How are rays and skates different from sharks
WebFor most shark species, females grow around 25% larger than males. The largest batoid is the manta ray (Manta birostris) which reaches widths more than 6.7 m (22 ft.). Body Shape. Sharks typically have a fusiform body (rounded and tapered at both ends). This shape reduces drag and requires a minimum amount of energy to swim. WebSkates and rays can be difficult to differentiate. Both are flat and (with a few notable exceptions, such as the eagle and manta rays) bottom-dwelling elasmobranchs sharing a similar diamond or rhomboid shape. Some of the most familiar forms occur together in coastal habitats.
