The 20 extant species of Suina are split between the Suidae family, containing 17 extant species belonging to six genera, and the Tayassuidae family, containing three species in three genera. All extant suids are members of the Suinae subfamily; extinct species have also been placed into Suinae as well as other subfamilies. Dozens of extinct ...
The suborder Suina consists of 21 extant species in nine genera. These are split between the Suidae family, containing 18 species belonging to 6 genera, and the Tayassuidae family, containing 3 species in 3 genera. This does not include hybrid species such as boar–pig hybrids or extinct prehistoric species.
Suids are weaned at around three months, and become sexually mature at 18 months. In practice, however, male suids are unlikely to gain access to sows in the wild until they have reached their full physical size, at around four years of age. In all species, the male is significantly larger than the female, and possesses more prominent tusks. [3]
The Invasive Species Specialist Group lists feral pigs on the list of the world's 100 worst invasive species and says: [47] Feral pigs like other introduced mammals are major drivers of extinction and ecosystem change. They have been introduced into many parts of the world, and will damage crops and home gardens as well as potentially spreading ...

Celebochoerus cagayanensis is an extinct species of suid in the genus Celebochoerus. The first fossil specimen was discovered in 2016 in the Philippines. [1] It differs from the Sulawesi species Celebochoerus heekereni in that it has mesial and distal enamel bands on its upper canines. [1] It also has huge upper tusks. [2]
These lists of synapsids collectively include every genus that has ever been included in the clade Synapsida- the mammals and their evolutionary precursors. The lists includes accepted genera along with those now considered invalid, doubtful (nomina dubia), not formally published (nomina nuda), junior synonyms of more established names, as well as genera that are no longer considered synapsids.
The image was published in the 1993 book European Seashells by Guido T. Poppe and Goto Yoshihiro, where it was identified as Architeuthis dux, the giant squid, and said to have been taken in the North Atlantic. [12] [clarification needed] If true, this image would represent the earliest known photograph of a live giant squid. [11]
