Most sharks have a torpedo-like streamlined body, whereas skates and rays are defined by their flattened bodies.
In European waters, the name skate typically refers to the long-nosed larger species such as the White skate (Rostroraja alba) and the term ray refers to smaller species such as the Thornback ray (Raja clavata).
In fact these species are all skates because they lay eggs (oviparous), and the true rays are actually the species which give birth to live young (viviparous).
As with shark species, the wide range of marine habitats around our coastline means that we are lucky to have a large number of highly diverse ray and skate species
An impressive 33 species of rays and skates have been recorded in the Irish territory to date (correct as of Feb 23). These range from the relatively common Thornback ray (Raja clavata) to the Critically Endangered White skate (Rostroraja alba), which can grow to over two meters in diameter.
And our understanding is constantly evolving, and as such the previously known ‘Common Skate’ (Raja batis) is now considered to be a two distinct species – the Blue Skate (Dipturus batis) and the much larger Flapper Skate (Dipturus intermedius)
