After a male courts a female and mates with her, his only other job is to guard her against the sperm of rival males.īut this might not be the case for some squid species. “Usually, the only thing the male does before and after mating is mate guarding,” says Eduardo Sampaio at the University of Lisbon in Portugal. Typically, female cephalopods are left to care for their eggs alone. The cephalopods include the largest living as well as the largest extinct molluscs: ammonite shells range to over 2 m across and body sizes of living squid. The smallest known cephalopod is the Thai bobtail squid (Idiosepius. Octopuses, squids and their cephalopod cousins are famous as brainy, inquisitive and complex animals with many arms, strong suckers and great escape acts. ![]() But bigfin reef squid might be the exception to this rule, as they have now been seen investigating potential nest sites to make sure they are safe before their female counterparts lay eggs. Cephalopods (sef-ah-loh-pods) are a large class of animals in the phylum Mollusca. While they may not be as diverse a group as other molluscs or as the bony fishes in terms of number of species (about 600 cephalopod. Squid are part of the class Cephalopoda (meaning head-footed), a group that also includes the octopus, cuttlefish and nautilus. Male cephalopods, such as squids and octopuses, aren’t known for their parenting due to the fact that they often die soon after mating. Fossils of cephalopods (sef-al-oh-pods) have been found in rocks of many ages, and numerous representatives are alive today. The standard for good cephalopod fathers might be a pretty low bar, but bigfin reef squid swim right over it. ![]()
