Question: What is the maximum length of the species that is known to prey on the crossback stingaree? Passage:The broadnose sevengill shark (Notorynchus cepedianus) is known to prey on the crossback stingaree. When threatened, this ray raises its tail warningly above its body in a scorpion-like fashion. Parasites documented from this species include a tapeworm in the genus Acanthobothrium, and the monogenean Calicotyle urolophi. Like other stingrays, the crossback stingaree is aplacental viviparous: when the developing embryos exhaust their supply of yolk, their mother provisions them with nutrient-rich histotroph ("uterine milk") through specialized extensions of the uterine epithelium called "trophonemata". Females produce litters of 1–4 pups every other year. Embryonic development proceeds rapidly over a six-month period, though the total gestation period may be much longer if there is a period of dormancy for the eggs after fertilization, as has been reported in other stingarees. Off Tasmania, large estuaries such as at the mouth of the River Derwent serve as nursery areas.

question:
Question: What films did Ron Perlman work on the year Sklenar was cast in the film Indigo Valley? Passage:He was then cast as Edward Mapplethorpe in the 2018 biographical drama film Mapplethorpe, which follows the life of New York photographer Robert Mapplethorpe. It screened at Tribeca Film Festival in 2018 where it was named a Runner-up in the U.S. Narrative Competition section. Sklenar received positive critical acclaim from multiple media outlets for his performance in Mapplethorpe, including from Boy Culture who praised him for "[having] maximum impact in [his] psychologically charged scenes with [Matt] Smith" and Screen Daily who said:"As the brother and photographer Edward Mapplethorpe, who Robert [Mapplethorpe] forced to change his name, Brandon Sklenar is a fragile mix of awe and fear." He appeared in the 2018 biographical drama film Vice, opposite Amy Adams, Steve Carell, Christian Bale and Sam Rockwell. The film explores the life of politician Dick Cheney and is directed by Academy Award-winner Adam McKay. Sklenar will appear in Amir Naderi's upcoming film Magic Lantern, in addition to films The Last Room and Glass Jaw. In June 2018, Sklenar was also cast in the independent drama film Indigo Valley, which is based on director Jaclyn's Bethany's short film of the same name. That same year, Sklenar was cast in a lead role in London Calling, a noir crime thriller that weaves the British gangster genre with the American western, opposite Ron Perlman, Malcolm McDowell, Nicholas Braun and Leven Rambin.
