Detailed explanation-1: -There is maternal care in all species of mammals, and while 95% of species exhibit female-only care, in only 5% biparental care is present. Thus, there are no known cases of male-only care in mammals.

Detailed explanation-2: -Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
