SWELL SHARK Cephaloscyllium ufer (Jordan and Gilbert) The swell shark produces the largest egg-case of the three Californian cat sharks. They range from about 90 to 125 mm long, and from 28 to 55 mm wide. The case is more rectangular and the tendrils are thicker than those of the two other cat sharks. At the anterior end, the short and thick horns taper to points that extend as coiled tendrils. Bending acutely toward each other, the anterior horns form an abrupt rounded end to the capsule; the area between the horns is deeply concave, almost circular. The horns at the blunt, posterior end are short, extending into relatively thick, coiled filaments (usually broken off in older specimens). The margin between the posterior horns is deeply crescentic. A constricted neck gives the case the characteristic vase-shape of cat sharks. The capsule tapers gradually toward the posterior end after flaring out from the neck, and constricts slightly just before the an- terior end, giving the lateral edges a gently undulating appearance. Freshly laid cases are light, transparent tan; the singh^ egg: or embrj'o can be seen inside. On exposure to sea water the case darkens but re- mains translucent. Length of time for hatching is not known, but Edwards (1920) found tluit a 48 mm embryo took 5 months to complete development and Avas 155 mm long Avhen Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
