When it's summer, get ready for chondrichthyes! CREATURE FEATURE: shovelnose guitarfish

During the spring and summer seasons, we see an increase of cartilaginous fish populations in the SF Bay. This week's creature is the shovelnose guitarfish The shovelnose guitarfish (Rhinobatos productus) is a medium-sized guitarfish (a group of skates) that inhabits shallow coastal waters from San Francisco Bay, CA to the southern Gulf of California, Mexico. With a compressed body shape, this species inhabits sandy or muddy waters typically shallower than 39 feet, but has also been recorded at depths of up to 300 feet! Their ability to pump water over their gills allows them to hover above the seafloor to feed on a variety of prey that also dwells at the bottom. Guitarfish exhibit an annual

When it's summer, get ready for chondrichthyes! CREATURE FEATURE: Pacific electric ray

During the spring and summer seasons, we see an increase of cartilaginous fish populations in the SF Bay. This week, MSI is featuring the Pacific electric ray The Pacific electric ray (Torpedo californica) is found only along the west coast of the United States. Typically found in sandy bottoms, rocky reefs, and kelp beds, we will occasionally catch them aboard the R/V Robert G. Brownlee in the San Francisco Bay estuary. Essential characteristics of this species are their round mobile body that has a very large first dorsal (top) fin and kidney shape electric organs on the side of its head. If provoked these species can control a charge causing numbness in humans and stun prey. This charge
