Brief SummaryRead full entry
BiologyThe breeding season generally begins in May and although females normally dig hole-nests in the wild, they are capable of building mound-nests under certain conditions; the average clutch size is 30 - 40 eggs (6). In the wild, individuals can interbreed with the American crocodile (Crocodylus acutus) whose breeding season overlaps with that of the Cuban crocodile (6). This hybridisation appears to be natural but may pose a threat to the genetic purity of this species if population numbers fall. The changing nesting strategies may reflect evidence of hybridisation (5). Cuban crocodiles have broad back teeth that are adapted to crushing turtle shells, which enables these crocodiles to get to their main source of food (6). Fish and mammals are also consumed and historically this species appears to have preyed on the, now extinct, giant sloth (6). Possessing strong hind legs, this crocodilian is particularly agile on land, able to move quickly and leap into the air (6).
