzun oldukları bilinse de fiziki deliller veya müzelerde bulunmamasından dolayı kayıtlara geçen bulunmamaktadır.^[13] En ağır ve en uzun olan tü, 1000'den fazla Eunectes türü incelemiş olan Dr. Jesús Antonio Rivas^[14] tarafından onaylanan 5,21 m (17 ft 1 in) uzunluğunda ve 97,5 kg (214 lb 15 oz) ağırlığındaki dişidir.^[6]
